Luigi

Luigi is Mario's brother and a main character in the SMG4 series.

Personality
Luigi did not change much from how he is in the Mario games, still being the shy and cowardly brother to contrast with Mario's bravery and courage (or in this case reta$%#tion and obesity). He can be considered to be one of the most normal characters in the show because he doesn't have any weird attributes or do any weird things like Bowser reading about Justin Bieber or Mario streaking. He is also very caring for his friends and is constantly telling them not to fight and instead to be nice to each other, but it doesn't work and it causes them to think he is gay. He is logical in situations and usually doesn't make any stupid mistakes like Mario or Bowser. Luigi has been known to do very unusual things at times, which Dworlock likes to think of as him using the power of his inner Weegee. For some reason, there are large Luigi dolls in the show which SMG4 calls "Weegee Dolls" that have appeared in many episodes throughout the series.

Relationship with Mario
Luigi likes to hang out with Mario because they're brothers and they go on many adventures together, however Mario has been known to not be nice to him. Mario believes, like others, that Luigi is gay because of how nice he is and mocks him for that, also calling him a coward and scared of everything, sometimes going as far as saying that he is not his brother. Despite his mocking, Luigi still loves Mario (as a brother) who is essentially his role model as the big brother in the relationship and therefore becomes very sad when Mario disrespects him. Luigi never gets revenge because of how nice he is and will always be picked on by Mario, but only tries to make the relationship stronger and better than ever before.
