I DID.

FERAL CHAOS IS NOW MINE TO CONTROL.

OMG I ACTUALLY PULLED IT OFF.

TEAM (MOSTLY) GIRL POWER BEAT 000.

SQUEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

My thanks to:

Kain Highwind (who did more damage than I expected in the first round and showed that certain attacks can be dodged)
Yuna (who successfully whittled down FC's health to way down the halfway mark)
Lightning (who did her best, although with her attacks it was difficult to trap FC and keep him trapped)
Cloud of Darkness (who despite that her available attacks were the basic ones, managed to damage FC quite a bit, particularly with Anti-Air Beams)
Terra Branford (who finished him off and won the battle)

I reiterate:

SQUEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

What kind of attack though? BRV? HP? BE SPECIFIC MEME!!!
