I might've seen this on a few other threads, but I notice there wasn't too much in-depth info about it, so I decided to post one here. Anyways, here's what I'm thinking for the character: Proposed Suggestion: Music: (NES) (I'm still thinking of how the SNES version of it work, but would probably have stuff from Super Adventure Island. As for the Gameboy version, the soundtrack for Adventure Island 2/3 is more or less the same) Selected - Adventure Island 2 Stage Clear Overworld - Adventure Island 3 Coastal Clash or Adventure Island 2 Plains Underworld - Adventure Island 2 Caves Underwater - Adventure Island 2/3 Underwater Bridge - Adventure Island 2 Cliffs Peaks - Adventure Island 2/3 Forest Night - Adventure Island 3 Thunder Clash or Adventure Island 2/3 Dark Forest Castle - Adventure Island 2 Final Level or Adventure Island 2/3 Dark Forest Boss Battle - Adventure Island 2/3 Boss Entering Pipe - Adventure Island 2 Overworld Underground Bonus - Adventure Island 2 Bonus Area Sky Bonus - Adventure Island 2/3 Clouds Invincibility - Adventure Island 2/3 Invincibility Hurry! - Adventure Island 2 Eggplant (This repeating over and over again) Death - Adventure Island 2 Death Game Over - Adventure Island 2 Game Over Stage Clear - Adventure Island 2 Stage Clear Castle Clear - Adventure Island 2/3 Boss Defeated Ending - Adventure Island 2 Credits Sprites: His Adventure Island 2/3/4 sprites (Almost identical). The "throwing" sprite would be if he were to throw an ax or a boomerang. If Gameboy sprite, then he would simply be grayscaled. If SNES sprite, it would have to be slightly custom as his Super Adventure Island sprite is significantly bigger than his NES sprite. If he gets hit, he'll trip. Also, like the Mario Brothers, Master Higgins can swim too. Powerup: No Mushroom - Master Higgins cannot do anything OR Master Higgins can only throw axes. (Depending on if he's too underpowered as a "Small" form or not) Mushroom - Master Higgins can throw axes OR he can throw Boomerangs now OR both (Attack for the ax, special for boomerang) Fire Flower - Master Higgins goes on a dinosaur. The first three of these would probably work the best because a flying pterodactyl would make the game a bit broken. Red one breathes fire, blue one whacks some lightning from his tail. Purple one is perfect for water levels. They'd be symbolized by these cards. And no, I don't think the skateboard will fit in with Super Mario Bros. Here's a gameplay video (For anyone unfamiliar with Adventure Island).
