If you look at it, these were very similar themes floating between these two properties. These similarities may only be surface level but they are also inescapable. They even try to broker a treaty between good & evil. Honestly, I think the comparisons are so strong because the Charmed Ones only exist in the magical world. They’re completely absorbed by and have no personal/human lives outside of it.

A group of powerless demon fighters portal all of the world from their command center to fight demons in a shadow war hidden from mundanes. Only armed with their spells & potions (or runes), this group tries to keep balance but there is one main character with power above the other due to the demonic blood they were given in their infantry.
