Executed by performing a quarter-circle forward motion and pressing punch, Alex moves slightly forward and delivers an open-palm horizontal chop to the opponent. The amount of time the move requires and the distance Alex moves forward are determined by strength of the punch button pressed: heavy punch takes more frames to execute and moves an entire pace forward, whereas light punch barely moves forward at all and executes quickly. There is also an EX version, but this sends the opponent roughly 2/3 of the way across the screen on impact.
The Flash Chop can stop fireballs, and when it hits the opponent it spins them around, meaning that they are facing away from Alex for a second after it hits, allowing him to set up combos. The heavy version can cancel into a backdrop suplex, executed by inputting the Power Bomb motion right after a hit.
Because of Alex's wrestling background, the move can be seen as an homage to the "Flair Chop", a similar attack made famous by the WWE wrestler Ric Flair.
In Tatsunoko vs. Capcom: Cross Generation of Heroes, The heavy punch version can be charged, and when fully charged it becomes a Machine Gun Flash Chop with 20 rapid-fire flash chops following the initial strike. If it is fully charged, the move becomes unblockable. However, if you charge the move fully you cannot immediately follow-up with other attacks due the distance the opponent is sent fly on impact.
Through the use of partner assists, this can easily set up for resets.
