Pumpkin Bomb vs MCU, Watchmen, & Dark Knight.

Alright it basically a durability test. Who could tank the Pumpkin Bomb that reduced people to bones? And Would DP, Angel Dust, & Ajax withstand it and on that note The Watchmen or The Dark Knight characters, barring Dr Manhattan or Colossus.

pumpkin bomb?

The Pumkin Bomb that turn those business men into bones in Spider-Man during the Oscorp Celebration.

I doubt any of the people you listed could take it. Most of them aren't super durable.

For those unfamiliar with Pumpkin Bomb:

Why would you think anyone in Nolanverse is even worth considering?

It's possible that DP regeneration kicks in fast enough to save him, but I doubt it. Ajax gets fried. I think Angel Dust can take it, maybe KO? The rest Batman and Watchmen alike dies.

Colossus? Would the blast effect his organs?

Don't know body armor.
