What happens when someone takes the games RimWorld and Minecraft along on their adventures between worlds and keeps gaining all kinds of mods?
In Saiki Kusuo's world, Mo Huan gets the Superhero Mod, puts on Batman's effects skin, and teams up with his insignificant sidekicks: Ying, wearing a Robin skin, and Paimon, wearing a Superman skin. Together, they become superheroes.
"Hydra, you cut off one head and... What, you call yourself Claw? Whatever. As long as you give me experience and loot boxes, it's all the same to me!"
In the world of JoJo's Bizarre Adventure, Mo Huan gives Jotaro Kujo a Stand called Heavy Bunny 19c and stages a grand theatrical production from behind the scenes.
Mo Huan: "Wake up, Jotaro Kujo. I'm a Terminator from the future, here to find the savior... Wait, I don't mean you. Not the black-haired one, the blonde one! Take this Heavy Bunny 19c. With it, you can defeat all evil. Now go find Ying for me!"
"...Wait, what is this? A blonde vampire? Is this Ying too?"
Really, it's just the multiverse journey of a game player who lives for fun and wants to help Ying get home.
