The “Persona Rule”, as I understand it, is that you can’t have two of the same persona on the same 3-character team. So, I can’t have OML, Patch, and Wolverine as a team, 'cause they’re all the same guy.
Now, Archangel was Angel (with feathered wings before Apocalypse replaced them with the metal razor ones). Ang3l is that guy who had the feathered wings, but was brought forward in time, and replaced his own wings with cosmic flame ones. He didn’t want to become like Archangel, and chose a different path. So, I can see why he’s “different”.
That explains why Ang3l and Archangel can be on the same team, in MPQ… right?
However, if someone brought yellow-suit Wolverine to the time of OML, and they fought side-by-side, they’re still the same guy, by the Persona Rule. Thus, we should be allowed to have the team of OML, Patch, and Wolverine. Not that I want to, just on principle.
Now, if MPQ looks at time travel like Marvel Comics usually do (I’d recommend that, as it’s based on Marvel), people can travel in time, but are on the same timeline, and the same persona can meet himself. It appears that MPQ is looking at time travel with divergent pathways, where every time you make a choice, a new REALITY is formed. In that sense, when Ang3l moves forward in time, he’s stepping out of the reality where he became Archangel, and stepped into one where several years have passed and Archangel already exists. This would allow two separate personas to fight side-by-side, because they are different people, from different REALITIES or dimensions. That wasn’t stated, like some other characters (i.e. Chavez).
I then posit that MPQ should do one of two things: By Marvel time-travel rules, make Ang3l and Archangel the same MPQ persona and not allow them to fight on the same team. OR Assume that all current different personas could time travel and fight side-by-side, thus allowing an OML/Patch team (thus throwing out the “Persona Rule.”)
Personally, I think the “Persona Rule” is fine as an MPQ game mechanic, but by Marvel time-travel rules, it’s incorrect. Either way, the Ang3l/Archangel exception poses a logical inconsistency within a game based on Marvel Comics/MCU.*
*No doubt Endgame will make new rules of its own with the relationship between parallel realities/dimensions and time travel.
