The roster for Brawl was 35 characters strong, the largest in the whole series. It also marked the first time that guest characters from outside the Nintendo portfolio were invited, as Snake from Metal Gear Solid and Sonic the Hedgehog got their Smash on. However, despite the strength in numbers, the roster many have, at one point, been even bigger.
When Brawl finally released, savvy players accessed the game’s code via a disc hack and found files for seven unused characters, three returning from Melee in Mewtwo, Dr. Mario, and Roy, and five brand new characters in Dixie Kong, “Toon Zelda,” ”Toon Sheik” (huh?), and the team of Plusle and Minun from Pokemon. Now that we know about them, we really want to play as them… perhaps some of them will appear in the new game.
