It depends in all honesty, if you're speaking of the planet busting, Hyperion overpowering, heat vision capable of searing through Hulk.
The one that can fly through a star, the one that has supremely fast reactions, can throw a crap ton of punches very fast type of Gladiator among many other feats.
He just may be in with a chance. But the ruined shell of a character Marvel writers have made has no chance. He probably gets beaten badly due to Blue Marvel emitting some form of radiation that weakens Gladiator or something.
So if Gladiator didn't have this crappy jobbing aura. He may have a chance at getting a few wins. But otherwise Blue Marvel takes this.

I think you're right, but I do think he was 'villainish'. I think that's all you need to be a villain be in circumstances that make you fight other superheroes, a bit like Namor.
