Gabriel, or better known as the 'left hand of God', was recruited by the Vatican to hunt down 'monsters', not knowing that he, himself, would one day become one of their targets as well...

He's very loyal, though he mostly keeps to himself; he likes to make sassy/witty remarks but he's always careful not to take things too far.

He's unusually strong for a 'simple' human and his senses are strangely heightened, making him the perfect weapon against the forces of evil.
