So after beating the game, during the credits, there's an image of The Commando. After beating it with no matter who - you get The Commando standing there. My suggestion is to make a pixel art for every character in-game, and then - when you beat the game with that specific character, he'd be the one you see during the credits roll. Now, I do get that these images are not so easy to make ( If I knew how to make pixel art I'd post them here regardless of whether or not they'd be added in game) , and that The Commando is like "The Face" of the game. HOWEVER! I do think that every character deserves a place during the credits.
