A bio-android created by Dr. Gero. He was constructed by collecting cells from powerful warriors such as Goku, Vegeta, Piccolo, Frieza, and King Cold. He can use the techniques of other characters (like the Kamehameha) and possesses Piccolo's regenerative abilities, allowing him to recover even if his body is blown apart. By absorbing Androids 17 and 18, he evolves from his Imperfect form to his Semi-Perfect form, and finally to his "Perfect" form. After reaching perfection, he hosts the "Cell Games" martial arts tournament to test his power, engaging in a fierce battle against Gohan and the others. Techniques: Kamehameha: Copied from Goku's cells. Famous for the clash against Gohan at the end of the Cell Games. Instant Transmission: Learned in his "Perfect" state after self-destructing and regenerating. He learned it by analyzing Goku's cells after Goku died in the explosion. Spirit Bomb: Inherited from Goku's cells; he claims he could use it if he wanted to, though he never does in the story. Tri-Beam: Tien's technique. Used in his Semi-Perfect form to pursue Android 18. Galick Gun: Copied from Vegeta's cells. Fires a powerful energy wave in Vegeta's signature stance. Big Bang Attack: Vegeta's technique. Used in the anime version of the Cell Games. Regeneration: His most troublesome ability, derived from Piccolo's cells. As long as the "core" in his head remains intact, he can instantly regenerate his entire body. Special Beam Cannon: Piccolo's ultimate move. Concentrates energy at the fingertips for a high-penetration beam. Bio-Extract Absorption: Absorbs the essence of humans through the tip of his tail to increase his power (primarily used in his first form). Cell Junior Creation: Only usable in his Perfect form. He spawns miniature clones called "Cell Juniors," who possess strength comparable to a Super Saiyan, from his back. Death Beam: Copied from Frieza's cells. Fires a high-speed beam from his fingertip; he used this to pierce Trunks' chest immediately after his resurrection. Death Ball / Supernova: A massive energy sphere Frieza uses to destroy planets.
