Tazer

Tazer is an evil robot with the mind of a young adult that is a secondary antagonist in the PlayStation All-Stars series. Despite being a character in the Rez mythos, he wasn't seen or mentioned at any point in the two games, only being shown in this series.

Biography
Tazer was a robot created by Olga's classmate Jimmy as part of the same school project Swayzak was created for. Being a sentient robot, Tazer was especially fond of hanging out at Jimmy's and Olga's dorm rooms, eating snacks and watching cartoons, and he dreamed of being much more than just a robot, as he was able to make moral decisions. He admired Eden greatly.

One day, Tazer woke up in the warehouse Jimmy called home, levitating in the air, engulfed in a field of electricity. Upon further investigation, Tazer discovered he had electrokinesis after unsupervised contact with a potentially unsafe wire. Wanting to use these powers for good, Tazer set to work mastering them.

This all changed when Swayzak gained evilness and started targeting systems to infect and ruin. Swayzak secretly infected Tazer, unbeknownst to the poor robot, and amplified characteristics in him, including aggression. Jimmy returned home to see his warehouse completely disheveled, with Tazer warning him not to come any closer. The robot revealed he'd been infected, and tried to kill Jimmy with his frighteningly mastered electrokinesis. Jimmy ran away from his warehouse, never to return.

Tazer then inhabited the space Jimmy used to live in, plotting crimes, that would be put to an end by the police. However, since the first law of robotics said a robot could never harm a human, the police were forced to comply with the opposite, and they blocked any robot hunter from slaying him.

PlayStation All-Stars
Tazer is one of the secondary antagonists in the second season, starting with the episode "It's All Coming Back to Me Now." Prior to this episode, Swayzak had forgotten all about Tazer, as he became so engrossed in his good program nature that he paid no attention to his past evil deeds.

Eden encounters Tazer when she's searching for the location of the Yexxens' next attack. Tazer threatens Eden, and is about to shock her with his powers when she hacks into his mind and shuts him down. Eden takes the bot back to the base in order to examine him. There, she finds a familiar signature embedded into his head, and she immediately contacts Swayzak to ask about his relation to this robot. Forced to remember one of his villainous acts, Swayzak confesses that Tazer was formerly a good robot, but became evil when he infected him. When asked why he can't disinfect him, Swayzak says there is no hope for him and that he's been ruined to the point any repairs made to him would take a very long time.

The rest of the episode is about Swayzak going on a guilt trip and realizing his villainy may soon resurface if he doesn't do anything soon, but Tazer reactivates at the end of the episode and Art uses Imp to create handcuffs for him, turning him in to the police.

Personality
Tazer is a sadistic, sarcastic robot, taking pride in doing harm to others and thinking evil feels good. As flashbacks to his past show, he initially was conflicted between continuing his path of villainy or breaking free from the infection; the infection was like a high to him, and he struggled to keep on his feet. However, the infection overtook his mind completely, and he had no qualms about the morality of what he was doing soon enough.

Also to note about Tazer is that he loves The Phantom of the Opera and murder mysteries; he is bisexual too.

Trivia

 * Tazer was based on TOM 2 from Cartoon Network's Toonami. Rez lore owes a lot to Toonami because of the 2004 review of the PlayStation 2 port which featured Swayzak, so it's only natural there'd be a character based on TOM as Swayzak is Swayzak and Eden and the protagonist of Child of Eden is Sara. Tazer is based on evil TOM 2 from the Trapped in Hyperspace game, who was the result of Swayzak infecting TOM in the final stage.
 * Tazer was originally conceived for a possible revival of the DisneyQuest game Ride the Comix. When Konnichiku started hating Disney, they took Tazer with them and eventually put them in the Rez universe.
