Originally posted by TrocityBased on hype Marr is like Malgus level, which I obviously don't quite agree with. But being one of the most powerful of the Dark Council and being feared enough that no Sith has tried to dethrone his is testament to his strength. So based on that, as well as his hype, it's safe to bet he would put up a fight.
It absolutely wouldn't be a good fight, Marr has no chance at all.
