He introduces himself as SuperLuigiGlitchy4 and SMG4 question the similarity in their name. Mario started to piece thing together and believes that they are both married. When SMG4 asked SLG4 to stop calling him "bro", Toad point out that they are probably brothers (He is disappointed to not have the DUN DUN DUN sound effect). 2h later, Dr. Mario tells them that SMG4 is the father and after an awkward moment Dr. Mario reveals that that result was for Toad (who runs away after hearing this) and confirm that they are in deed brothers. As Luigi looks at SMG4 and SLG4 happiness, he asked Mario that they should be more like this which Mario decline and punch Luigi for fun. SMG4 asks SLG4 what to do, and they both decide to do a montage. Later, Mario, SLG4 and SMG4 went to buy supplies for the castle. SLG4 threat bad Mario and Mario noticed a change of color in the text of SLG4. SLG4 told Mario that SMG4 made a mistake when he invited him. When SMG4 arrives due to the screams, Mario tells him he saw a hot girl but SMG4 states that it was in fact a man. Later, at Bob-Omb Battlefield, Mario tells Luigi that SLG4 is mean at him (flashback of SLG4 doing bad things to Mario). When Mario tries to spy on him, SLG4 found him easily and beat him up. Later, at the castle, SMG4 tells Mario that he is does not believe him because he can' believe that his brother can be evil. Mario tries to convince SMG4 that SLG4 is attacking Starman, but he was in fact dancing with him. SMG4 then left giving SLG4 the opportunity to pursue him. When Mario escaped him, Luigi tells him to stop crapping in the hallway. Mario tells Luigi that he has to get rid of SLG4 and reminds Luigi that he can get rid of him to. Mario later hired Bowser to kill SLG4 in exchange for a Justin Bieber magazine. When SLG4 arrives, Bowser feared him and jump off the stage. SLG4 tells Mario that he hates plumbers and punches him. Mario sad, goes into an alley and find in a trash, the photo of SLG4 and SMG3 together. With that evidence, Mario returns to the castle and attempt to expose the truth to SMG4 but accidentally told it to SLG4. Mario tries to escape on multiple door but SLG4 blocked him. Mario tells him to watch out but SLG4 doesn't fall for the ruse but got crushed by a Thwomp. When Mario found SMG4, he is caged by SLG4 and while he is talking about how pleased his master SMG3 will be, Mario broke SMG4 out, and they both run away. Once outside the castle, SMG4 asks Mario a solution, but he wants an ice-cream. After SMG4 told him to focus, Mario had a plan and it requires using the outside cannon. SMG4 tricks SLG4 into getting inside the cannon and Mario manipulate the cannon trajectory and lauch SLG4 to the sky where he explodes and died. The two then went for a burger.
