Karter is a tall elderly Chinese-American man with black eyes, messy grey hair and a full grey beard. He wore a Plumber suit for most of Big Plans, but appeared near the end of the episode with black Proto-Tech armor, which he also wore in Verge.
Karter is almost always grumpy and is often rude to others, especially those who work for him.
Prior to Bonds
Karter joined the Plumbers in 1943, at the age of 28. He was involved in the event that led to the intergalactic version of the Plumbers, Liberation, renaming themselves, and played a part in stopping Vilgax's activities on Earth in the 1960s and 1970s. This led to him being promoted to Magister and eventually, Magister of Earth. He was also recruited into the Rooters.
When Servantis became a Plumber, Magister Chang took note of his skills in experimenting on aliens, especially during his failed attempt to give himself Cerebrocrustacean DNA. The Rooters became interested in using him for their own gain. Around this time, Magister Chang also decided that he wanted to put more focus on his duty as a Rooter instead of continuing to be the Magister of Earth.
When a fresh Plumber Academy graduate named Lal'Ek was informed in advance about her first mission to capture Dr. Psychobos, she was contacted by the Rooters, who tasked her with ensuring Dr. Psychobos would crash on Earth so that he could be experimented on by Servantis, as part of their plan to have Servantis sent to the Null Void so he could work for them. She set up a deal with Servantis to bring him Dr. Psychobos, with Servantis thinking it was his plan all along.
In Big Plans, after Lal'Ek and her squad made Dr. Psychobos crash on Earth, Servantis was told to treat his injuries. He took the opportunity to extract Dr. Psychobos' DNA and merge it with his own to stabilize himself. He was caught by Magister Chang, who intended to send him to the Null Void. Magister Gilhil then contacted one of the members of Lal'Ek's squad, Wysaq, and was brought up to speed on the situation. He argued with Magister Chang about what to do with Servantis. Magister Chang wanted to send him to Null Void (to fulfil the Rooters' plan), while Magister Gilhil wanted him detained for questioning. Magister Chang disobeyed Magister Gilhil's orders and sent him to the Null Void. Magister Gilhil then fired Magister Chang and had him imprisoned in the Null Void, just as Magister Chang had hoped.
Magister Chang, along with Magister Coronach and Magister Gorvan, approached Servantis a few days after he was imprisoned in the Null Void. They explained that they hired Lal'Ek to get in contact with him so that he would experiment on Dr. Psychobos and subsequently get sent to the Null Void. They revealed that they had been watching him for some time and that they wanted to exploit his skills in alien experimentation by putting him in-charge of the Null Void's branch of Incarcecon. He refused, but was swayed to obey them when they threatened to kill his friend, Adriel Albright. Deeming Adriel's life more important than his own freedom, Servantis relented.
21 years later, in Verge, a bounty hunter named Disease found Trystan Wheels, for whom the Rooters had issued a manhunt in 1994, on Revonnah and brought him to an undisclosed location. The Rooters retrieved him and brought him back to Rooter Headquarters. Not wanting to split their attention between Trystan and the Amalgam Kids, they canceled the kids' next mission and ordered Servantis to break the news. Magister Chang joined the other Rooters in a meeting where Magister Wheels, Trystan's wife and a member of the Rooters, offered to kill Trystan. Dissatisfied with the explanation given to them on why their mission was canceled, the kids decided to snoop around to get answers by disabling the camera in the elevator to access the restricted levels.
Magister Gorvan made an announcement that Helen had taken Trystan out of the interrogation room in which he was held, and Magister Chang set out to find her with Phil. They soon found Servantis, Magister Coronach and the Amalgam Kids in the operating room (with Helen and Pierce unconscious) and demanded to know the truth, but Servantis and Magister Coronach lied. Magister Gorvan came shortly after that and revealed that he found Magister Wheels' body, and that he killed Trystan. To balance the scales, he intended to kill Servantis and the Amalgam Kids, as he claimed they were of no use because Magister Wheels, who came up with the idea in the first place, was dead. Magister Chang agreed, but Magister Coronach and Phil did not. Phil transformed into his Terroranchula form and trapped Magister Chang in a web before engaging in a battle with Magister Gorvan with Alan's help.
Magister Gorvan eventually lost and the Amalgam Kids were sent to Earth. Magister Chang later participated in a meeting with the other Rooters. Much to his dismay, Servantis was present as well as an official member, replacing Magister Wheels. Magister Leander arrived late, bringing with him Magistrata Latdu. She explained that she used to be a Rooter herself, but she left to focus on the Plumbers as a whole. Displeased with the direction the Rooters had gone in her absence, she officially declared herself the leader and intended to make major changes. Intrigued by Servantis' role in the organization, she urged him to tell her everything that had transpired since he was forced to work for them.
Magister Chang was later fired from both the Plumbers and the Rooters.
