Boar Attack (イノシシアタック) is a basic attack used by Gotenks. Gotenks charges with explosive ki surrounding him, speedily dashing straight to the enemy with the force of a boar, and head-butts him with all his might.
The Boar Attack is part of the continuous stream of attacks that Gotenks uses in his base form during his battle against Super Buu in the Hyperbolic Time Chamber. In the anime, the technique is named "Charging Mad Bull Attack" and Gotenks does not succeeded in hitting Super Buu with this attack, as opposed to the manga where he hits Buu in the stomach.
This move appears as one of techniques in Butōden video game series, as one of Super Saiyan 3 Gotenks' super attacks in Dragon Ball Z: Supersonic Warriors 2, and as an regular charged strike in the Budokai Tenkaichi series. In the Raging Blast series, it is one of Gotenks' (any form) signature attacks. In Dragon Ball: Origins, Ox-King uses an attack very similar that he can repeat up to three times in a row.
