@laylah: True, that is why Dormammu intrigues me a lot. Faltines are supposed to be among the most powerful races, and they are living constructs of magic to boot!! Living Tribunal has called on their power (Flames of the Faltine) to wipe out a universe/dimension once, so Dormammu, though powerful even now, is missing out a lot of his native powers. Umar, too probably, though she may have less potential than him. All the Faltines together should be a match for the likes of Zom, Shuma and above Galactus.
@full123: Agreed, but given Darkseid is a product of the Godwave, isn't he also supposed to be universal? Him collapsing the multiverse with presumably the power of all the New Gods and the Source does not count, because that's not just his own power. Just referenced that to differentiate personal power from gathered power. If he can access the full power of the dimension (Anti-Life entity?, not sure) from where he draws his omega powers, then that's probably different.
If Dormammu had the power of his entire Faltine race, he would win, no problems. But in his current form, where he is more bound to the multiverse, he is unfortunately, less powerful than Galactus probably. So, he loses here, in all rounds.
