Lunatic has a history of not giving protags and strong characters and town. E.g. in Stormlight Archives he gave arguably the two main characters, Kaladin and Jasnah, as fakeclaims. In MMA mafia he gave boxing and JJ for mafia, for Ozark he gave the entire flipping Byrde family.
Lots of flaws here:
1) You have to assume that he gave Mark Grayson as a fake claim. In the OP, Lunatic clearly says he gave a hint towards a role claim, not a character claim.
2) If he did give a character claim, what was the purpose of making it an open set up with all the characters.
3) Shallan Davar in Stormlight was a main character and was town. In that game he also gave 3 fake claims and it wasn’t an open setup.
4) In Ozark mafia, scum were literally the main characters. Town had quite a few main characters as well like Jacob Snell, Helen Parker, etc
5) In MMA mafia, he didn’t give any fake claims at all. And again it wasn’t an open set up. I was Muay Thai that game. There was Karate and Judo, both popular forms. Not to mention wrestling.
I don't believe that Lunatic would give the main character of Invincible to a town player because it would essentially clear them since people blindly believe thematic analysis.
Let’s say for instance that this is true. You would have to assume that I as scum would claim Mark Grayson, the main protagonist of the game. That’s just insane especially when it’s clear scum were not given a fake claim (which we know is something he has done before in MMA mafia)
