Metal Luigi

Metal Luigi is the metal counterpart to Luigi. In Super Smash Bros. Melee, he appears in Adventure Mode, alongside Metal Mario once the player has unlocked Luigi. Metal Luigi makes the battle harder, because instead of battling one iron brother, the player has to battle two, who gang up on the player. Like Mario's metal counterpart, Metal Luigi is heavier than the normal Luigi like all of the characters. Metal Luigi appears in Melee as a boss when Luigi is unlocked. You need to go to Adventure Mode after that to witness his debut.
