Simply post your favorite spell/magic from KH2.
My would be.
1 Thundaga (reason: kills many Nobodies on 1 hit =D)
2 Barrier (reason: blocks any attack, im not sure the name of the spell is barrier tho..since i only used that spell on FM+)
3 Curaga (reason: heals sora...and others in his team 100 %)
