What's wrong with Invincible characters durability?
Why does people think Invincible characters durability is weaker than main characters durability from DC and Marvel? Is it because equals or superiors hurt them? We've seen kryptonians get holes blasted through their hands and arms, jaw knocked out of socket with one hit, bones blasted through them like butter. We've seen asgardians get their hand chopped off, eyes stabbed out and all of this was either done by peers are by a sharp object.
What makes Invincible characters any different? Nukes, planet explosions, the sun, none of that hurt them, the only thing that bypass their durability is either their equal or someone who is superior.
