This isn't just for Hulk, it could be for any situation where you're fighting an enormously powerful villain and there are a lot of innocent civilians around.
How do you represent the threat to civilians and how do heroes save civilians? I understand that the Doom Pool represents this in the abstract, but the PCs don't really have a good "roll to reduce the Doom Pool" option. And I want the Hulk to spend his actions attacking heroes, not just rolling to increase the Doom Pool.
Should there be a watcher "character" just representing the overall chaos that takes actions? Or multiple "characters" brought in by spending doom dice? ("ok, I'm spending a d6 from the doom pool to interrupt the action order with a new character called 'falling debris' it's going to fall on a little old lady who is walking her dachshund unless someone wants to react?")
Also, I know the book explicitly talks about a villainous version of Wolverine using Berserk and the dice going into the Doom Pool, but is that really kosher? It seems a little harsh on the players who feel the increased effectiveness of the attack against them and are the ones to suffer the cost of activating the ability.
