Gilgamesh is a very cool side villain in FFV, and he's a lot better (and somewhat more reliable) GF than Odin in FFVIII. Odin riding with his horse and using Zantetsuken is still always a sight, especially in that one FMV in FFIX. Yojimbo was alright, and Zanmato is neat, but otherwise I don't think he's as great as Odin or Gilgamesh.
