"For I am a chosen super-elite member of those who protect the peace of the galaxy!! A Galactic Patrolman!!"
Jaco is an alien with a mainly light blue head, save for his purple scalp. He has yellow eyes, and his nose and mouth are very human. His entire body is purple as well. According to Jaco, he is the third shortest out of the 38 Galactic Patrolmen, at 148 cm (4' 10¼").
Jaco is an alien who has a large amount of pride in his duties. He is also somewhat blank, as he was willing to use an Extinction Bomb to wipe out humanity just because Omori criticized them. He also views anyone who cannot live up to his expectations as inferior. However, this idea may be due to his extreme loyalty to his planet, so he will agree with their views on humanity. He also tends to get panicked quite easily. He also hates to be called short, as he nearly killed a civilian for it.
Not much is known about Jaco's past, except that it is mentioned that he once used the Extinction Bomb and destroyed some people, though he got harsh scolding from his seniors.
Jaco the Galactic Patrolman
Jaco is first seen in his spaceship flying to Earth, when he crashes on the Moon and is hurled towards Earth. He is later seen propelling his boat and carrying him on the dock. He asks Omori who he is, just what he wanted to ask. Omori notes how lucky the former is for having escaped the Monster Shark. Then he asks who Jaco is, and Jaco responds that he is an alien. At first, Omori expresses doubt, and Jaco calls himself a "Galactic Patrolman". Omori offers to fix his damaged spaceship, and when he can't figure out the mechanics of the spaceship, he squeezes Jaco's cheeks to confirm that he is an alien. Jaco reveals that he was on patrol when he got distracted by a video and smashed onto the Moon, and hit Earth. Omori says he would work on the spaceship in the morning, and invites Jaco to his house.
At the house, Jaco calls it "primitive lodging", presumably because at his planet, things are much more advanced. When Omori offers him food, Jaco says that he can only have milk and cheese, as it is the closest to what he eats at his planets. He reveals that the planet has sent probes to Earth, such as robotic flies. He also reveals that he had all the languages of the galaxy inputted in his brain, except he skipped the lesson about fixing the spaceship. Omori inquires whether Jaco's planet has a time machine, and Jaco replies no, saying that it's forbidden by the Galactic laws. Omori and Jaco both go to sleep, except Jaco only needed 30 minutes of it. He then goes for a swim, and then Jaco kills Monster Shark when it attacks Jaco. When Omori wakes up, he's impressed by how Jaco killed the shark, and Jaco reveals that Omori is now in his debt. They begin talking about a popular idol was going to go into space without any training to earn money. Before Omori goes to fix the ship. Jaco asks what the collapsed building to the right was, and Omori reveals his tragic past - it was a research lab until an incident occurred killing many people. Jaco notes that he was lucky they never succeeded, and Omori notes that there are too many bad people on the Earth. When Omori expresses doubt about being able to fix the spaceship, Jaco expresses disappointment in humans. He reveals his true mission - to save humans from a fearsome alien on a projectile coming in three days at 10:00 AM. Omori expresses contempt about humans, Jaco offers to use an Extinction Bomb to wipe out humanity from Earth. Omori instructs Jaco to never use it, and Jaco says that he will observe humans longer, but he may if he's annoyed. Jaco reveals that he once pressed the button on the bomb and killed people, but he got harsh scolding from the seniors.
In order to get some supplies, Jaco and Omori decide to leave the island for East City, where they meet a girl named Tights. Tights is being attacked by four muggers when Jaco saves her. She figures out that Jaco is an alien when he talks about the "Earth Police" and Omori tries to pass him off as a "foreigner from another country", but she says there are not any foreigners like him. Omori notes that Tights sounds like a name from the western region; Tights is from West City. When they remark the police are after them, the trio takes refuge on top of a building. The police are searching for Jaco after he beat up two of them and are calling him the "Mask Man"; they say the location where Jaco saved Tights is "Capital Ward 32", and the event happened at 8pm. Tights forces her way back to Omori's island by telling them that she might rat them out if they make her stay behind, so the trio leave the city and return to Omori's island thanks to Jaco's ability to fly via his boots, which can only be used in case of emergencies. At Omori's island, Tights reveals she is the one who will be on the rocket instead of the idol Ann Azuki, as it would be bad publicity if they lost their "super idol" in a launch mishap after all. This way, they can perform a "miraculous rescue" if the people in the rocket are killed. The money she used to buy the Sky Gold was her compensation for taking on the job. Meanwhile, Katayude is shown at home. As he is watching TV, Katayude sees Jaco on the news, remembering he saw him on Omori's island.
Tights leaves the island to be on the rocket and, a short time later, Katayude arrives with four soldiers to get Jaco. Jaco defeats the soldiers, and he and Omori use his spaceship to rescue Tights and the pilot from the crashing rocket. After kicking the rocket away from the city it was about to crash on, Jaco destroys the rocket with his Ray Gun. As they witnessed the whole scene, Katayude and the soldiers decide to let Jaco and Omori live in peace and leave the island. In the last chapter it is later revealed that the alien invader Jaco has come to defeat is a Saiyan. It is later revealed that the Saiyan that Jaco was looking for is Goku and he ended up at Grandpa Gohan's house, eating up a ton of food. Jaco was distracted and did not notice Goku's pod landing on Earth, so he thought Goku just did not show up.
While still on Omori's island, Tights is soon visited by her family on Omori's island, as her father Dr. Brief knew Omori by reputation for his work in space-time research. While meeting the Briefs, Jaco encounters Bulma who tests a powerful laser beam she planned to use on Jaco after hearing that there was an alien the island. While playing around, the five-year-old Bulma repairs Jaco's ship; As thanks for fixing his ship he offers them use of his gravity stabilizer which allows his ship to fly.
Ten years after parting ways, Omori, Jaco, Tights and Katayude reunite on the former's island for a temporary reunion. Omori is given plastic model of Z'Gok as a gift, which can be seen on top of his tractor at one point. During the reunion, it is revealed that in the intervening years, Tights forced Jaco to take her to visit a few planets before their ten-year reunion. Since then, Jaco got a girlfriend and Tights has become a talented Science Fiction writer, though her first novel Space Police Chako, based on Jaco the Galactic Patrolman, was a dud. Omori has just finished narrating how Tights' sister Bulma visited his island with her parents and met Jaco ten years ago and now, ten years after their first meeting, Bulma visits Omori again. Being a super-genius, Bulma has already graduated from university and has set out on a trip. She says something about looking for mysterious orbs that grant any wish when brought together. She shows off two, which are made of a substance that does not exist on Earth, so she reasoned they came from outer space. It all sounds quite suspicious, but space is vast, so perhaps this sort of mysterious orb exists out there somewhere. Omori notes that he will ask Jaco about it next time he stops by. While Jaco returns home after the meeting, Bulma is shown using her Dragon Radar and Goku is shown dragging his catch back to the house as in the first Dragon Ball chapter.

Resurrection ‘F’ Saga
Main article: Resurrection ‘F’ Saga Four months after Frieza decides to train to exact his revenge on Goku, Jaco heads to Earth to warn Bulma about the upcoming threat when he comes into contact with Goten and Trunks. He becomes surprised when he realizes Bulma has become a mother and becomes frustrated when the boys tease him for his appearance before introducing himself to them. The boys eventually bring Bulma to him so he can warn her about Frieza's comeback. He was shocked when she told him about Trunks defeating Frieza, that he came from the future and that the boys are half-Saiyan and that her husband is a Saiyan, and that he and Goku are training on Beerus' planet. Jaco eventually tells Bulma why he's here and plans to evacuate immediately.
Jaco escorts Bulma to North City where the Z-Fighters and Frieza. He plans to leave but stays because Bulma made him, saying he's an elite galactic patrolman. Jaco helps Gohan, Piccolo, Master Roshi, Krillin, and Tien Shinhan to a minimum while still combating some of Frieza's soldiers. Jaco says that Tagoma is beatable due to it being 5-on-one, excluding himself. When Goten and Trunks arrive and wonders what the Ginyu Force is, Jaco explains to them that the Ginyu Force is a group of elite soldiers under Frieza.
Universe 6 Saga
Main article: Universe 6 Saga Jaco is on a planet building rocks when he gets a call from Tights and is told to go to Earth to see Bulma. When reaching Earth, Jaco is mad that Bulma is calling him for the smallest things. When Bulma asks him to take her to the center of the universe to find the last Super Dragon Ball, Jaco reveals that the universe has many galaxies, instead of four. He suggests that she goes a see a mysterious one named Zuno who knows everything. Bulma insists that he took her to see him. Jaco agrees to take her to see him.
On the way to Zuno's planet, Jaco is informed of the existence of more universes and the Super Dragon Balls, which he had no knowledge of, even as an elite soldier of the Galactic Patrol. Jaco is interested in spectating the universe tournament and it was a suggestion by Bulma to bring his girlfriend. She however dumped him, using an old-fashion line.
When they arrive, they are stopped by one of Zuno's attendants. One of his attendants tells them that Zuno isn't taking non-appointed guests and would have to wait seven years for an appointment. they visit Zuno in his room. Jaco has to present a gift for Zuno to ask him questions. Jaco wants to give him a kiss but Zuno obliges and only give him one question for being a male. Jaco uses the question to ask Zuno about Bulma's bust size, which is 83.4 centimeters after breast feeding. Bulma is given three questions because she is a woman but middle-aged. She uses two of her questions by mistake but manages to get one question about the origin of the Super Dragon Balls. Jaco gets mad at Bulma for wasting two questions and they are both forced to leave but can come back a year later for more questions.
Five days later, Jaco attends the Universe 6 and 7 Gods of Destruction Selection Martial Arts Competition with the Galactic King. On the way to the Nameless Planet, when the Galactic King is upset that no one is giving him attention, Jaco explains to the Galactic King that they have met beings over the King like the Kais and the Gods of Destruction. The eventually arrive on the star, after playing a game of Shiritori. Jaco is a bystander for this tournament so he sits with Universe 7's guests. After the referee introduces the singer and he sings the universe anthem, the first match is between Goku and Botamo. Goku beats Botamo by pushing his down and throwing him out of the ring because he couldn't do any damage to him, resulting in a ring-out. Goku immediately is next challenged by Frost. While Goku and Frost are fighting, Jaco notices something happen when Frost connects a punch to Goku, resulting in Goku getting drowsy and losing his match against Frost. As Frost was about to be announced to be the winner against his match with Piccolo, Jaco noticed something was wrong and suggested to the referee that Frost was using poison to win his matches. Following Jaco's advice the referee checked Frost's body and discovered the needle concealed in his right arm much to everyone's surprise including Champa and Cabba.
Later on, when Vegeta was defeated by Hit, Goku approaches Jaco and asks him if he can see his movements, and Jaco replies that he cannot. The Galactic King realizes that Hit is using the Time-Skip technique, which Jaco recognizes. Goku asks Jaco if he is going to arrest Hit for manipulating time, as that is a Galactic violation, but Jaco, concerned for his own safety, says he will overlook it. He then spectates Goku and Hit's match, and the arrival of Zeno.
Jaco attends the Universe 7 victory party thrown by Bulma on Earth. Jaco has ordered some special snacks that Monaka has delivered, leading Bulma to realize that Beerus and Whis did not invite Monaka to the party despite her telling them to. Jaco then finds out Monaka's secret and is tasked to assist protecting it from Goku. Jaco then witnesses Goku's battle with "Monaka" (Beerus in a Monaka costume), and then the party commences.
When Goten and Trunks stowed away on Monaka's delivery truck and end up on Planet Potaufeu, Jaco is asked by Bulma to go retrieve them. Jaco refuses, stating he has other matters to attend to, such as capturing the intergalactic criminal Gryll (not aware that he is currently on Potaufeu). Bulma then blackmails Jaco, using the picture of the Galactic King with a drawn-on mustache that Bulma saw in Jaco's spaceship. Jaco then finally agrees to retrieving the two boys, and Bulma makes Vegeta accompany Jaco on the trip. On the way to Potaufeu, Jaco is listening to a universal radio station, intimidated by Vegeta.
Having arrived on Planet Potaufeu, Jaco is surprised to see that Gryll, his target, is there. He witnesses Vegeta being absorbed by Commeson and his copy emerging. As Copy-Vegeta tries to absorb Trunks, Jaco saves him by shooting at Copy-Vegeta's tentacles with his Galactic Patrol gun, striking a pose. As he is posing, he realizes that the others have escaped, and narrowly escapes on his own after Copy-Vegeta and Copy-Gryll try to absorb him.
Later, as he explains that the "Superhuman Water" can increase the drinker's strength a thousand-fold, Potage, Potaufeu's only inhabitant, announces that Commeson is actually a weapon, and the whole "Superhuman Water" idea were false rumors created by non-inhabitants, much to Jaco's surprise. Jaco later witnesses Copy-Vegeta's fight with Gotenks, being the first to point out that Vegeta's body was growing transparent due to Commeson's effects.
Future Trunks Saga
Jaco was at space ramen stand where he waiting to eat ramen, however while he was distracted a dangerous parasitic criminal named Watagash that he had captured earlier had escaped his spaceship. Jaco manages to follow him to earth however when he comes across Gohan dressed as the Great Saiyaman flying with a pop idol named Cocoa. He mistakenly believes that Great Saiyaman was infected by Watagash and threatens to use his spaceship's energy canon.
Main article: Dragon Ball Z: Resurrection ‘F’
"How can one Earthling have that much strength?!"
Four months after Frieza's revival, Jaco headed toward Capsule Corporation, where he was able to reunite with his old friends Dr. Brief and Bulma. Jaco says he's heard that Bulma was friends with the one who defeated Frieza from Tights, causing Bulma to explain that Frieza was actually defeated by two people, the first being Goku while on Namek, and the second being her teenage son, Future Trunks. Jaco was stunned by Bulma's nonchalant attitude towards Time Travel reminding her it is a serious violation of Galactic law. When Bulma explains that Goku is training with her husband at Lord Beerus' planet, Jaco is skeptical of her claims about Beerus' existence as he considers Beerus the Destroyer to be a myth. Jaco then warns her that Frieza is on his way to Earth with a thousand soldiers. Bulma attempts to summon Whis through a strawberry sundae offering, but when nothing happens, she decides to let everyone know about the situation herself.
Jaco gave Bulma a ride on his spaceship, but was not interested fighting until Bulma reminds him that protecting the Earth is his job. Jaco took on some of Frieza's soldiers when he was helping the Z-Fighters. He is impressed by their strength and is surprised that Earthlings like Krillin are so powerful. He later watches the battle between Goku and Frieza and later Vegeta. He is surprised by Goku's strength believing it to be impossible for an Earthling to have such power, causing Bulma to reveal that Goku and her husband Vegeta are actually Saiyans, causing Jaco to pretend he didn't hear anything about Saiyans on Earth when he was to report to his boss about it, as it was originally his job to keep Earth Saiyan-free. When Frieza noticed Beerus, Jaco asked Bulma if he could get a picture with Beerus the Destroyer but, she said that he was taking his chances.
After a while, Goku is being beaten by Frieza with the help of his henchman, Sorbet. Vegeta steps in so he could kill Frieza. However, Frieza destroys the Earth before Vegeta could kill him. Jaco is saved by Whis along with the others there except Vegeta. Whis has the ability to turn back time three minutes prior and he lets Goku kill Frieza. After Goku kills Frieza, Bulma asked Jaco if it's really alright for him to not arrest Whis, since control over time was a serious offense, so he pretended he didn't see a thing when he reported to his boss about Earth.
As Omori noted, Jaco possesses a large amount of strength, as he was able to push a broken spaceship quickly enough to out swim an enormous shark. He was also able to kill the shark with one club to the head. It was further proved when he was able to destroy a boat by throwing a small rock at it. He also sent flying a detached rocket out of bounds of the city and into the ocean with a single kick. Jaco claimed that all members of Galactic Patrolman are "super elites," although later he has mentioned that he would be easily defeated by an adult Saiyan warrior. When Jaco met with Bulma (at the age of five), he was stunned by the destructive power of the laser gun that Bulma created. He asked if Bulma would like to join Galactic Patrol.
By the time of Frieza's arrival on Earth, he was capable of holding his own against a group of Frieza's soldiers in combat. His Galactic Patrol Gun also proved capable of easily knocking down Frieza's soldiers with carefully aimed shots to their legs. Jaco is shown to be a more strategic fighter, at one point leading a large group Frieza's soldiers to fire Ki Blasts at him while he was underwater causing them to disturb a giant sea creature which ended up eating the soldiers in retaliation, demonstrating strategic cleverness on his part as it allowed him to eliminate a large group of enemies easily and allowed him to conserve some of his stamina enabling him to stay in the fight longer. However, Jaco was still far too weak to take on Shisami, let alone Tagoma, Ginyu, or Frieza.
