American Comics: From the Start, I Sign In to Get the Sharingan

After transmigrating into the Marvel Universe, Roy became a weak Mutant who was used for experiments.

Fortunately, Roy awakened the sign-in System and obtained the Copy Sharingan from the start.

Ordinary Mutants have only one superpower, but Roy has countless abilities.

Ancient One: I thought Doctor Strange was a magical genius. It wasn't until Roy appeared that I learned what a true genius was.

Apocalypse: As the progenitor of Mutants, I possess all Mutant abilities. It wasn't until I met Roy that I realized he's the real daddy.

Phoenix: I'm only a Level 5 Mutant. Roy is the king of our Mutants. He's the equivalent of a Level 10, or even Level 100 Mutant. He's the god of Mutants.

Odin: From the moment Roy entered Asgard, he was stronger than me. I feel like I should bow down and worship him.

Dormammu: The moment Roy glanced at me, he became stronger than me. When it comes to being outrageous, I bow to Roy.

Thanos: You won't believe this, but Roy glanced at me, acquired my Titan physique, and beat me like a dog. Boss Roy, let me follow you from now on! I can farm, and I can snap my fingers.
