Udai Taxim

Udai Taxim is a character in the anime series Cowboy Bebop who serves as one of the antagonists in episode Black Dog Serenade, along with Fad. He is a psychotic and sadistic assassin who previously worked for European Syndicate before being arrested. He is Jet Black's arch-enemy and the one responsible for him losing an arm. His weapon of choice is throwing knives.

Story
Udai used to work of European Syndicate and was one of its most valuable members. One day, he was ordered to either kill or injure the former ISSP agent Jet Black for refusing to be part of the syndicate's pay roll. Udai conspired with Fad, Jet's partner, to take him down which resulted in him losing his left arm.

Sometime later, Udai was arrested and transferred on a prison ship to Pluto. Along with a group of prisoners, Udai manages to hijack the ship, slaughtering countless guards and the pilots in the process. After a brief argument with a violent, trigger-happy inmate, Udai takes command by slashing the inmate's throat and then sends his men to break through the police force which was surrounding them, killing them all.

When Jet and Fad board the ship, Udai decides to take Jet one-on-one. During the fight, Jet accuses Udai for losing his arm until Udai reveals that he wasn't the one to personally pull the trigger. He is subsequently betrayed and shot in the head by Fad before getting the chance to reveal Fad's involvement in Jet's injury.
