I’m pretty sure the eternals of Hyperion’s earth are different from the 616 ones. So probably not.

Well I've read somewhere and it said every version of Hyperion is an Eternals but I just don't know is it true or not

Almost every version of Hyperion is Eternal but not every Eternal is like Hyperion.

Also, his weakness is not Vibranium but Argonite.

He also has a weakness to magic, such that he is powerless in mystical realms.

Sorry mb... But thanks for the info

Is there any exact reason.. why? Or it just for the parallel between superman?

^ The latter, I believe.

It's the parallel with Superman.

And not every single Hyperion in the multiverse is an Eternal, the vast majority are Eternals tho.

Earth-616 Hyperion is a clone of an alien from a planet of the Microverse.

Earth-712 Hyperion is an Eternal.

And the one with the radioactive symbol on the belt is an Eternal too, from another universe and was brought to Earth-616 by AIM.
