Luigi is a classic major character and a deuteragonist of the SMG4 series, he is Mario's brother. Luigi is portrayed as paranoid and scared (Mainly to Boos), He normally is abused by Mario a lot while in older bloopers Luigi did the same back. He is treated as a joke and is commonly abused by a lot of people. In Luigi Labyrinth, he is portrayed as a villain and tried to rule the world for payback. Despite that Luigi cares about his friends and in later episodes they don't treat him as inferior and treat him equally though they may make fun of his cowardice.
Rather than being a lovable coward sidekick to Mario, this Luigi is often portrayed as a paranoid and easily scared manchild (mainly afraid of Boos), who was often humiliated by his peers. While he did have awesome and courageous moments, they were normally very rare. He was commonly treated as a joke of bully-victim in a couple of bloopers, being called gay and someone who "nobody cares about". In SM64 Bloopers: Luigi Labyrinth, he became a villain who tried to rule the kingdom with Luigi Dolls. Despite the arguably cruel way he is normally treated, he is selfless and willing to commit for his friends.
Due to the events of SMG4: Deleted, he was sent to the Internet Graveyard due to the Luigi Doll altering his unknown origin video, having the doll replace Baby Luigi as Mario's brother. However, he and his friends were rescued by his brother, Mario in SMG4: A Totally Normal SMG4 Episode.
Luigi is no different from his canon counterpart, Luigi has a long-sleeved green shirt, blue overalls with yellow buttons, brown gloves with white gloves, green cap, brown hair, black mustache and blue eyes. He is taller than Mario who is taller than Human Meggy who is 5'2".
Luigi is one of the kindest and most charismatic members of the cast, he loves lending a helping hand. He normally isn't violent and tries to use common sense to solve his problems. He can get very nervous and very scared, he is a coward and can get scared by Goombas who are far weaker than him. He is shown to be stupid at times doing the wrong thing when it's clearly obvious what he should've done, he cares about his friends very much as shown in Modern videos. Luigi also can get angry to a point where he can get extremely pissed. Luigi is shown to be gay though straight with Daisy meaning he might be bisexual. Luigi also celebrates too early, he is very close to his friends that he would commit suicide just to save his friends.
