WARNING: The following contains spoilers for Episode 10 of Mars Red, "A Midsummer Night's Dream Gone By," now streaming on Funimation.
While the main antagonist of Mars Red is still General Nakajima, his ally Deffrott is quickly surpassing him as the worst of the two, adding an unhinged twist to every evil act that he commits, not unlike a Joker with a Scottish accent. While he delighted in destroying his own kind and had a blast transforming innocent humans into brain-dead vampires, it was always in the name of Nakajima's plans. Even the "accident" that killed Misaki, Nakajima's own daughter, could have been justified as the best way to ensure that she wouldn't derail their plans to create super-vampire soldiers.
However, what was once a creative professional zeal has taken a turn into outright cruelty, even for Glenn. Instead of focusing on neutralizing Code Zero and their loved ones, In Episode 10, Glenn has chosen to make Deffrott's unlife specifically as difficult and tragic as he can. And not even for any apparent reason -- it seems Glenn just likes seeing Deffrott squirm.
Deffrott, an ancient child vampire who works as an actor in the Imperial Theater, knows everything about Nakajima's plans and Glenn's involvement. He was Misaki's friend and had recently turned Maeda -- Nakajima's former right-hand man -- into a sulky vampire, but Glenn doesn't know that. To Glenn, Deffrott was just the resident European vampire when he arrived in Tokyo. His targeting Deffrott doesn't truly seem to have any goal besides simply hurting him.
But this isn't exactly surprising. Glenn's polite facade hides a murderous nature, the exact opposite of Deffrott's grumpy demeanor and soft heart. Glenn licks his lips with anticipation whenever he spots potential prey -- but mostly when he sees Deffrott. Deffrott couldn't care less about Glenn, but Glenn forces him to by kidnapping his only remaining sort-of-friend, Aoi Shirase, luring an incredulous and very tired Deffrott to a bunker with an automated ceiling and trying to expose him to sunlight.
Then again, maybe Glenn has a thing for killing kids. After all, he did kill a child vampire to make Maeda turn against Sowa, who is himself a child vampire. His first on-screen victim is Misaki, barely out of childhood herself, and he wouldn't mind disposing of Aoi, who is about Misaki's age. Deffrott is simply the most powerful child, a true challenge.
And, again, from this angle, the brutal transformation of human children into immortal vampires through Glenn's vaccine +also makes sense. While Nakajima would have wanted grown-up super soldiers for his army and a credible menace at home, turning kids into immortal, forever hungry bloodsuckers would have been a very dumb idea -- nobody would want to kill children or to witness the killing of children, and any support for his grand scheme would have fallen through. Unless, of course, they were Rufus Glenn, who didn't so much care about the grand scheme as about causing chaos and targeting tots.
