No, King Crimson literally erases time. It's why he's immune to actions that occur while his ability is active. It's even described on his stat page that if you recorded what happened while his ability is active on a camera, the camera would jump ahead, skipping what happened. The consequences of those actions still remain, but the actions themselves are erased. That's what makes King Crimson so terrifying. It's far more than just erasing memories.

And as we know, most close-range types without time related abilities can't really keep up with King Crimson. Silver Chariot is a top-tier close range type and still got it's ass kicked by King Crimson (twice). It would take a close range type with powerful abilities (something like The World or D4C Love Train) or an especially powerful long distance type (like Tusk ACT 4) to stand up to him.

That said, most of King Crimson's effectiveness does lie in its ability. If an enemy can bypass that then all they're left with is a slightly above average punch ghost. Tusk ACT 4 in particular would be very well suited to fighting Diavolo.
