The custom ML3 Project

[Chaoxys]

In the game, there are points where Bowser is as good as dead, but Mario and Luigi trigger adrenaline rushes that cause him to not only recover, but grow to gargantuan proportions as well.

BTW Grey, after playing the game, most of Bowser's giant sprites are indeed tweaked resizes of his normal sprites. Trust me, I've beaten the game.

I know, I beat is the day after it came out.
I just needed one for size references, and so I could see any other details they may have been needed, like if they edited certain parts for finer details.
