Okay his kind isnt that strong. But seeing how he kicked one of the strongest viltrumites in the face, probably makes them the 2nd strongest race in potentially competing them. They just dont get the cool shit, every single race that looks human has.

Lets say idk it takes 15 of them to take down a viltrumite. They are kinda warlike. And the guardians of the globe can take omni man with recognizing the current threat. Plus the dudes down there probably have weapons that can pierce them, its just there killing each other.
