Ryuugeki Ken

Ryuu-Geki Ken (lit. Striking Dragon Fist) is one of the signature moves of the Kyokugenryu Style, making its initial appearance in the Art of Fighting series and being a fixture of Robert Garcia in every game he's appeared in.

Description
The user swings their arm out and either throws out a surge of ki energy, or a full projectile depending on the user and the game.

In most cases, however, the move is almost always a short-ranged projectile. Which is often a very handy poke to use in the neutral.

Strategy

Trivia

 * As one might guess, this is another variant of Kyokugenryu practitioners what the Hadoken is to the Ansatsuken users of the Street Fighter series.
