SPOILER WARNING: This article contains major spoilers for "Dangerous Liaisons," the latest episode of Supergirl.
Welcome back to the Arrowverse, Phil LaMarr!
In "Dangerous Liaisons," the latest episode of Supergirl, the Justice League Unlimited star made a live-action appearance on the series. He played the human form of Malefic, J'onn J'onnz's Martian brother.
Last week, Lena Luthor tricked the DEO into surrendering Malefic to her lab. She helped Brainiac-5 work on a device that would allegedly transport Malefic back to the Phantom Zone. However, she sneakily retooled it so that he would be sent to the containment cell in her lab instead. So, when the episode picked up, she had Malefic in her custody. She induced his human form so that she might be able to map his brain.
When Lena induced Malefic's human form, he appeared as LaMarr. LaMarr, of course, has voiced the character since his introduction in the Season 4 finale. However, this is the first time he has appeared as himself on-screen during the series. It is unclear if he has stood in for Malefic's Martian form during filming before this point.
Throughout the episode, Lena conducted experiments on Malefic to study his power of induction, which allows him to control other people. He allowed her to do so on the condition that she would help him kill J'onn. However, she went back on her word at the end of the episode. "I could never let you hurt another person," she said.
"We had a deal," Malefic insisted, enraged. When Lena stood her ground, he charged at her, but she stopped him dead in his tracks. Using Obsidian North's virtual reality technology and the Q-wave theory she had discovered from her research, she turned his powers back on him and induced him.
Her eyes glowing green, she said, "You like it here, don't you?"
Malefic's face went blank. "Yes," he agreed. "I like it here. I like it very much." With that, it seems Lena has the Martian fully under her control.
Though this is his first live-action appearance, LaMarr is no stranger to the Arrowverse. He also voiced Rag Doll in two episodes of The Flash, while contortionist Troy James physically portrayed the character. As such, this Supergirl episode is LaMarr's first live-action appearance in the Arrowverse.
LeMarr is perhaps best known as a voice actor. He has lent his voice to various DC properties, like Justice League Unlimited, DC Super Hero Girls, Superman: Red Son, Young Justice and Batman Unlimited. His previous credits also include Avengers: Earth's Mightiest Heroes, Avengers Assemble, Star Wars Rebels, Star Wars: The Clone Wars, The Spectacular Spider-Man, Wolverine and the X-Men and much, much more.
Airing Sundays at 9 p.m. ET/PT on The CW, Supergirl stars Melissa Benoist as Kara Danvers, David Harewood as Martian Manhunter, Mehcad Brooks as Jimmy Olsen and Chyler Leigh as Alex Danvers.
