The Ninja is the main character in N and N+. The Ninja is the 100 bandage unlockable for the Xbox 360 version of Super Meat Boy. He also appears in Meat Boy (Flash). He has many advantages over Meat Boy. His ability is to sprint, which will make him as fast as most other characters, but if you press both dash buttons, he will tilt his head to gain an amazing speed, enough to surpass Naija, RunMan and Meat Boy for speedrun reasons. he's also very light, thus giving him amazing aerial control on fans and in mid-air. The only advantage Meat Boy has over him is that he doesn't slide up walls as far as Meat Boy. This makes him useless in wall jumping levels. It takes 100 bandages to unlock this character, which is 20 bandages in each world, except for Cotton Alley and The End.
His physical apperance in the game is an incarnation of how he looks in his own series, a black stickman with 2 red bandanas.
