Classic Luigi

Classic Luigi was a secret playable character in Mushroom Kingdom Fusion 2. He is a throwback to the original NES-era Mario.

Gameplay
If Classic Mario is selected with the fire button, he becomes Classic Luigi. Classic Luigi plays akin to how he did in the Japanese Super Mario Bros. 2 (Super Mario Bros.: The Lost Levels outside of Japan) and games following it by having a higher jump, but reduced traction and slightly slower speed.
