My Days as a Shapeshifting Mage in the Superhero World

Mitchellson Percy dies unexpectedly and transmigrates into a superhero world teeming with villains, where heroes are as common as dogs and ordinary people reincarnate at the speed of sound.

Good news: He has a System.

Bad news: It's a knockoff of the cute god next door: the Shape-Shifting Percy System.

Mitchellson: ...Careful, or the neighbors will sue you for plagiarism.

System: It's fine. We don't use their stuff. Respecting originality starts with me.

In other words, Mitchellson has to make all those cards himself.

Mitchellson is already looking for a rock big enough to let him bash himself to death.

System: This System follows the principle that the more clothes you wear, the more abilities you have, and the more fabulous your clothes, the stronger your magic.

So, chosen boy, how about a degree in magical fashion design?

Gotham City, an ordinary night.

After turning on the Bat-Signal, Gordon turns to look at the person who has arrived.

"What the f, "

Nearly blinded by the light, Gordon hurriedly pulls out a pair of sunglasses and puts them on. Expressionless, he looks at the man in front of him, who is glowing of his own accord.

Then he looks at Batman, illuminated beside him so thoroughly that even in the darkness, nothing is hidden. Every pore on his face is crystal clear.

"Are you insane? Why bring a little sun along on patrol?"

Batman: ...

New York, under attack.

A gigantic figure flies into the sky. An elaborate pattern rises from the ground and forms a transparent dome protecting all of New York.

Iron Man's faceplate flips open. He looks at the figure, thousands of meters away but still so dazzlingly enormous, then nudges Strange beside him.

"Old friend, you lose."

Whether it's magic or fabulousness, you've been thoroughly beaten. How can you be so poor when you're both magicians?

Strange: ...

Superman and the others are invited to a gathering at Wayne Manor.

Superman watches Damian ride past on a lightning-wreathed bull.

He looks at the group of elegant men relaxing beneath a tree next door, teacups in hand.

He looks up at the beautiful women dancing gracefully in the sky, scattering countless flower petals.

Finally, he looks at Bruce, who has come out to greet them. "Bruce, is your place... a little small?"

Bruce: ...

Warnings:

1. The pairing is set in stone: Batman is the love interest.

2. A plot-free, anything-goes story that may be full of plot holes. I'll write as I go.

Theme: Saving the world is everyone's responsibility.
