Krillin

Krillin (クリリン Kuririn) Krillin first appears in the original Dragon Ball series when he arrives at Master Roshi's island to become his apprentice. Krillin did this because he wanted to become a powerful fighter that could impress the ladies. Originally, Goku and Krillin were rivals, with Krillin using dirty tricks to outdo Goku during training, but eventually they become close friends. At finishing their training, Roshi has the two compete in the 21st World Martial Arts Tournament. Krillin makes it to the semi-finals (after defeating Bacterian in the quarter finals), but is defeated by Jackie Chun, who is really Roshi in disguise, preventing his students from becoming arrogant with too many victories.

Krillin continues to train with Roshi while Goku is collecting the Dragon Balls and helps him retrieve one of them, at which point he fights General Blue. He also participates in Baba's tournament with Goku, Yamcha, Puar and Upa, but loses in the first fight to Fangs the Vampire. 3 years later, Krillin enters the 22nd World Tournament. Again he makes it to the semi-finals (defeating Chaozu) but loses to Goku. Soon after however, Krillin is killed by a henchman of King Piccolo, known as Tambourine. After Goku defeats Piccolo, Krillin is revived by the Dragon Balls. Another 3 years later, Krillin enters the 23rd World Tournament. This time however, he only makes it to the quarter-finals, losing to Piccolo Jr.
Krillin has many abilities including, super-strength, super-speed, and the ability to fly using his chi energy, also known as Bukujutsu. His main techniques include the Kamehameha, an attack he learned from Roshi, which enables him to emit a powerful chi energy blast from his hands. Kakusandan, another chi attack, involves firing two blasts, one from each hand, and merging them before directing the blast above an opponent where it will break up and rain down on them, he was only seen using this twice -- the first time was very successful as he managed to wipe out three Saibamen with it. He has also been known to use the Tsuihikidan double-chi-blast attack. From Ten, he obtained the Taikyoken (or Solar Flare), an attack Krillin is capable of using to blind his opponents, sometimes used to make a quick escape. A technique unique to him is the Kienzan (which is also known as the "Destructo Disc") , which he does by putting his hand in the air and creating an electric floating disc, using it to slice through his enemies, he only managed to successfully do this to an enemy three times, first when he cuts off Frieza's tail, when he cuts off Bio-Broly's head and also when he cuts Kid Buu in half, but the monster quickly regenerates. Krillin can easily manipulate his energy which allows him to maneuver at high-speeds as shown in his fight with Piccolo, the Saibamen and against Garlic Jr. Krillin has also used the Zanzoken after-image evasion technique, but on only two occasions in the anime version. In the anime filler, Krillin is also shown using the Multi-Form technique during the fight with Nappa.
