Plant Physiology/Transcendent

So, currently, I’m thinking about making my oc similar to the flower tao possessors from hell’s paradise. But of course he’s more op, you can’t kill him just by cutting his lower abdomen cause he possesses absolute immortality via Absolute regeneration (Not even gonna mention his absolute physical condition 💀). And i was thinking about giving him bio-solar dynamo, which’ll be limited by basically his own imagination and ingenuity.

You are going to battle 100 2-A: Multiverse level+ strength-based rampaging Transcendent Werepires & 100 2-C: Low Multiverse level Knowledge-based Transcendent Undead Plant Monsters,What non-Physiology strength-based power and knowledge/mind based power will you use to combat this threat?And once you win the combined physiologies of one group will be added to your Physiology, which one?
