Trevor

Chapston D. Trevor is a Marine Commodore and former painter. He is the older brother of Chapston D. William. He initially appeared as an antagonist determined to find and kill Jason Locksworth, the man who killed his parents. Despite his complicated relationship with William and the Devil's Luck Pirates, he has gradually developed into a reluctant ally in their fight against the influence of the Aeons.

Trevor has been stated to be of a power level equivalent to a weak Vice Admiral or a strong Rear Admiral, but lacks the rank as he often lets those who don't know anything about Jason Locksworth go.

Appearance
Trevor is a six-foot-tall marine with a strong overall build. He wears a fine black suit complete with a red collared vest and a white jabot. He also wears a white Marine Justice Coat with red epaulettes over his shoulders. A brown ponytail pokes out from behind his bicorne hat, which is adorned with a long red feather.

Personality
Trevor is a very passionate man who struggles with controlling his temperament. His goal in life is to kill Boss, and he will stop at nothing to achieve that goal. In this vein, Trevor also believes in Absolute Justice. However, he opposed Arzen's human experiments along with Marrow's tolerance of human trafficking for selfish means and still holds out hope for William.

After many revelations, Trevor has agreed to stop chasing the Crew, but won't stop chasing Boss after defeating Jefferson. However as of Episode 40 he appears to have gone back on not chasing the Crew, although the Crew hasn't appeared to notice or care. He hates fish, specifically carp.

Overview
As a Marine Commodore, Trevor has all the authority and influence that accompanies the position. He is also a skilled and strong leader, capable of making quick decisions on the fly. In terms of individual combat, Florence estimated Trevor to be about as strong as a weaker Vice Admiral, and that he would actually have the rank if he focused less on killing Jason Locksworth and more on his assigned missions. Trevor has also killed a Sea King when he was at full power.

Strength
Trevor has an insane amount of physical strength due to his decades of intense training, so much so that he's even surpasses Ragnar's level of brute force.

Master Swordsman
Trevor used to carry the "Sword of Justice", an Ō Wazamono-grade (second-highest) Meito. With this sword he was able to cut cannonballs out of the sky and effortlessly sliced a robotic pillar in half. He also cut down Verona and Ragnar in one attack. This sword was eventually stolen by William, who used it as his primary weapon throughout the crew's subsequent adventures from the Oasis up until Jefferson's defeat on Stäringard. Trevor then briefly reacquired the sword in Episode 34 during the battle against the Sea King, but lost it to William again soon after. For a time he wielded an ordinary cutlass before getting a rune covered longsword on Stäringard.

Six Powers
Trevor can use Geppo with ease.

Haki
As stated before, Trevor is considered to be about Vice Admiral level in strength and it was confirmed in Episode 18 that Trevor has access to Armament Haki. Trevor appears to be naturally inclined towards learning Armament Haki.

Art
Before he joined the Marines, Trevor was an accomplished painter. Since Trevor joined the Marines very soon after Boss took William and killed his parents, he accomplished all of this within a very short period of time when he was about seven.

William
Trevor and William are brothers. Trevor thought William was dead for several years, and had been searching fruitlessly all the while until they came across one another at sea one day. He is frustrated that William chose to be a pirate instead of a Marine. But after the events at G4, their relationship is much more strained although Trevor appears to still hold out some hope for William. After fighting with him during the Aeon Saga, Trevor agreed to stop chasing William and the Crew, but won't stop chasing Boss.

Jason Locksworth
Trevor loathes Jason Locksworth, ever since the man killed his parents and stole his baby brother. He's been searching for Jason for over a decade now, desiring nothing less than absolute revenge, absolute justice.

Arzen
Trevor hates Arzen's experiments on living beings for the sake of "Justice" as Trevor believes Arzen does this mostly to satisfy his own ideals of science. His feelings eventually boil over when Arzen demotes him, causing him to turn against the Vice-Admiral.

Jefferson
Rear Admiral Jefferson used to be Trevor's superior officer. However, after Trevor declined his invitation to join the Aeons he framed the young Commodore for working together with pirates and tried to kill him. This caused Trevor to resent Jefferson deeply.

Marine Subordinates
Trevor appears to treat his underlings very poorly, from killing the lesser Marines who disappoint him to outright terrifying some of the higher-ups like Commander Bait or Captain Marrow. He also left the unconscious Florence on the Devil's Luck Pirates' ship when he boarded them.

Marine Superiors
Trevor seems to be decently respected by the higher ups in the Marines, as he's very dedicated to ideals of Absolute Justice. Trevor believed that he would be able to help William become a Warlord as the Timberlord's replacement, although it's unknown how successful he would be.

History
Trevor's noble parents were killed by Jason Locksworth about twenty-eight years ago, who also kidnapped William in the process. Trevor swore revenge and started painting and writing poems. However, he soon joined the Marines for one purpose: to become strong enough to kill the man that took everything from him. Trevor was raised by Arzen and the Marines when he was young and has been training ever since. Currently Trevor is held in the Aeons base after he lost to one of the members.
