Appearance:
Gotenks is one of two fusions performed through the use of the Fusion Dance technique. He, along with Gogeta, the fighter created by Goku and Vegeta using the Fusion Dance, were summoned out of desperation to defeat powerful enemies. In Gotenks' case, his enemy was Majin Buu and later in the saga,he is to be used by Majin Buu as his main power source where Gotenks is absorbed heartlessly. Gotenks is seen a few times in Dragon Ball Z.
Abilities:
Gotenks' childish personality causes him to create many, many attacks, some of which are nothing special, while some deal hefty damage. Most of his attacks are only used once. He tends to give very basic moves complicated names. His habit of giving names to all his attacks (and subsequently only using them once), could possibly come from Vegeta, who has a similar, yet much less ridiculous, habit (Vegeta's most-associated attacks, such as the Galick Gun, Final Flash, or the Big Bang Attack, are each only used once in the manga). This habit is less apparent in the anime, as Gotenks and Vegeta tend to use those attacks more than once.
