Dario has brown fur and usually is seen wearing all black.
Dario is a master manipulator, and has been known to be extremely ruthless. His enjoyment of violence has added to his reputation of being extremely sadistic.
As a kid he never saw his father, and lived with is brother and abusive mother. The two brothers cared about one thing: having fun. After twelve years of being abused the two continued to keep a positive outlook on life. Though one day while playing soccer with their friends, the brothers were called into the house. After talking back to his mother Dario was about to get beaten (not that uncommon as you expect but this time) with a empty bottle of tequila), until his brother bludgeoned their abusive mother to death with a bull statue. This statue would be very important to him later in life. While witnessing his mother’s brutal murder, he found complete enjoyment of it discovering his love for violence. Ten years later he would successfully become a successful “businessman” giving multiple people unique opportunities (often working against them). That year he would open a underground fight club called “The Temple”
Dario is a master of the art of the deal, he has managed to negotiate with successful businessmen and leaders of major criminal organizations. He also has been shown to be extremely deceptive even managing to trick a entire jury when he was put on trial once. Dario also is able to get into his enemies heads quite easily, via a device that allows him to read others minds, so while he can’t win a fight physically, if he can mentally torment his opposition he’s already won.
Due to Dario preferably using brains over brawn he is a easy person to lay a blow on. It is also known that even if he makes a very convincing lie, there always will be someone who sees through the lie. His usual only form of offense is using his brother as his bodyguard and doing the fighting for him.
Dario might have a handgun as his only weapon, but when it’s for hand to hand he has his (possibly a cannibal) brother at his command.
He almost was going to be a monkey, as a reference to the short story the monkeys paw.
