Yes, the 2 troubled friends are seeing who are more awesome.
Plot
In the pre-intro scene, Mario tells SMG4 that he's better than him, and does the "FU" meme. In the castle, SMG4 gets mad at Mario for stating he's better than him. They soon have a series of contests to see who's better. After the sixth contest, Mario and SMG4 keep fighting about who is the most awesome again, when Starman3 comes into the scene. He tells them to stop fighting but instead gives Mario the satisfaction of shooting SM3 far away. X comes into the scene and then tries to work out the conflict, but ends up getting blown away too. After the eighth contest, Mario and SMG4 cooperate in "a duel to the death", but was actually a game show. X is the host and is about to start. He asks the first question to SMG4, which is what was the color of his underwear. SMG4 didn't have an answer, so X shoots him. He asks Mario what has no wings, but can fly. Mario answers Bowser, but X shoots him and deems Starman3 the winner. Mario and SMG4 then end up in an arena-type place, where they fight again, SMG4 manages to beat Mario up. Then Mario suddenly ends up in the volcano where X appears and tells Mario that SMG4 is in trouble. SMG3 was going to drop SMG4 into the lava. Mario decides to go and save SMG4 from a fiery death. Soon after all that time, Mario reaches SMG4 and punches SMG3 off. SMG4 thanks him for saving his life, but Mario pushes him off too. Mario then celebrates that he is the "awesome one". X then gives a speech on why they should stop fighting. Mario then shoots X away. Mario then says "What?" after SMG4 saw him shoot X away.
