Re: Unmaking
This doesn't strike me as a no-win scenario. There are plenty of "no-win" scenarios in comics and RPGs, and heroes go ahead and win anyway, like they never got the memo.
To fix time problems, you need time solutions.
Coax Victor von Doom out. He'll sort this mother out in no time with his time machine, and my hero would owe a favor to one of the worst people in the world! There's some grist for your gaming mill.
I'm really surprised that all these thoughtful people are angry that this sort of thing might come up. Don't we, through our heroes, cheat metaphorical death all the time? Isn't that the meat and drink of superheroes?
As I read somewhere:
When Captain Cold freezes Batman in a solid block of ice, does the thought balloon read, "My chances should be better than this!"
And as I answer:
No, Batman busts out with the Bat Heat Ray and melts the block of ice, just in time to stop Captain Cold from crushing Comissioner Gordon and Robin beneath a giant frozen dinner or whatever.
And bigger calamities require bigger solutions, but superheroes always find them.

Now, if the GM won't let you get around a problem, then it's time to pull the plug on this particular subplot until you can figure out what you did to him to make him so sore at you.
