In the storyline, Gen often uses the Zan'ei in his assassinations; the only person known to have survived the technique is Akuma during Gen's encounter with him in the storyline of the Street Fighter Alpha series.
DescriptionEditExecuted by performing two quarter-circle forward motions and pressing punch, Gen draws back in preparation for the attack, then suddenly moves forward across the screen in an instant with his index finger, middle finger and thumb in a claw-like configuration.
Gen dashes through the opponent, and if the attack is not blocked, when Gen stops, the opponent will suddenly suffer 6 hits of damage consecutively. The distance Gen travels before stopping is determined by the punch button pressed.
Gen recovers from the dash just in time for the opponent to take the final hit and be sent flying; in the Street Fighter IV series, this is an ideal setup for either of Gen's first two Ultra Combos (Zetsuei or Ryukoha).
