Warp Darkmatter (voiced by Diedrich Bader) was once Buzz's partner and friend, but he had been secretly working for Zurg since his academy days as a double agent. He eventually began working for him full-time as "Agent Z." His right arm is robotic (with various weapon attachments) and was grafted to his body after becoming Agent Z. Warp often takes on assignments for Zurg and is paid quite handsomely. (He owns a moon and a summer home.) Though Buzz has vowed to bring him in for treason, he retains some hope that there is still some good in him.
