Mimicry refers to the coveted ability to copy another fighter's technique after seeing it used only once.
It was first used by Goku when seeing Master Roshi doing a Kamehameha to extinguish Fire Mountain in Dragon Ball. Then, by Tien Shinhan during his quarter-final match with Yamcha during the 22nd World Martial Arts Tournament: Yamcha fires a powerful Kamehameha at Tien only to have it nullified and reflected by Tien's Kiai blast. Tien then later surprises everyone by firing his own Kamehameha at Jackie Chun during their semi-final match. During the final match, Goku develops King Chappa's Hasshu-ken technique in retaliation against Tien's Four Witches Technique.
In the Vegeta Saga, Chiaotzu is also shown to be able to use the Mimicry ability: after witnessing what the Saibaman's Self Destruction technique did to Yamcha earlier in the battle (Saibaman Bomb), Chiaotzu decides to copy it himself and later uses his version of the technique (named Farewell, Mr. Tien) against Nappa, to no avail however. Chiaotzu also uses a Masenko-like technique in the movie Dragon Ball Z: The Tree of Might. Vegeta copied Krillin's Destructo Disk, using it to cut off Gohan's tail when the latter was in Great Ape form. Vegeta also managed to learn Ki Sense after his fight against the Z Fighters.
In his 100% Power form, Frieza uses a variation of Krillin's Destructo Disk technique called the Homing Destructo Disk in an attempt to kill Goku. He witnessed the technique when Krillin cut off his tail while Frieza was in his second form. Frieza also uses it in Dragon Ball GT, which Goku says he "stole it from Krillin".
Both Majin Buu and Kid Buu were able to copy the Super Kamehameha after only seeing it used once. He also (according to Goku) copied Vegeta's Continuous Energy Bullet (though it is unknown how Goku would know this, since it is a technique that most characters capable of manipulating ki can use).
Gotenks' Bam Bam technique is to copy another person technique. It is used to copy Mr. Satan's Dynamite Kick on Super Buu, as well as Yamcha's Wolf Fang Fist and Tien's Volleyball Fist on Aka in Dragon Ball: Yo! Son Goku and His Friends Return!! As a Super Saiyan 3, Gotenks mimics Super Buu's Vice Shout in order to rip dimensions so he and Piccolo can escape the Hyperbolic Time Chamber.
Appearances in Video GamesEdit
Mimicry is Majin Buu's special ability in Dragon Ball: Zenkai Battle Royale: after seeing an opponent's long-distance energy attack, he can use "Kamehameha" to replicate it, and after seeing a close-range physical technique, he can replicate it using "Buu Rush".
