Executed by rapidly pressing any punch button, E. Honda launches a flurry of thrusting palm strikes which move faster than the eye can see, projecting an afterimage of the user possessing multiple arms.
This move is very useful for both ending combos and approaching the opponent safely due to Honda moving forward a bit during the move's execution in all appearances, though it leaves Honda widely vulnerable to counterattack if missed or blocked.
In early versions of Street Fighter II, the Hundred Hand Slap did a lot of damage per hit - in Street Fighter II Turbo, each hit of the Hundred Hand Slap was worth 1/6th of an opponent's health bar. This, coupled with the ability to move in those games, made him into something of a "steamroller" (which also applied to other moves similar in nature in future games). In such application, the move could be performed infinitely, as long as the Honda player kept tapping the punch button without being hit at all.
In Street Fighter V, this move is one of E. Honda's safest special attacks. While the damage inflicted is minimal compared to Sumo Headbutt, it can be difficult for his opponent to punish. The Light version leaves E. Honda +2 on block, while the Heavy version puts him at -2 on block. He can also cancel into his V-Trigger or his Critical Art on the third hit of this attack.
Later games abandoned this in favor of a strength-based distance mechanic:
