It's just a case of powercreep in multi sequel games.

Playable character typically gain more and more power each game.
So the next game has to acknowledge it and give stronger enemies to fight. Eventually you end-up needing to fight god, then the boss above god.

(unless it play the RESET CARD but that's just as silly)
