By the end of the series, Mark would have likely beaten Battle Beast with roughly the same difficulty that Thragg went through to defeat him. It would definitely be a decent fight imo. Then again, Thragg should have become stronger by the time that he fights Mark at the end of the series, and Mark as we know wins that fight. I guess that it's anyone's guess as to how well he'd do.
Not enough to really judge Marks power level. He clearly knocked Allen down, but both were also wearing formal atire and seemed relatively injury free, so it wasn't likelyna battle to the death. Not compared to Battle Beast vs Thragg, or either of Marks fights with Conquest.
I can see Mark being stronger then Nolan by series end easily enough. Stronger then someone who could tear up Thragg who can casually rip him in half, that's another story.
Personally, I doubt Mark or Allen ever gets that strong.
