Killer

"Massacre Man" Killer is a masked pirate and subordinate of Eustass Kid. He is one of eleven pirates who have been referred to as "The Eleven Supernovas" on Sabaody Archipelago whose bounties are higher than 100,000,000 when the Straw Hats arrive in the place. He and Zoro are the only supernovas who are not captains.

Appearance
Killer is a masked man with long wild hair. He wears a polka dotted shirt and pants that resemble those worn by real world Native Americans. He carries around a pair of hand guards with have scythes attached to them. When not fighting, these scythes are placed in sheaths on each side of his hip.

Personality
Killer appears to be one of the more level-headed members of Kid's crew. Of course, this does not mean he is not as enticed towards violence as the rest of the crew

Abilities and Powers
Killer is seen using a pair of scyth-bladed weapons that are capable of spinning around or being used as hand scythes. These weapons can also be used to block other weapons, leaving the foe open for Killer to kick in the sides. Combined with the agility he has so far displayed in battle and the notion he is not afraid to kill, he is a formidable foe.

Sabaody Archipelago Arc
After a long voyage following one of the Log Pose routes of the Grand Line, Kid and his crew came to the Sabaody Archipelago to prepare themselves for the New World. Killer was seen fighting Urouge for reasons unknown upon first introduction, a fight that was broken up by X. Drake.

He later rejoined his captain at the Human Auctioning House to observe the auction taking place. After interruptions by Luffy, Killer found himself fighting to escape alongside Trafalgar Law and Luffy's crews. During the battle, Luffy remarks how he will be the one to find the great treasure One Piece, to which his captain Kid stops fighting for a moment. After a brief recollection on how their journey was met with laughter at their crews dreams on their route along the Grand Line, the crew escaped together.

Curent Events(Spoilers)
The crew managed to defeat the Marines and headed back to their ship to get away from the island. Destroying a bridge to halt Marine progress, their crew was amazed how the Marines were still trying to follow despite the bridge being destroyed. Their attention is drawn at that moment, however, to the presence of the Shichibukai Bartholomew Kuma.
