OK so there's a game villain tournament thread but I don't see it as the same thing. Especially since you're not supposed to post e.g. comic book villains that appear in games there etc. I searched "Boss" but didn't see any thread about this. So yeah, what are your favourite boss battles in any game? For me, many of the boss fights in Spider-Man: Shattered Dimensions are up there (Electro, Hammerhead, Juggernaut, Goblin) as well as Anti-Venom in EoT (though I haven't played it :/ ) Also, the boss battles in the first three Crash Bandicoot games are some of the best too (Cortex in any game, Tiny in any game, Mr. Trophy etc.). Same goes for the God of War bosses (Ares, the fat Medusa in GoW2, Zeus in GoW2, the Sister of Fate, the Colossus of Rhodos or what he's called, Poseidon, Hades, Hermes, etc.) There are many more but these are the ones at the top of my head.
