gladiator's definitely the stronger character in all regards, but blackbeard's cancelation thing could be problematic.
at a base level gladiator's pretty damn beasty - talking better than base hulk's level for strength. pre-green scar anyway. gravity tricks have worked on gladiator and his race in the past (Nova Corps uses gravity manipulation for an overwhelming amount of their actions) but i'm not sure blackbeard can deliver the necessary output for it. doubting it, but one piece can weird enough to need confirmation on the best he's done.
<<; but that 'touch me and get cancelled out' needs more explanation.
