After the timeskip, Killer is shown as more muscular and with a thicker neck. He has grown a goatee and is shown to have a scar on his left arm. His hair is shorter, now only reaching down to his back. He has changed his attire after the two year timeskip to a blue t-shirt with his customized Jolly Roger on. Like the rest of Kid's crew, Killer comes across as both mildly arrogant and level-headed; in the latter case, probably more so than their captain. Of course, this does not mean he is not as enticed toward violence as anybody else on the crew. He also remains fairly silent during combat, save for the slicing of his blades, and tends to focus on the elimination of his enemies. Killer is more knowledgeable than his captain in terms of historical facts, as shown when he informed Kid the meaning of the Ox Bell.
After the timeskip, Killer has been shown to be much calmer than his captain, advising him to be polite when meeting with his fellow Supernovas, and was then able to prevent a fight between him and Scratchmen Apoo from escalating while reminding them of the purpose of their meeting. He also seems to be more reasonable than his captain, which is in contrast to his name, as he tried to reason things out rather than immediately trying to start a fight.
Killer is a fearsome pirate and combatant. His skills have earned him a bounty of Beli200,000,000 which is considered to be very impressive for a rookie, even within the Grand Line. Like his captain, he was able to resist Silvers Rayleigh's burst of Haki. Killer's style of fighting seems to rely mainly on agility and speed, which he uses to overpower his opponent before they can strike him, or to dodge attacks. He was capable of fighting head on with the fellow Supernova Urouge, though the latter had not increased his muscle mass.
Killer is seen using a pair of scythe-bladed weapons attached to his armbands 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. This, combined with the agility he has so far displayed in combat and the notion that he is not afraid to kill, makes him a formidable foe.
