@rothschild_banker: How powerful is FAA anyway? Is she Multiversal, Outerversal, Omniversal, etc? Also, since this is composite Thanos, the IG and Cosmic Cube could possibly give him some extra power.
Just know she is powerful enough to Solo Marvel casually.
She had reached the absolute top of the cosmology and met with god. This is why she solos, Because she managed to survive the Creator, the Being that all meet at the end of there journey, and get erased. When you meet the creator you lose your sense of self and your idea of being. GOD in her verse=OG TOAA, the fact she survived seeing her creator, with a memory Device it saved her from getting completely obliterated.
This is a feat no one in Marvel can do.
Spiderman met TOAA once IIRC.
