Is there a chance Invincible will be re-proposed as a PG?
Yes, I know it's been proposed and rejected, but many characters on this wiki were also rejected first and then approved. The main argument used in the proposal is that Mark was too lethal for PG, having brutally murdered Onaan, but I feel the context wasn't properly analyzed. Both Thraag and his sons were ACTIVELY trying to kill Mark and his family, with Thraag brutally murdering Oliver in front of Terra. Onaan himself had sadistically taunted Mark that he would kill Terra. And even so, Mark didn't kill Onaan outright, offering Thraag the chance to leave in exchange for leaving him and his family alone. Instead of accepting, Thraag mocked Mark, saying that because he was a hero, he wouldn't kill, and therefore he and his allies would die. Only then, when Thraag made it clear he wouldn't stop, did Mark kill Onaan.
As later revealed, Onaan was essentially a petty psychopath who led his victims to a pit to torture them to death. The only one who mourns his death is his sister Ursaal, and even she admitted that her brother was a monster.
Overall, I'd say that while the way Mark killed Onaan was brutal (crushing his neck), I'd say it was justified in the context of self-defense.
To emphasize my point, I want to compare this moment with the moment when Obi-Wan allows Captain Rex to kill the Guardian Agruss. Just as Thraag did with Mark, Agruss taunted Obi-Wan about not being able to kill him because of the Jedi Code, which prohibits a Jedi from killing a defenseless opponent. Obi-Wan responds by letting Captain Rex kill Agruss.
In other words, in both situations, we have the villain taunting the hero about not being able to kill because of their heroic ideals, only for the hero in question to respond by killing the villain.
Why, then, is Agruss considered justified in the case of Obi-Wan and Rex, while in the case of Mark and Onaan, it is considered "excessive"?
But anyway, that's just my opinion. So, with the points I raised, do you still think Mark is too lethal, or is it justified?
