Pick the power, get the curse (or, "welcome back Demigawd")
Sorry to interrupt the, um, "fun" between Whirly and GS with some actual comic discussion, but now that I'm back from my concert tour, I wanted to add a couple of topics that I thought of.
Would you rather have:
1. Power Cosmic - but you have to consume a planet with at least a million people every year.
2. The power of a million exploding suns - but you have an alter ego who could kill everybody you know and love if you lose concentration for even a second. You also get constantly bombarded with data about everybody who is going to die if you don't help them RIGHT NOW.
3. Asgardian Odinpower - but you have to sleep for 1000 years every 10,000 years. You'll be responsible for governing and protecting the lives of an entire dimension. Oh, and one day, a demon is going to come and kill you and your planet violently, and you'll be haunted by the gory details every night.
4. Vampiric powers - Enhanced strength (CL10), immortality, flight, super speed, telepathy - you're powerless during the day, and have to kill one person per month via neck-biting.
5. Planetary level psionic power - but you'll be plagued for life by the thoughts of everybody within a 10 mile radius - even while sleeping
6. Unlimited oan power - but if you're touched by anything yellow (except sunlight), you become deathly ill for 24 hours. If you're touched again by yellow within those 24 hours, you die.
7. The powers of Captain Britain - but you have to fake your death and never reveal who you are to anybody, otherwise everybody you know will be killed
8. The powers of Rogue
9. The powers of Flash - including speed force, time travel, infinite mass punches, the whole shebang - but everybody will permanently move in EXTREME slow motion to you. What appears to take a second for one person will actually take 25 minutes from your perspective.
10. Just be your own smiling self.
Note that I've taken some liberties with the severity of some of the curses. It's just for balancing effect.
