Actually from reading this
Anos Vs The Daughters of Oryx thread this version of Anos doesn't even compare to the current one. Hell this version of Anos didn't even have resistances towards Conceptual Manipulation Type 2 much less Type 1. You know this match is old when Anos wasn't 2-A with Ven yet.
Deathsinging: which was the main win-con for Daughters seems to only negate Regeneration on the level of Low-Godly which is completely useless to Anos who has layered High-Godly.
So not only can Anos resist Death-Singings regeneration negation he can also resist their level of Conceptual Manipulation as well. So actually a future re-match needs to be made to see who actually wins since Anos has undergone massive upgrades to his profile since June 2021.
