Our version of the Focus Attack that originated in SF4.
It's a chargeble attack which at its maximum becomes unblockable and smashes the opponent away, and on kill causes a wall-break.
A fully-charged FA that doesn't kill will knock the opponent out and when they get back up, are in a dizzied state.
You're also able to dash cancel out of it while you're charging or as soon as it hits (with the exception of the fully-charged version),
allowing you to rush in and start a follow-up attack. We call this Focus Attack Dash Cancel or FADC for short.
You cannot FADC if your Focus Attack was blocked by the opponent.
The charge has a 1-hit armor, meaning you can absorb one hit from the opponent.
If you're hit a second time, you'll get knocked out of the move.
An extra feature added to this move is the Projectile Reflector;
by timing it right you can use the Focus Attack to swat back single hit projectiles fired by the opponent.
In later iterations of the game, you can hold SP+SK after a knockdown to perform a Focus Attack immediately on wake up.
