This is another explanation part. I see a lot of people are confused on some stuff so ill explain some things
1. He has all the powers of Overlord, Rencarnated as a Slime, and Misfit at Demon King Academy. However he is rather limited in his current body, having to sacrifice a part of his body to activate the more powerful skills amd spells because all that power is too much for his Overlord body to withstand.
2. He does and Doesn't have a soul. His true body holds too much energy to exist and interact with normal souls so he created an artificial soul to place in his body. And yes, he is in full effect of his contract unless he breaks it himself, which he won't.
3. He can immediately recover from any damage besides holy damage. For story purposes its because he will draw a lot of attention if he is immune to the one damage type sinners are killed by. Real reason is because its boring if he has absolutely no risks
4. If you have any Hazbin Hotel or Helluvaboss OCs you would like to add. Just comment the basic information and ill see if I can add them.
5. God, Roo, and Max's true power is unique. And so is their goals
God= Creation. His main purpose/ability is creation. Though he isn't very good at control or true endings since he made the free will part of the soul.
Max/Entity= Endings. He has complete domain over the end of everything. Every soul in hell thats dies in hell belongs to him unless it is completely destroyed. Also, everything that was lost is his. That's how he has so many items but is terrible at creating things.
Roo= Corruption/Evil. Main ability is to twist souls to do devious things. His main thing is causing chaos for entertainment. He is closer to Entity than god but doesn't mean anything to offend God or Entity. He just wants to see new and exciting things.
