So basically, I think the entire arc should start off with X returning to SMG4 to then find out he's a super meme guardian called SMGX. This gives X the power to turn to any avatar he wants to but presumably just stay on Mario's avatar. Then as the arc advances, the rest of the forgotten characters (Enzo, MCGustavo, FM, etc.) also visit SMG4, his new castle, and the rest of the crew. Suddenly, X misuses his power to turn into a cursed avatar and corrupt his own meme energy, and Enzo seeks his hidden revenge on SMG4. Finally, X and Enzo become so powerful that maybe they might end up being the antagonists of WOTFI 2024.
the arc shall be known as:
The Forgotten Arc
idk why i randomly just thought up of that lmao
