Depends on how many XMs. Vader could force crush a round half dozen at once, in his prime, I believe. While simultaneously sabering down a few more. Vader really is horrifying powerful. We've just gotten so used to seeing him that we forget that.
I also want to toss in a vote for Darth Jar Jar vs Hordak.
True, he doesn't even mention Force choking them, or simply basically snapping their necks with the Force in between tossing away waves of them... Not to mention even if (and it's a next level kind of IF) the physics of lightsabers "explode" enemies... then you have the lightsaber throw! You're a very safe distance away then.
But I can't quite find it in me to dignify the 2nd part with a legit reply... And I'm one to enjoy Darth Jar Jar in many lights. But sadly we have no data on his combat prowess outside of limited action in VS separatist droids. Dang it, you made me articulate some semblance of a reply...
