|~ Mr. L's catchphrase.|
|~ Another catchphrase of Mr. L.|
Mr. L is an antagonist in Super Paper Mario. He's the evil alter-ego of Luigi. He is a boss in World 4 and World 6 in Super Paper Mario. He was originally Luigi, but he later got brainwashed by Nastasia and he was told to defeat Mario and his friends once and for all, but as
Mr. L also has a robot that he calls Brobot, because it is a robot modeled after Luigi. Later in Super Paper Mario, after being defeated by the heroes twice, Dimentio kills him. he appears as his normal self in the Underwhere. He was reunited again by Mario to help his friends out.
He also technically serves as the final boss, as Dimentio brainwashes Luigi during the final battle, then fuses with him and the Chaos Heart. However, Super Dimentio is defeated, Luigi is returned to normal and the day is saved.
Mr. L can, from different points of view, be seen as both an upgrade and downgrade of Luigi. Unlike Luigi, he is very brave and confident of himself. He also seems very smart, seeing as he built Brobot all by himself. However, Mr. L has too much confidence, resulting in an egotistical behavior with many flashy poses. And all of Luigi's kindness and humbleness is gone. He also uses any positive attributes he gained from being brainwashed for evil deeds, which the real Luigi would never do.
- In Super Smash Brothers Brawl, he is mentioned in Paper Luigi's trophy, but as Mister L instead.
- His stats: Max HP is 40, Attack is 3 and Defense is 0.
- In the Flopside Pit of a Hundred Trials, Shadoo copies all of the game's main four heroes. However, when he copies Luigi, he actually has Mr. L's silhouette instead of Luigi's.
- Throughout the game, Mr. L is treated as an outsider by most of the minions, but Dimentio takes special interest in him, aware of his power and manipulating him to serve his own evil plans.
