Most hated Maplestory monster?

I also hated the fake geist balrog. On my low level dexless sin, I was at Amoria without any pots (it was level 1x-2x, can't remember). I was trying to pass by Purple Plains 2 and then the Fake Grog was there, and it kept killing me. I clicked OK to revive, but it killed me again. Revive, die, repeat.
