This is the Scarlet Witch from the Darkhold: Omega comic who is now the Goddess of Chaos via absorbing and taking full power and control of Chthon and the Darkhold.
With a fraction of Chthon's powers, Wanda was able to cause the House of M event which wiped out 98% of all mutants across Marvel's vast multiverse simply by saying "No More Mutants". This can be theoretically debated to be a high multiversal-low omniversal feat of influence/power for reference.
Now that she has absorbed ALL of Chthon and has mastered the Darkhold, who along the line can she beat, not beat, and tie up with (if my order is actually pretty accurate then basically where does she stop when it comes to strength level).
3. God of Magic Dr. Strange
4. The Black Winter
5. Rune King Thor
6. The Phoenix
7. Black Priest Strange
8. Witching Hour Wonder Woman
9. White Phoenix of the Crown
10. The Presence
12. God Emperor Doom
14. The Unkindness Raven
15. PR Beyonder>=True Form Oblivion
16. The One Above All/God of ALL Things
I'm not entirely sure if the list is accurately in order, but I think I did ok with my limited knowledge. If not then just go through and tell me who you think she beats and who she doesn't. I believe she either barely beats or stalemates The Unkindness Raven who I believe is just barely below the true concept of Oblivion itself...who Marvel's Beyonder at full power is above most likely. So there.
