You really think Black Heart could survive 20 Kryptonians beating on him?
Back on topic :
Probably Classic Juggernaut with force field up. Butterball. Absorbing Man (absorbed Captain America's shield properties). Harold the Viking (the guy from that Thor miniseries). Probably more that I'm forgetting.

Yes Blackheart can survive 20 Kryptonians beating on him.Here are some of the shananigans he did when his betrayal was discovered by Mephisto.
As you can see, Blackheart just keeps being a troll to his oldman while he is being squished over and over again .Blackheart doesn't even say "ouch" or even shows that he is hurt or in pain. More impressive is that Blackheart was in his father's realm were Mephisto is more powerful.Not to mention he displays the ability to reform over and over
But can he survive a beating from 19 Kryptonians plus one Kryptonian with Mcguyver on his back? Or will the Swiss-Army-Man-With-Mullet make the difference?
So that means Electric Superman, Strange Visitor, Martian Manhunter, Shadowcat, Apparition(and all her other variations in the Legion Of Super-Heroes' 7 billion reboots), The Ray, Alan Scott(I remember his first appearance in the Golden Age he went intangible), I think anybody with a Mother Box(not positive), Metamorpho(since he can turn into a gas state), Flash Family members, Miss Martian, other white Martians, Malefic, Vision, I think Apocalypse, Marvel Dracula(since he can turn to mist)-----
using butterball in a survival gauntlet in terms of pure physical output is cheating and you know it. Completely immutable. Can't even get into shape, stuck fat forever, unless matter manips could give him a better form. If that was the case in his position I would be begging any matter manip or reality warp to at least age me to 23-24 and put me in reasonably good shape. Not even asking for stellar conditions, just reasonable.
