Hmm, I guess that's why in the GBA version they added Omega MK2 and Neo-Shinryuu

But seriously, almost all Hyper bosses are slime... FF8 Omega, I solo'ed with squall without holies, though I did get 3 lionhearts in a row LOL!

If you are using a Snes emulator, try the GBA emulator and fight Enuo, Omega MK2, or Neo-Shinryuu
