From becoming a superman to becoming invincible

Leon, who traveled through Marvel, was adopted by Howard Stark. At the age of eighteen, he awakened to the Kryptonian physique and the ability to travel through time and space. From then on, he ran wildly on the road to becoming stronger.
Tony: Oh my God, you can become stronger just by basking in the sun, and you are going to learn magic? Oh! What is this? Chinese kung fu that grows a planet inside the body?
Superman: They are both Kryptonians, but I feel like I have been living in Leon’s shadow!
Batman: Damn! He took all my kryptonite before I even shot him Ruined!
When the villains created a large number of kryptonite missiles and prepared to fight Leon, Leon flew outside the earth, lifted the earth with one hand and threw it easily.
“I’m still not strong enough, so I have to find another world to retreat in,” he said.
