I watched season 2 today and damn dawg if I was Mark I would’ve quit by episode 1 (of season 2, I forget most of season1). Holy shit does Mark get fucked up in every fight. Me personally I’m not built for that kind of lifestyle, especially when my only back up is shitty ass teen team or whatever they are now. That’s just me though
Until I either get killed or defeat Viltrum.
Or maybe I’ll be semi-retired if I survive long enough, like Blast from “One Punch Man”.
Mark obviously knows that he’s one of Earth’s greatest assets as a protector and has the potential to be the strongest person on Earth. He’s LITERALLY the son of Omni-Man and he knows what the stakes are, so it’s not like he has a choice to quit. Or else Viltrum is gonna come to Earth and Earth will most likely lose without Invincible.
When he thought of quitting in Season 1 Episode 7, it was because he believed that there were other superheroes who could help out the world.
But after Season 1 Episode 8? That changed.
So yeah, he’s in it for the long run. Whether he likes it or not.
He’s literally prepping to fight for freedom against the Viltrumites.
