Heavy Elbow is one of Goku's special moves. By default it is bound to quarter-circle forward and light, medium, or heavy attack. This move can be performed in the air or on the ground. Goku will simply rush forward, his elbow in front of him, and ram into his opponent. The light version starts up fastest and does the least damage. The medium version causes Goku to reel back before charging forward, and does more damage. The heavy version is much the same, however, it does the most damage and starts up quicker. The medium and heavy versions of this attack will act like a standing heavy attack, or the third hit of a light auto-combo, where it will knock the foe away. The light version does not have nearly the same effect.
