Warp Darkmatter

Warp Darkmatter was once a Space Ranger who was secretly working as a double agent for the Evil Emperor Zurg for close to twenty years. After feigning his death, he went on to work for Zurg, acquiring the short-lived moniker "Agent Z" before he was discovered and opted to openly commit crimes under his actual name.

Physical Appearance
Warp has light blue skin and dark blue hair he keeps cropped short, flanked by sideburns. He sports a chin-strip beard and he has sharp, squarish features. He is broad-shouldered and muscular, and is usually seen wearing body armor colored red and purple. After losing his right arm, he now possesses a cyber-biotic[1] arm with four claws that can morph into an array of weapons, including a flamethrower.

History
Very little is known about Warp Darkmatter prior to him signing up to the Space Ranger Academy.

Warp Darkmatter was the partner to Buzz Lightyear, and the two worked well together, becoming a top notch team and best friends. One day, while searching a moon for three Little Green Men (LGMs), that had gone missing, they discovered a hidden base belonging to Evil Emperor Zurg, who had kidnapped the LGMs.

Buzz and Warp rescued the LGMs, but Zurg activated the bases self-destruct on his way out, and Warp ended up pinned under rubble caused by the fight, Buzz tried to free his friend, but Warp insisted that he leave him behind and get the LGMs to safety. Buzz refused, causing Warp to activate Buzz's rocket pack, propelling him out, just as the lair exploded, seemingly killing Warp.

Agent Z
Warp was not killed in the explosion, as everyone had thought. Instead, Zurg took him back to Planet Z and had him rebuilt with cybernetic parts to become his new top henchman, Agent Z.

He then sent Warp out to the home planet of the LGMs to steal the Uni-Mind, the mystical orb that links all the LGMs together, Buzz and his new robot partner XR arrived on the scene, but with Warp's knowledge of Buzz's fighting style and moves, he easily escaped with the Uni-Mind.

During the final battle to stop Zurg from using the Uni-Mind to control every mind in the galaxy, Warp revealed himself to Buzz, and also revealed that he had been working for Zurg since the Space Ranger Academy, and that once he learned of the Uni-Mind, he and Zurg set up the explosion to allow Warp to leave Star Command and come work for Zurg full time.

After Zurg was stopped, Warp escaped and has frequently clashed with Buzz while completing missions for Zurg.
