Abaddon is the Eldritch God of Death. I physically can't draw him, because his form is incomprehensible. Sorry if pronouns are a bit confusing. Abaddon himself uses He/Him pronouns but Cosmo uses It/Its, because it's not a living thing anymore; its dead.

Abaddons abilities include but are not limited to: Rotting Touch (Causes Decomposition upon touching someone) Portals Third Eye Future Vision Fortune (lie detector, basically) Phase (noclipping) Flight Nightmare (can induce ultra-realistic hallucinations of whatever the target is most afraid of) Possession (Can leave Cosmos body and possess another)

If Abaddon uses Possession for an extended period of time, Cosmo will start to decompose more than it already has. Despite being rotted down to the bone, because of the immense Omega Energy from Abaddon, Cosmo has amazing agility and fighting prowess. Cosmos Soul is still inside his brain, despite being dead, so they share a brain. Abaddon and Cosmo have become good friends, and Abaddon likes to respect Cosmos boundaries on which he sets for his body. He willingly lets Abaddon fight evil with Gold and the Cool Skwad

abaddon also has a brother named Apollyon who later possesses (SPOILERS) Dusk's dead body after Steam kills him, making the fusion of Apollyon and Dusk THE most powerful character in the verse.
