"With my omniscient vision, I can see girls playing volleyball on the beach!"
Old Kai is average height, purple skinned, with a small tuft of white hair on his head and a small mustache on his face. His face is very wrinkled, showing his age. He wears a typical Kai outfit with teal underclothes. Prior to his Fusion with Old Witch, he had a purple mohawk and a much younger face, giving him an appearance similiar to Shin.
Old Kai's personality and demeanor are very lecherous and self-centered, but with the capability to make a sacrifice at the right time if the need arises, very similar to Master Roshi. He has a very perverted mind and loves Dirty Magazines; as a matter of fact, one of Goku's first bribes to him was loaning him some of Master Roshi's "Girlie Magazines", much to Gohan and Shin's chagrin. It is shown during the Majin Buu Saga when Goku bribes him to find out a power that he is boasting about, but Old Kai says he can use his vision to see girls play beach volleyball (in the original manga, he simply states he can watch them strip if he needs to). He eventually accepts the offer to be able to kiss an Earth woman; in the original manga, it is pornography of one, and in the Japanese dub of the anime, it is to grope Bulma's breasts, much like Master Roshi wanted to multiple times throughout Dragon Ball and DBZ. He is also somewhat childish at times, as he throws a tantrum because he "can't see all the action" inside Buu, and also throwing a tantrum when he learned that the Namekian Dragon Balls had been altered, while also reading comedy comics while powering up Gohan and stating that he can not think on an empty stomach. He also falls asleep at inappropriate times, once during Gohan's power up. Despite these tendencies, he can be considered to be one of the wisest characters in the series as he has frequently displays knowledge that no other Kai has shown, including the Potara Fusion, the fact that Super Buu follows Goten and Trunks into the Hyperbolic Time Chamber, and the knowledge of Super Saiyan 4 in Dragon Ball GT.
Old Kai has the power to raise a being's ability to more than their normal limits and beyond what anybody else can unlock, including Grand Elder Guru. This was gained from fusing with the Old Witch. He often boasts and calls it his "menacing capacities". The ritual begins with him slowly pacing around the participant for five hours making brief shouts. During that time the participant has to stand patiently. Afterwards, they both sit facing each other for twenty hours, a process that may take longer should the participant's potential be that much higher. During this time the participant must be still, but Old Kai is able to do things such as read, which further frustrates Gohan. He also has other powers like the ability to create objects out of nothing, a power common in the series, and the ability to view things in any world at any time (although for some reason, he is entirely unaware of the Dragon Balls' existence on Earth though he knows all about Majin Buu's reign of terror on the planet).
In Dragon Ball Xenoverse 2, it is shown that he retains a grudge against Beerus for sealing him within the Z Sword and he has a bad habit of speaking to himself though loudly enough for other people to hear, which one Time Patrol attributes to his age. Despite his grudge he puts on a friendly act around Beerus when he accidentally bumps into the god when he appears in Conton City after Mira's defeat, though it is spoiled when he complains to himself loudly enough for Beerus to hear him and is almost destroyed by the deity, though is saved by the intervention of Whis. Additionally, his lecherous habits have not changed and several female Time Patrollers mention him peeking up their skirts or groping them. He even causes a female Majin to become worried about her body image for most of the game, after she overhears an him commenting to himself about her appearance. Though he usually manages to get away with it, one of the female Time Patrollers reveals she attacked him when he attempted to grope her while she was having tea with Chronoa, causing the Supreme Kai of Time to praise her for defending herself from Elder Kai's lecherousness. Despite these negative qualities, Elder Kai is shown to think highly of his student, the Future Warrior as he suggested them to Chronoa for the critical mission. However he tries to keep his true feelings from the Warrior in order to keep them from getting a big head and maintains a stern attitude around them, even denying his true opinion when Chronoa reveals how highly he thinks of the Warrior's abilities. He is shows concern for his student's well-being when they confront Mira in his final form, telling them to flee as Mira had become to powerful. He also admits he doesn't agree with the development of Future Bulma's time machine, but does not dwell on it as it is already a part of established history. He dislikes being call old by Chronoa who is only a millennium younger than him (as Shinjin have long life spans) and is disappointed that Chronoa's appearance has not changed in 75 million years since he last saw her. Though he and Chronoa are shown to be able to work together, Elder and Chronoa are prone to arguing at times. He also retains his negative opinion about the usage of the Dragon Balls as he complains when Chronoa summons Shenron to wish up a feast to celebrate the defeat of Mira and the return of Tokitoki's Egg and only backs down when Beerus reminds him that it is a festive occasion (presumably not wanting to upset the God of Destruction by complaining further). He also states his disapproval of the use of the Namekian Dragon Balls during the Battle on Planet Namek despite knowing full well is an established part of history. Though he works as the administrator of the Time Patroller Academy and oversees the training off new recruits at Chronoa's request, he is shown to lack knowledge or only knows certain portions of historical events he was not present for such as the Battle on Planet Namek and Androids conflict, as he is more familiar with the Majin Buu conflict and Frieza's revenge. For example, he was unaware of Ginyu's Body Change technique and assumed that the Large Spirit Bomb would defeat Frieza on Namek though this may be due to him being more familiar with the stronger Super Spirit Bomb which destroyed Kid Buu. He also showed confusion about why it was bad that Imperfect Cell had absorbed by Androids together forcing Xeno Trunks to explain that it was Cell's fights with Vegeta and Future Trunks that lead him to come up with the Cell Games, which may not occur due to him obtaining his Perfect form much earlier. However he is quick to point out his own role in unlocking Gohan's potential during the battle with Super Buu and warns Xeno Trunks he shouldn't not to underestimate the revived Frieza and explains that Frieza is a prodigy who never trained a day in his life until this point and that it will take more than a swing of a sword to defeat him this time. Elder Kai is also shown to forget details of events where he was present such forgetting the written test from the Universe 6 and 7 Gods of Destruction Selection Martial Arts Competition, which Chronoa admonishes him for and attributes to his old age.
BackgroundIn the past, Old Kai visited Zen-Oh three times. One day, an Old Witch snuck up on the Former Supreme Kai while he was reading a comic book and took one of the Potara Earrings that he was wearing, leaving the Supreme Kai with a horrified expression as he knows about the abilities of the Potara Earrings. She put the earring on her ear which caused the two to fuse. This caused him to become an old wrinkly being with a personality befitting of the new form, as well as new magical powers. Once every 1,000 years, the Supreme Kais and the Gods of Destruction go to each other's realms and hold a coordination meeting. During one of these meetings, held roughly 75 Million Before Age, they got into an argument over some trifling thing and a certain short-tempered, Beerus, sealed Old Kai away inside the Z Sword as it would not have been proper for him to destroy the Sacred World of the Kais itself. According to Old Kai, the person who sealed him inside the sword was very powerful but not as powerful and bad as Majin Buu.
Dragon Ball Z
Majin Buu Saga
Main articles: Majin Buu Saga, Fusion Saga, and Kid Buu Saga Shin and Kibito were looking for warriors they believed would be strong enough to defeat Majin Buu. They eventually ended up with Gohan and had him remove the Z-Sword from its stone encasement. Goku eventually showed up, and started to help Gohan train. To test the blade, Shin generated a cube of the strongest metal in the universe, Katchin, and gave it to Goku to throw. When Gohan hit the metal, the Z Sword broke in half, releasing Old Kai. After Old Kai expressed disappointment in Shin and Kibito for not breaking the sword's seal yet Gohan, a mortal, was able to break it, Goku tried to test Old Kai's power level by throwing a basic Ki Blast at him, with little enough power to deflect, and it instead knocked Old Kai down, resulting in Old Kai scolding Goku.
Old Kai told them that he could bring out Gohan's latent abilities by doing an "essential ritual". After waiting for well over an entire day, Old Kai had finally unleashed Gohan's hidden potential. After Gohan lost to Super Buu, Old Kai revealed the method of Potara Fusion to Goku and gave him the Potara Earrings to fuse with Gohan, (though Goku would end up fusing with Vegeta, creating Vegito).
He then gives up his life to Goku so he can return to Earth to fuse with Gohan and defeat Buu. When they decided to use the Namekian Dragon Balls to restore Earth and revive everyone, Old Kai refused to use them, as he claims that they would disrupt the balance of nature. However, he went along with it when Goku reminded him of his deal regarding his groping/gaining nude pictures of/going on a date with a human woman, with Goku inadvertently admitting in front of Vegeta that the woman in question was Bulma. When Super Buu reverted to Kid Buu, Old Kai went to Namek with Dende and Kibito Kai, where he and the others used the Namekian Dragon Balls to help Goku and Vegeta defeat Kid Buu. Old Kai was brought back to life by the wish made to Porunga to revive everyone who died after the 25th World Martial Arts Tournament, and so his halo disappeared after the wish was made.

The celebration is interrupted by a brother duo, Abo and Cado, whom are after Vegeta's brother Tarble. The brothers are challenged by Goten and Trunks but they fail in defeating them. The brothers, merged as Aka, unleash a technique that destroyed the hotel. Aka is then defeated by Goku with a Kamehameha. After this encounter, they continue their feast.

God of Destruction Beerus Saga
Main article: God of Destruction Beerus Saga Sometime after Kid Buu's death, Old Kai and Kibito Kai notice a planet's disappeared and wonder what's to come of the universe. While the two were having tea, Old Kai senses that another planet has disappeared and tells Kibito Kai that the God of Destruction Beerus has been awoken and that the universe is in serious trouble.
Golden Frieza Saga
Main article: Golden Frieza Saga After the fight with Goku and Beerus, Old Kai and Kibito Kai are wondering about the recent mysterious disappearance of some planets, as if they disappeared by magic. When Old Kai suddenly gets distracted, Kibito Kai assumes he is using his divine sight to peep on women or something equally perverted, but he turns out to instead be watching two horned beetles wrestle.
Universe 6 Saga
Main article: Universe 6 Saga
Old Kai attends the tournament on the Nameless Planet with Shin and Kibito to spectate the battles between the members of Beerus' and Champa's teams. When Fuwa wonders if Old Kai knows Goku, Old Kai says it's a long story. Old Kai is a bystander and so he sits with the other gods. The first match is between Goku and Universe 6's fighter Botamo. While Goku is fighting Botamo, the Universe 6 Supreme Kai thinks that Botamo has the advantage over Goku but Old Kai doesn't think so.

Dragon Ball GT
Main article: Baby Saga
Old Kai plays a prominent part towards the middle of the Baby Saga: he helps Goku's tail grow back to help him fight Baby, which later allows Goku to ascend and transform into Super Saiyan 4. For some reason, he knew about the Super Saiyan 4 form, indicating that there were Super Saiyan 4s before Goku's time. In the Shadow Dragon Saga, he and Kibito Kai explain to the Z Fighters how the Shadow Dragons were born from the negative energy that was stored in the Dragon Balls, after years of overusing the balls to grant wishes thus proving Old Kai's previous warnings about using the Dragon Balls upsetting the nature order correct. As the GT series comes to a close, both he and Kibito Kai watch Goku defeat all of the Shadow Dragons and restore the natural order of the universe.
Shadow Dragon Saga
Main article: Shadow Dragon Saga
Before the Shadow Dragons are born, Old Kai gives an ultimatum to Goku that the Dragon Balls they are using are very dangerous and have the potential to destroy the whole universe. Since he does not provide an explanation, Goku and others assume that he is simply being prudish, and proceed to use the balls without heeding his warning. Later, with the birth of the Shadow Dragons, especially Syn Shenron, the Z warriors are able to understand what Old Kai had feared. Additionally, when he reminded Bulma that she was equally responsible for the crisis by having invented the dragon radar as a means of locating the dragon balls for her own selfish interests, Old Kai admitted disgust at how he had allowed the fate of the universe to rest on a kiss from her.
Battle of Gods
Main article: Dragon Ball Z: Battle of Gods Four years after the battle with Majin Buu, Old Kai is with Kibito Kai when they and King Kai are telepathically discussing the awakening of the God of Destruction Beerus. They appear again after Goku's battle against Beerus and comment on Goku befriending the God of Destruction.
Other Dragon Ball stories
Main article: Dragon Ball Xenoverse In Dragon Ball Xenoverse as part of the Resurrection ‘F’ Pack DLC, Elder Kai decides to visit the Time Nest in Age 850 and is surprised to find the thriving metropolis of Toki Toki City near by as it did not exist during his previous visits to the Time Nest. He offers to take the Future Warrior as a student allowing the Warrior to take on Elder Kai as a Master. Unlike other Master's Elder Kai will not train the Warrior directly (due to Elder Kai not being a fighter).
During the Warrior's second training mission "Defeat Yourself!", Elder Kai will create a doppelganger of the Future Warrior's Ego which the Warrior will face in battle. After defeating their Ego once, it will revive in Villainous Mode, forcing the Warrior to defeat it once again. After their Ego is defeated, Elder Kai will reveal that the Warrior had just defeated their own dark ambitious ego that was hidden deep within themself, thus helps the Warrior cleanse themself of their growing dark inner ambitions.
At one point he will recall the many random and strange events that have occurred on Earth (the Saiyan baby Kakarrot landing on Earth, Kami's creation of the Dragon Balls, Future Bulma's Time Machine changing history, and Majin Buu being sealed away in the Sealed Ball) and muses how those events have made Earth a key planet in determining the fate of the universe, and how fate can be both interesting and cruel. He will also lecherously ask the Future Warrior the number of female Time Patrollers, while insisting he asked only out of curiosity and in the name of research. If a Female Future Warrior talks to him while wearing Kid Chi-Chi's Clothes (the Bikini Armor Chi-Chi wore as a young girl), he will be very pleased to see the Warrior wearing it (due to his lechery) and call them a master pleaser. If the Warrior talks to them wearing Supreme Kai Clothes, he will ask if they want to become a Supreme Kai too, only to inform the Warrior that only a select few are able to become Supreme Kai and says that being strong isn't enough to become one, before telling the Warrior to focus on what they do best. If the Warrior talks to him wearing Gogeta's Clothes, he will recognize them as being Metamoran garb produced by Fusion. He wonder why the Metamoran's pose in such a silly way to fuse themselves and says if one is going to pose to fuse then it should be done in style.
He will also use his Old Kai's Unlock Ability ritual to unlock the Warrior's potential allow the Warrior to use the Unlock Potential transformation Ultimate Skill which is accessible to all races. In addition to the Unlock Potential skill, completing Elder Kai's training will unlock the Emote Elder Kai's dance, based upon the dance he used at the beginning of the ritual. In the game, he is referred to as Elder Kai.
Main article: Dragon Ball Xenoverse 2 In Dragon Ball Xenoverse 2, Elder Kai runs the Patroller Academy at Orange Star High School in Conton City. Some point in between Age 850 and Age 852, Chronoa asked for Elder Kai's assistance in handling some of the Time Patrol's administrative duties such as training new Time Patrollers. During his time at the Academy, Elder Kai sees promise in one of the new Time Patrol recruits, to the point he suggests that Chronoa assign them for a critical mission. This recruit is the game's main protagonist, the Future Warrior (Xenoverse 2). After Chronoa selects them, Elder Kai contacts them via the Time Patrol's Scouter communications, just as they are about to receive an assessment of the situation in a time rift (which changes depending on the Warrior's selected race) they are currently investigating. After arriving in Conton City and being greeted by Chronoa, the Future Warrior is forced to search for Elder Kai. While on his way to the entrance to the Time Nest, Elder Kai ogles some of the female Time Patrols, even pretending to fall down to peek up a girl's skirt, which the Future Warrior will point out to the girl when they talk to her (as they are apparently fully aware of Elder Kai lecherous personality). Eventually the Warrior meets Elder Kai in front of the entrance to the Time Nest, who admonishes them for being late, despite it being his fault. Before they can talk further, Chronoa appears and offers to instruct the Future Warrior in the basics of battle before they start their mission. Afterwards Elder Kai has the Warrior travel to Age 761 to assist Goku and Piccolo against Dark Raditz. Elder Kai criticizes the Warrior's poor entrance after when the forget to use flight after being transported into the air, causing them to fall to the ground. Despite this setback, the Warrior manages to weaken Raditz, allowing Piccolo and Goku to defeat Raditz with the Full-Nelson Special Beam Cannon. Back at the Time Nest, Elder Kai congratulates them on their success and says they did well, except for their entrance. Chronoa appears and tells Elder Kai to stop rambling on. Elder Kai takes offense to Chronoa calling him Old Man and states he is only about a millennium older than her, which hardly makes him an old man (as Supreme Kais have longer life spans compared to mortals) which leads to a brief argument between the two Supreme Kais. As Future Trunks and his partner Ace (the Future Warrior from Xenoverse) are busy with tracking down the Time Breakers, Elder Kai acts as the Warrior's mission controller, providing them with information and advice alongside Chronoa.
In terms of power, the Old Kai is much weaker than the other Supreme Kais, as when Goku wanted to test the Old Kai to see if he was powerful, he fired an uncharged ki blast at him while only in his base form, with even this weak attack managing to injure the merged Shinjin and knock him down. However it should be noted that Old Kai's weakness may be due to a combination of his age and the fact that he had been sealed within the Z Sword for 75 Million years.
While Old Kai may lacks physical power, he possesses vast wisdom and powerful magical abilities thanks to his fusion with the Old Witch which allow him to unlock the potential of others, both of which proved invaluable during the Majin Buu conflict and Dragon Ball GT.
- Video Games
In Xenoverse 2, by working in conjunction with a fellow Supreme Kai like Chronoa, Elder Kai can erect an self-sustaining invisible barrier large and powerful enough to protect both Conton City and the Time Nest from direct attack by even beings as powerful as Towa and Mira (as the Time Breakers never tried to attack the city or Time Nest directly), forcing Towa to find a more subtle way to bypass it. However it required both Elder Kai and Chronoa combined to create it and is the result of their divine powers combined.
Additionally Elder Kai uses his wisdom and experience to train new Time Patrollers at the Time Patroller Academy. One of these students would go on to become the 2nd Future Warrior who saved the Universe by killing Final Form Mira after he had absorbed Towa in Age ???.
- Ki Sense - The ability to sense ki. As he is a Supreme Kai he can sense both normal ki and godly ki.
- Unlock Ability – Old Kai's most powerful technique. After a long and even bizarre ritual (whose length depend of how much power the person in question has to be unlocked), Old Kai is capable of bringing out the full potential of any person that he wants.
- Life Transfusion – Old Kai can exchange his life for the life of a dead person, bringing them back to life and killing Old Kai. Since he was already quite old (having just one last millennium of life, which is an extreme sign of aging considering that his kind can live well over 75 million years), Old Kai decided to sacrifice his life to revive Goku so that he could fuse with Gohan after Super Buu absorbed Gotenks and Piccolo. Old Kai collapsed for a moment, but since he was already in the Other World, he woke up again in a comical fashion and merely gained a halo.
- Magic Materialization – Old Kai conjured a Crystal Ball to see what was happening on Earth.
- Divination – Through his Crystal Ball, Old Kai is able to see whatever he wants across space and time. He used this ability to voice his wisdom and concern over the Z Fighters' fight against Super Buu and Kid Buu, though this ability was temporarily blocked when Buu literally goes inside of his head, much to Old Kai's chagrin. In Dragon Ball Xenoverse, it is shown that like Fortuneteller Baba, he is also capable of telling a person's fortune via this technique as well, as he will use it to tell the Future Warrior's fortune.
- Far-Seeing Arts – Technique which allows those who live in the godly realms to see everything that happens in the lower realms. He also claimed that he can use this ability to observe Earthly women playing volleyball on the beach (watching Earthly women strip naked in the manga) when refusing Goku's bribe of some of Master Roshi's girlie magazines, to Shin's disgust.
- Fission - Old Kai can separate a person from their ego or their "bad vibes" and personify them, allowing them to literally defeat their bad natures. Old Kai uses this technique in Dragon Ball Xenoverse to give the Future Warrior more power for their unlock potential ritual and to help the Future Warrior defeat the growing darkness hidden deep within themselves.
- Healing - As a Kai, Old Kai possessed the ability to rejuvenate anyone and restore them to full health instantly, even if they are on the brink of death.
- Barrier - After joining the Time Patrol as an instructor, Elder Kai and Chronoa decided to use their divine powers to erect a barrier around both Conton City and the Time Nest to protect them and prevent further incursions like what occurred during the Demigra Incident. This invisible barrier once erected was large and self sustaining, allowing Chronoa and Elder Kai to focus on their duties, while the barrier protected both the city and Time Nest. However Towa figured out a method to bypass it by tricking Xeno Trunks and the 2nd Future Warrior to bring the Masked Future Warrior's mask back with them to the Time Nest, which eventually allowed Towa to infiltrate the Time Nest and steal Tokitoki's Egg. The barrier could also be bypassed by temporal anomalies like Wormholes which allowed Frieza's Spaceship to bypass the barrier during Frieza's Siege.

- Is implied that Old Kai is the eldest Supreme Kai still alive in all Dragon Ball franchise (as he claims to be 1000 years older than Chronoa) and one of the three Supreme Kais of Universe 7 known to have not been killed or absorbed by the original Majin Buu (due to it being sealed in Z Sword).
- Despite being dead, Old Kai was able to leave Other World and travel to the world of the living without the help of Fortuneteller Baba. It is possible that his prestigious position in the universe allowed certain privileges to make this possible, or it could be the witch he fused with having the same powers as Baba.
- There is a scene where the crystal ball malfunctions and Old Kai says "They don't make crystal balls like they used to." Kibito Kai says "But I made that one myself!" Old Kai was the one who made the crystal ball, not Kibito Kai/Shin.
- When powering up Gohan, Old Kai reads a comic book. At times he is shown flipping the pages from right to left, implying the book is written in Japanese order like manga. However, at other times he is shown flipping the pages left to right. This could be explained by the comic having panels which hold his attention, giving him the desire to turn back to them occasionally.
- Old Kai's wisdom has assisted in the creation of three of the series' most powerful transformations: Ultimate Gohan, Vegito and Super Saiyan 4 Goku.
- Despite continuing to work alongside Shin as a Supreme Kai for Universe 7, Elder Kai apparently does not have an official status of it anymore. This was seen from Beerus' concern only for Shin as a life-link to him. Even more, in Dragon Ball Xenoverse 2, Beerus was willing to kill Elder Kai, only stopped by Whis' timely distraction with food.
- However it should be noted that Xenoverse 2 takes place in Age 852, while Beerus comes from Age 779, so its possible that Beerus killing Elder Kai in Age 852 would not effect him (provided that the Elder Kai in Xenoverse 2 originates from Age 852) similar to how Zamasu's destruction in Dragon Ball Super did not effect his alternate counterpart Future Zamasu.
- Also considering Elder Kai's age and the history between them, Beerus may have elected to have his life linked to only Shin who is younger and would be easier for Beerus to get along with.
- Before he merged with the witch, Old Kai looked nearly identical to Shin, except his skin and hair were violet rather than purple.
- Old Kai knew of the Golden Great Ape and Super Saiyan 4 transformations, and even called the latter by name after Goku transformed, yet he did not seem to know why Goku's power level did not increase at all before transforming. Also, in the Kid Buu Saga, he did not suggest the transformation as a means to beat Buu.
- One possibility it was unmentioned during the Buu Saga is due to the dangers posed by Golden Great Ape transformation (as Elder Kai may not have been aware that Vegeta could control himself in the form and would able to access the form easily as long as he had his tail) and the tail pulling technique he used to restore Goku's Saiyan tail, may only have worked on Goku in GT due to being in the body of a child at the time (as Saiyans tend to regrow their tails most often during childhood), thus Elder Kai may not have suggested it as he knew it would not work on adult Saiyans (Elder Kai also would not have known that Golden Great Ape transformation could be induced artificially using a Blutz Wave Generator as that was only theorized and discovered by Bulma after Goku became a Super Saiyan 4).
- In Dragon Ball Z episode 273 "The Innards Of Buu", Old Kai says that he has trouble digesting Mexican foods, though like the countries mentioned in the movie Dragon Ball Z: Super Android 13!, Mexico does not exist in the Dragon World.
- He is the second Kai to experience death during the series, after King Kai (at least on-screen, because the other Supreme Kais were killed off by Buu long before).
- Old Kai and Master Roshi have very similar qualities; both are incredibly old (even for the Kaioshin's race), both are extremely perverted and both have great wisdom for their students. Goku even noted the similarity once when he made a deal with Old Kai to have him unlock his son's full potential.
- In Dragon Ball GT, during the Shadow Dragons Saga, in episode 61, Old Kai can be heard listening to the original FUNimation Dragon Ball GT opening theme song, and singing along. In other non-American versions, he listens to Dan Dan Kokoro Hikareteku.
- In Dragon Ball Xenoverse, Elder Kai is shown to really like Kid Chi-Chi's Clothes (due to its skimpy bikini style armor) if a Female Future Warrior (as it can only be worn by females) talks to him while wearing it. Additionally, he often gives the Future Warrior pieces of that outfit as random gifts.
- In Dragon Ball Xenoverse 2, Elder Kai does not uses his ritual to unlock the 2nd Future Warrior's potential. Instead they obtain the Potential Unleashed Awoken Skill by completing the final Advancement Test for Super Class at the Patroller Academy. However it should be noted that Elder Kai is in charge of the Academy and oversees the test itself, so it is possible that he developed the test as an alternate way to unlock the potential of his students at the Academy (as the ritual probably would take up too much of his and his students time making it unsuitable for both the Academy and the Time Patrol). However it is also possible that the ritual simply occurs off screen after the Warrior passes the test.
- Elder Kai and Gowasu have several things in common: both are elderly, both are Supreme Kais (though Elder Kai operates in a retired capacity) and both have died twice. More is explained below:
- Elder Kai's first death was in the main timeline. He gave his life to Goku so that the Saiyan could return to Earth to help his son Gohan in the battle against Majin Buu.
- Elder Kai's second death was in an alternate timeline. He was still trapped in the Z Sword when Future Dabura turned the weapon in Future Trunks' possession to stone. It then shattered.
- Gowasu's first death was in an alternate timeline. Zamasu killed him in order to assume the role of Supreme Kai and steal the Potara earrings and the Time Ring. However, this death was undone when Whis used his Temporal Do-Over to rewind time and thwarted Zamasu's attack.
- Gowasu's second death was in the main timeline. He and all of Universe 10 (with the exception of Cus) were erased from existence entirely by Zen-Oh and Future Zen-Oh after Team Universe 10 was eliminated from the Tournament of Power.
