Kaiō-ken Attack

Kaiō-ken Attack (界王拳アタック, Kaiō-ken Atakku, Lit. "World King Fist Attack") is 's side special move while in Kaiō-ken Mode in Super Smash Flash 2. Goku dashes forward with a red burst of energy, and exclusively in v0.7, proceeds to beat up the opponent with a devastating combination of punches and kicks.

Origin
In the Dragon Ball universe, this move is very different. Goku powers up to Kaiō-ken x3 as he charges at the opponent and roundhouse kicks them up into the air. Then, he flies up in the air and punches the opponent away. Next, he flies up over the opponent and down behind to double kick them further up into the air. Finally, Goku flies up into the air around the opponent and hook kicks them down into the ground, inflicting a huge amount of damage.

Trivia

 * Exclusively in Super Smash Flash 2 Demo v0.7, Kaiō-Ken Attack was very similar to the actual attack in the Dragon Ball universe; but they removed the combo of punches and kicks due to the excessive length of the special.
