The final boss will be a surprise.
Rather than taking the usual path with Baby Bowser as the final boss, perhaps this game could shake up the endgame; perhaps with Kamek as the final boss this time, or even a new character. Or, if they're going for a safer choice, it could even just be adult Bowser again...but not as a Giant Space Flea from Nowhere.- Jossed - while Baby Bowser is still the final boss, Kamek is an optional Boss.
