Tyrian Callows

Looks: 5'11 but stands like he's six feet tall; thin, but athletic and toned; long black hair braided to look like a scorpion stinger; actual scorpion stinger for a tail because he's a Faunus; white vest and loose white pants with leather belts across the open chest; scars visible on his chest; brown cloak he uses to hide his stinger when needed; wrist gauntlets with blades; gold eyes that turn purple when using his Semblance or his poison.

Abilities: Wrist gauntlets with mounted claw-like blades, called the Queen's Servants; corrosive, purple poison in stinger that can kill as well as melt through metal; Semblance allows him to disrupt other people's auras; purple aura to shield himself; high speed and acrobatics like a circus performer; able to hear metal 'shing' as a weapon moves so he can know where to block; fast enough even to use his tail to block bullets without looking; highly skilled tracker and can find people across Remnant; very clever and always one step ahead of his rivals.

Personality: Highly unstable. Prone to manic bursts of laughter; enjoys jumping around and posing theatrically, as well as sitting crouched on surfaces or high places like a gremlin. Very sadistic and enjoys causing pain and fear. Somewhat masochistic and only gets more hyped for a fight when hurt, unless it's extreme enough to make him angry, like cutting his tail off. Worships Salem with reverence; considers her a goddess because she can control the Grimm and wants to help her lay waste to Remnant and all its inhabitants, including himself at the end.

Doesn't consider anyone in specific his rival, because everyone is equally fun to fight, but took advantage of Qrow thinking they were rivals in order to distract him so he could kill Clover. Considers it 'cute' when children like Emerald, Mercury, Team RWBY or what's left of JNPR tries to fight back. Merciless serial killer. When he's upset, such as by disappointing Salem, he breaks down and finds something to stab over and over while he cries and laughs.

History: Was a serial killer who got arrested somewhere in Remnant. The warden said he needed to be watched closer, but was ignored. Salem appeared and destroyed the armored vehicle carrying him, and Tyrian declared her beautiful and started worshiping her right there. He became her loyal dog, tracking down targets and kidnapping or killing who was needed.

He's a member of Team WTCH under Salem but doesn't have any comradery with his teammates, only focusing on Salem. He finds his teammates, Cinder, Watts, and Hazel annoying at worst and fun to annoy at best. Salem sent him to track down the Spring Maiden, one of the four seasonal spirits of Remnant who's powers got sent to a new person every time the last one died. This one was Amber, and Tyrian tracked her down successfully so Cinder could attack her and take her powers. Next, Salem sent him to find Ruby Rose because of her silver eyes and the magic that came with them. He again tracked her successfully, but Ruby, Qrow, and Team JNPR fought back, holding their own through Tyrian's amusement.

He stung Qrow with his poison, and Ruby retaliated by cutting off his tail, throwing him off his game. He fled in rage and Watts had to make a prosthetic tail for him. Qrow survived, and the next time Tyrian saw him, it was when Salem sent him to assist in the downfall of Atlas. He played his part, got the information needed, killed Clover the head of the special forces team when Qrow tried to fight him, and then left for his desert mission. He also crashed a law enforcement vehicle and stole the pilot hat for fun.

He doesn't care that Salem's plan will end in world genocide and his own death. He just thinks it's great he can keep up his serial killer hobby and also see what happens when everything is destroyed.
