Fudou Ken

Fudou Ken (Unwavering Fist) is one of Geese Howard's Special Moves in The King of Fighters series.

Description
Geese thrusts his palm into his opponent's midsection. The version can cause crumple stun, which can be used to extend combos.

In addition, this has multiple follow-ups:

Strategy
Known as the spiritual successor of his famed Jaei Ken, this rekka move is a straight palm that mostly serves as a combo extensions or super cancel filler special, though poking with the version occasionally can make for a fast check on your opponent.

On hit with the version, it combos from light attacks with only one possible followup, namely the O follow-up that can knock the opponent a good distance away, but causes a techable knockdown.

The version combos from heavies and has a slightly longer range. It has 3 possible followups, forcing the opponent into a high-low mix up with all leading to hard knockdowns. Generally, you want to combo the version with the A follow-up for super cancels, or the Un follow-up to end a combo and lead into either Raimei Gouha Nage or Raging Storm.

The version combos from light and crumples on the initial palm hit. It has the same 3 followups as the version, but with slightly altered properties.
