From Becoming Superman to Invincibility

After transmigrating into the Marvel universe, Leon is adopted by Howard Stark and becomes Tony's younger brother.

On his eighteenth birthday, he awakens a Kryptonian physique and the ability to travel through time and space. From then on, he charges madly down the path of becoming stronger.

Tony: "My God, you can grow stronger just by basking in the sun, and now you're planning to learn magic too? Oh! What's this? Chinese martial arts that grow a planet inside your body?"

Superman: "We're both Kryptonians, but I feel like I've always lived in Leon's shadow!"

Batman: "Damn! Before I could even fire, he destroyed all my kryptonite!"

When the villains manufacture vast numbers of kryptonite missiles and prepare to wage war against Leon, he flies beyond Earth, lifts the planet with one hand, and casually tosses it up and down.

"I'm still not strong enough. I need to find another world and go into seclusion for more training," he says.

[In the early stages, he only possesses Kryptonian bloodline abilities. After traveling to the Devouring world in Chapter 117, he begins cultivating the Devouring (Starry Sky) techniques as well.]
