^^ AE has nothing to do with Chaos King. AE is not,
and never been the "nothingness before everything."
Chaos King has nothing to do with the Infinity Being or Nemesis.
Nemesis is the Infinity Being, but unfortunately what we saw
was a watered down version of the original monster.
Why?
Because by the time Nemesis's consciousness (Ego gem)
was united with it's power (Infinity Gauntlet)
The Infinity Gems had gained their own separate consciousness,
so when Nemesis was whole, they were all struggling for control,
making it "vulnerable,"
this, of course was a plot-device,
since there was no way anyone was defeating Nemesis.
Still,
it was able to obliterate the two Prime UniverseS of Two separate MultiverseS,
(one of which was 616)
simultaneously with a thought.
Also, a fraction of the Gems' energy was enough to create UniverseS back to back stacking them,
leading to possible Omniversal destruction.
This is monumental but the big bad apple is:
I believe a fraction of Nemesis' power remade the Omniverse on panel.
Which in-turn would mean, a fraction of the IG's power.
