Charge Power Punch, or Dragon Fang (ドラゴンファング Doragon Fangu?) in Japan, is an unblockable attack used by Marshall Law and Forest Law from the first game onwards. Lee Chaolan can also perform this move prior to Tekken 4, where it was replaced with Death Touch, a left-handed variation of the move. Lee's version of the Charge Power Punch is called Silver Fang (シルバーファング Shirubā Fangu?) in Tekken Tag Tournament, which was the original Japanese name used in the earlier games.
Since the move's debut, it can be canceled with u,u.
In Tekken 2, the move's recovery frames were shortened, with Law and Lee no longer moving their arms around after completing the move. In Tekken 6, the move was given a new animation.
