Cascavel Morea (カスカベルモレア, Kasukaberu Morea) also known as Zero (零, Rei) is a Pirate, former mercenary, and the Second Mate of the Black Heart Pirates. Before joining the Black Heart Pirates, Morea was a well-known mercenary who participated in various armed conflicts around the world and was hired by several anti-government groups to be a solider in their war. During his mercenary career he was recruited by the Revolutionary Army and worked for them for a while, but left the group due to unspecified reasons. Morea is wanted criminal with an incredibly high bounty on his head and is sought out by the world government due to his ties with the revolution army and his assassination attempt on Saint Roswald, one of the World Noble, an act which is punishable by death.
Having been on the run from the world government due to his actions, Morea was later approached by Blackbourne Raven, captain of the Black Heart Pirates, and was asked to join the crew, Morea accepted the offer and joined the Black Heart Pirates as their assassin. He was later appointed as Second Mate of the Black Heart Pirates, making him the third in command after Captain Raven and First Mate Hanzo. Although not an active mercenary anymore, Morea is still a well-known veteran who possesses intel on every active mercenary in the world, and it is said that those who are not aware of who he is, are not worthy of being recognized as part of the elite.
Morea's appearance is taken after the shady, creepy archetype. He is depicted with bright green hair and his eyes closed, belying a mysterious nature. Despite his age, Morea appearance is that of an early to mid-twenty-year-old person, he is unusually thin and tall with very sharp features giving him a skeletal appearance. He also keeps his face set in a wide mocking smile, which he only wipes off on rare occasions of annoyance, surprise, confusion, or even sadness. Whenever he opens his eyes, they are shown to be golden-yellow irises with snake-like slits for pupils. He wears a simple black suit with a white shirt underneath, short brown gloves, and brown steel-toed shoes. He dons a pair of black trousers held up by two brown belts. He completes the outfit with a black fedora hat to close the shady visage.
