I'm writing an Invincible fic where I adapt the show story in my own way since season 3's episode 7

(Technically in the fanart tag because there is no fanfic tag)

I am writing an Invincible fic where I adapt the events of the story, with the Conquest battle's end as the starting point. (I know that the Conquest battle hasn't come out yet, but... I'm doing it since then anyways because kickstarting the fic with a battle will be unnecessarily harder to me).

Some things I want to change are how the alternative Marks are handled. I basically want to write Full Mask Mark and Polite Mark into the story and try to redeem them instead of them being just canibalized by Sinister Mark. I even came up with "hero" names to distinguish them from Invincible: Unstoppable (Full Mask Mark) and Marksman (Polite Mark).

I dunno whether or not to adapt the whole Anissa... thing. I'm asking for feedback on how to handle the whole thing better.

And I'm adding two OCs of my own. A human OC with eldritch powers (Because we don't have enough magic users) and another Viltrumite woman.

So... any feedback on how should I do it? Any arcs from the comics you wish to not read in my fic? Please, I'm interested to see opinions!
