NEO Vs Galactus
-Galactus is at 100% and NEO is at 100%
-No holding back
-Both serious and bloodlusted
-Win by death
Galactus isn't on full par with the abstracts although he is close. But I can't say I'm a Neo expert. My guess would be Galactus though because he is universal level on his own, but his weapon the ultimate nullifier can erase a universe by itself. That combined with his own power might give him the edge.
I thought the UN was multiversal able to wipe out an infinite multiverse? UN would be a real stomp.
Well, if standard G is just universal as you claim, NEO would likely take this. He defeated two universals, each of whom are strong enough to murder Yggdrasil, the god computer of the Digimon universe, he himself is an artifical digital lifeform exceeding Yggdrasil, can turn all attacks to 0s and 1s passively, exceeds time-space (i.e. somewhat similar to existing outside time-space/reality, this ability works in Digimon by making you immune to all attacks unless those attacks can exceed time-space/attack outside of time-space), can create/destroy universes, etc. He was also just at a fraction of his power during the whole encounter IIRC.
