SMG4/Relationships

Mario
Mario is one of SMG4's friends; however, the two are prone to incessant fighting, even over minor issues. SMG4 frequently gets fed up with Mario's antics and stupidity, often insulting the plumber with homophobic slurs. Mario also has problems with Glitchy; for example, he finds SMG4's SM64 bloopers unnecessary and stupid, oblivious to the fact that his existence and well-being hinges on the production of these videos. Mario and SMG4's hostility towards each other has practically been monetized with the annual War of the Fat Italians.

Mario and SMG4 seem to have a love-hate relationship, but they remain friends for several reasons. SMG4 has been shown to care deeply about Mario, and after a particularly tough ordeal will ask the latter for forgiveness. Mario will also get sappy during these scenes, but his emotions have often been used or discarded for comic relief. In short, Mario and SMG4 are perfectly fine with one-another when something crazy isn't happening.

Luigi
While he has sometimes called out on Mario for abusing Luigi, SMG4 very rarely has interactued with him, often hanging around with Mario instead. Howsever, on the rare occasions that they do, SMG4 often treats Luigi in the same condescending manner most others do. Howsever, despite that, he seems to care for him, as the tried to murder Mario with a chainsaw after that one killed Luigi in Luigi Wants to Build a Snowman, and the stated in Meet the Luigi. that he feels bad about him being always beaten up and forgotten.

Waluigi
Before the The Waluigi Arc, relationship with SMG4 seems to have relatively neutral, varyng from blooper to blooper.
