Ainz Ooal Gown Vs Anos Voldigoad

Ok, so I just finished watching The Misfit of Demon King Academy and boy was that just a ridiculous op character. So who would win in a fight Demon King Anos Voldigoad or Sorcerer King Ainz Ooal Gown?

Now both would be at their strongest/prime so the demon king for example would have regained all his strength, powers, etc, and not be at his 1/10 as he was slowly getting it back over the anime. (I got to admit I don't even know if he gained it all back in the anime or not only that he said when being reincarnated that enough time has passed that he was over the 1/10th power.)

Also, they cannot fully retreat from the fight so Ainz can't use GATE to go to Nazarick or Anos use GATOM to get out of the fight but they can be used to avoid attacks or get some distance from each other.

These fights are to the death.

While they can make space while fighting or go into hiding like hiding in trees, caves, buildings they will be drawn towards each other but not know exactly where the other is.

Scenario 1 - They randomly come across each other with Ainz and Anos only bringing what they averagely wear when traveling. (So when they meet before getting into a fight Ainz would look like Momon)

Scenario 2 - They are both aware of each other and have a day to prepare for the fight.

Scenario 2B - Nps/sidekicks are allowed.

Scenario 3 - Like Scenario 1 but during the middle of the fight Reinhard Van Astrea joins the fight because fuck it. 1v1v1
