Since Mark is half Human he should have a little shorter livespan than a average viltrumite. Omniman says Viltrumite DNA is so Dominant that he should be nearly full viltrumite. So maybe his human DNA lets his powers develop way faster than a 100% pure Viltrumite would. At some point of the comics they say that Humans could be the ideal match for viltrumites.
I think you are skipping maaaaany steps there… I would not even be wondered if they would end the season with the appearance of the other dimension Invincibles.
That was one of the best Scenes in the whole show! Literally the only time you see what he is really capable of. Imagine him just flying once over the guardians headquarter like this… thing cleared. Still leads me to the thought, that he faked his unconsciusness in hospital. None of the guardians could have harmed him at all, if he gone serious.
I always found it funny in the comics when thadeus rips of his fake beard and thats the irrefutable proof he is a viltrumite 🤣
