I am now something that I shouldn't be... A rogue God.
~ Firebrand

Cosmic Entities are extremely powerful beings that can be classed as aliens of exceptional strength, godlike beings or superhuman characters who surpass the usual levels of power found in superhero fiction: in mythology they would normally be considered "gods" but not all Cosmic Entities need to be Deities and vice versa. They are always trying to take over or rule the cosmos or overturn another Entities or Deities.

(Important Note: Do not add beings that are or have been actively worshipped by a large following, as they would be classed under "Deities" instead).
