Ramuh

Ramuh is one of many summon spells in the Final Fantasy series. He always has the lighting element associated with him. To my knowledge he has never been a playable character and only a support role as a being to summon during combat and/or an item that grants magic spells. Ramuh always appears as on elderly man with a white beard and a staff of some sort. It's in Final Fantasy XI where he makes his most drastic appearance change.
