[Marvel][DC][The Boys][Fate][Arcee, 2B, Wanda, Diana][No Natasha][I Don't Eat Beef][Soldier Boy? No, Homelander!][Daily Sign-In System]

The protagonist's skeleton and body configuration has been modified, enhanced only by adding metal-based special properties, always remaining his own body.

"Come, general, may I have your name?"

"I am the son of the All-Father Odin, God of War-Leon Stark Odinson!"

"When you're away from home, your identity is what you make it," said Leon, the golden-haired, green-eyed Super Saiyan whose body erupted with golden aura, with deep purple electric arcs flickering in and out.

Memories dormant, transmigrated into Marvel at birth, Leon becomes the fraternal twin younger brother of Iron Man Tony Stark. In the year both turn 38, just as Tony is kidnapped by the Ten Rings, Leon is arranged to have a lucky break, accidentally completing a hidden task, unlocking the Daily Sign-In System, awakening past-life memories, and starting to take over the plot. He starts with the Soldier Boy template + super self-regeneration, instantly becoming a super Deadpool. But Leon remains humble, feeling he is not strong enough. While clocking in and collecting waifus, he diligently signs in, occasionally drops by neighboring universes for a visit. In the end, he didn't go bald, and he became stronger.

Iron Man armor?

"Sign in, Starlight template!"

Kryptonian Superman?

"Sign in, Super Saiyan!"

S.H.I.E.L.D. agent Natasha?

"Sign in... wait! What's going on??"

PS: The main world is the Marvel Cinematic Universe, so the power levels won't be too outrageous; mainly referencing the Thor/Hulk tier. Other worlds will be visited randomly.
