Ryūken

Ryū-ken (龍拳, Dragon Fist) is Super Saiyan Goku's side special move in Super Smash Flash 2. Super Saiyan Goku transforms into a Super Saiyan 3 form and releases a dragon shaped projectile from his fists, resembling to Shenron. Also, the player cannot release another Dragon Fist until after the projectile has left the boundaries, but this was a "bug" that got fixed in the demo v0.8b. In the anime and manga, Dragon Fist Ryū-Ken also known as Ryū-Ken Bakuhatsu (龍拳爆発, Dragon Fist Explosion) or Chō Ryū-ken (超龍拳, Super Dragon Fist) is the only technique Goku comes up with completely by himself. He begins the attack by making a straight fist faced at his enemy, then once his fist, along with his own body, exits the stomach or chest of the target, the energy will explode out into the form of an enormous golden dragon which bears a great resemblance to Shenron and then finally collides into the target, possibly destroying it in its path or leaving a gaping hole, hence the name, Dragon Fist.
