Rollins will take the title off Yeetman.
That'd be OK.
My prediction (or at least what I'd do as the writer, given that Yeetman seems to be the most popular guy right now):
Cena stays for a bit. Trolls the other wrestlers and dares them to try and beat him. Can you rise to the occasion?
Cody searches his soul and is like, "I love John Cena too much. I couldn't strike him down, because he is my hero." Can Cody overcome his love and respect for the man who made him what he is today?
Whole bunch of faces enter the spotlight, join Team Cody, wrestle Cena. Nobody can touch the champ; one after another they fall.
Enter Yeetman. Yeetman and Cody share a special bond. Yeetman saved Cody at Wrestlemania XL, and helped Finish The Story. Cody gave Yeetman his Yeet catchphrase, and started Generation Yeet. Yeetman is champion, but he's still haunted by Gunther, he still has some self-doubt. Can I do it, uce? I'm just some kid from the West Coast. "Don't worry Yeetman" Cody says. "The power is inside you" or something, I dunno. Inspirational speech where Cody puts Yeetman over, and we establish that Cody is to Yeetman what Cena was to Cody.
Last chance to beat Cena. Yeetman steps up. Maybe it's a tagteam, Yeet and Cody, or maybe it's just straight Yeet. Either way, Yeetman pulls out all the superkicks he knows, defeats Cena, and the WWE Universe retains their history. Cena smiles, because that's what he wanted - he turned heel because he wanted to make sure that after he was gone, somebody would be able to rise to the occasion. Yeet was the guy, uce. He dug deep and proved he could do it. (alternatively, Cody turns heel to beat Cena, and Yeetman has to take over Team Cody, vowing to restore honor to the WWE)
Yeet can lose the title quick after that, because he's not really ready (workwise) for a consistent main card status, but he seems like the natural successor to Cody, AND he's got all the traits that made Cena, Cena.
That Cena match was so bad it killed the Pope.
lol, wonderful.
"Hey Snek, where were you when you learned the Pope died?"
Oh, I was just shitposting on the General Wrestling Discussion thread on Kiwifarms, and saw a joke about Cena's awful performance at Wrestlemania...
