I was thinking of making a super enemy for PSIV that would be an optional challenge. It's obviously in the early stages, but here's what I have so far
RULAKIR (he miraculously survived the events of PSIII and ended up back in Algo through Aron/time warp)
HP: 32767
Attack: 99
Defense: 80 (Chaosbringer at 42 is the highest in the game except for Zio the first time)
Magic defense: 50
He gets two turns to your one. Every other turn, he uses Zio's magical barrier which needs to be broken by the Psycho Wand. He knows Megid, Diem, Legeon, and, um...help me out here.
