To Reclaim My Title - Villain SMG4 AU

The deadliest villain of the Mushroom Kingdom. The man who had fallen from his throne, with many failed attempts at trying to reclaim it, has got his hands on the YouTube remote, and is now completely unstoppable: SMG4. He can finally enact his revenge on the man who pushed him so far down into a spiral of depression, suicidal thoughts, and obsession with revenge: SMG3. Granted, he didn't really do it on purpose, but how was SMG4 supposed to know that, by actually talking to him?? Yeah, right. Real men don't talk about their issues and be direct with their feelings, they try to destroy the world and kill all their enemies instead. Here he is, the fallen YouTuber, who has come back to reclaim his title.
Here are some of the What-If questions I've had since 2021. What if SMG3 and SMG4 had each other's personalities? What if SMG4 was the one to be pushed to villainy? How would the Arcs have gone? Just how different would the YouTube Arc have been? Now, I'm finally going to be writing out my answer. I'm more of an artist than a writer, but I think I'll have a better time writing this versus drawing. I can always do that later. Do note: I am an SMG34 shipper, so if you don't like that then I recommend not reading this, since that ship will probably appear later on in this fanfiction.
