I mean he doesn't have to earn his power from having a relative theme (like Thor being a Norse God of Realms) or having to earn them personally (like Darkseid absorbing power from Gods). To me a better theme would be that he a strong and smart alien that has to be kept up with not that he's unstoppable. I mean they give the guy infinite personal strength but make him also have overpowered technology and planning, the guy is just mary sue bullshit where they have to make him incompetent at the last minute so he can get macguffin'd.
