Need help coming up with a name for my golden age Superman inspired superhero

Writing a story and my protagonist is a younger man who's power set essentially mimics that of the original Superman. No flight but can jump far, super strength, strength based super speed, and invulnerability.

I can't for the life of me think of a name for him though, everything I come up with just sounds like a superhero you'd see in cartoons cartoon.

Any help would be greatly appreciated. (Any design ideas would be nice too lol)
