Mega Flare

Mega Flare (メガフレア) is a technique in Kingdom Hearts: Chain of Memories, Kingdom Hearts Birth by Sleep, and Kingdom Hearts Re:coded. Once used, the caster fires a fireball that, upon impact of an enemy, creates a blinding, screen-distorting explosion that heavily damages all enemies on screen.

In all versions of Kingdom Hearts Birth by Sleep besides the original Japanese version, Mega Flare's power is reduced. This is due to the Japanese version's Mega Flare being considered to be too powerful.
