Killer

"Massacre Soldier" 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. He and Zoro are the only supernovas who are not Captains. Coincidentally, they are also the only ones who hold no apparent Devil Fruit Abilities.

Appearance
Killer is both a lean and lanky masked man, wearing a full-head futuristic-looking helmet with long wild blonde hair that falls down to his thighs. He wears a yellow polka-dotted black shirt with an open collar that shows his chest, and pants that resemble those worn by real world Native Americans. (This style is often seen in fans of Heavy Metal.) Killer also had a red scarf around his waist. He carries a pair of hand guards which have very long detachable scythes connected to them. When not fighting, these scythes are placed in a large sheath tied to his right hip.

Personality
Like the rest of Kid's crew, Killer comes across as both level-headed and mildly arrogant; where in the former case, probably more so than their Captain ever will. Of course, this does not mean he is not as enticed towards violence as anybody else on the crew. He also remains fairly silent during combat, save for this slicing of his blades, and tends to focus on the elimination of his enemies.

Abilities and Powers
Killer is seen using a pair of scythe-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 the enemy's flank, or other exposed areas. Combined with the agility he has so far displayed in combat, and the notion that 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 is later seen rejoined with 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, in the face of a daunting Marine attack. During the battle, Luffy remarks how he will be the one to find the great treasure One Piece, Kid responds to this statement by ceasing current fighting, and facing Luffy. After a brief recollection between Captains, on how their journey was met with laughter and dismissal at their crews dreams, on their route along the Grand Line, the crew escaped together.

Current Events
The crew managed to defeat the Marines and headed back to their ship to escape the island. Destroying a bridge to halt enemy progress, their crew was amazed at the tenacity shown by the Marines, as they continued the chase despite the bridge being destroyed. Their attention is drawn at that moment, however, to the presence a Pacifista, whom they first assume to be the Shichibukai Bartholomew Kuma.

Trivia

 * He is noted to bare some likeness to the Soulcalibur character Voldo. Both characters have a similar body build, use a strange but agile fighting style and have dual hand-held weapons capable of spinning around. Killer wears a mask, Voldo himself is often seen wearing a mask in the Soul Calibur series. However, it is unconfirmed if Killer is based on or inspired partly by the character.
 * Killer's helmet has been noted to bare resemblance to the French musician Guy-Manuel de Homem-Christo's helmet from Daft Punk. Daft Punk were made famous in Japan by their animated film Interstella 5555: The 5tory of the 5ecret 5tar 5ystem, during this time the duo were wearing outfits made up to make them look like robots.
