Future! Castiel

Background

Castiel rescued Dean from Hell and watched over him per Heaven's orders. He broke his ties with Heaven after Dean exposed them as wanting The Apocalypse to happen. Despite his newfound loyalty towards Dean, Sam Winchester ended up saying "Yes" to Lucifer and victory fell towards the Archangel rapidly. The Croatoan Virus was unleashed and millions of humans died. Instead of fighting against Lucifer and his demonic army, Heaven abandoned Earth. Without his connection to Heaven.

Abilities

Supernatural Awareness - Although Castiel had been stripped of most of his powers, he was still able to detect that Past Dean had time traveled to the future. Marksmanship - Castiel was good enough at using firearms to survive the Apocalypse for five years without his angelic abilities.

Weakness

Mortality - Being a human, Castiel was vulnerable to diseases and any form of physical harm. He presumably had a limited life span at this point.

Personality

This Castiel had become bitter and depressed with the state of the world and humanity's losing battle against the demons. Most of all, he was unhappy and unable to do anything about his Dean's change in behavior. His former ward had also become bitter but also ruthless, willing to torture others, kill the slightly infected, and sacrifice his own men, even Castiel himself. Being the only angel left to fight alongside humanity also took a toll, though Castiel brushed it off by focusing on women and drugs during his free time. He enjoyed arranging orgies and caring little on his hygiene. Stripped from most of his powers, Castiel had to rely on human weaponry such as guns. Much like his own counterpart, Castiel retained a strong loyalty towards Dean. He chose to go on a suicide mission on Dean's command. Although he had accepted his fate, he openly preferred Past Dean, showing a longing for a world prior to his own.

Physical Appearance

This version of Castiel retained Jimmy Novak as his vessel. Unlike his counterpart, he had facial hair and a generally messy appearance. Outside of missions, he wore loose-fitting gray shirts and jeans. During missions, he armed himself with weapons and wore a brown jacket.
