Brother Blood appears in the Teen Titans animated series, voiced by John DiMaggio, as the main antagonist of Season 3. In the show, Brother Blood is the charismatic - and sadistic - Headmaster of the H.I.V.E. Academy. He is a powerful psychic who mind controls his students to keep them under his thrall. Blood shows using his psychic powers for a variety of other purposes as well, such as deadly force bolts; telekinesis; alter another's perception; enhance his punches; reflect attacks; and teleportation. In addition, Blood displays formidable fighting skills. Brother Blood is sometimes considered to be Slade's temporary replacement after the latter's "death" in season two despite their conflicting personality traits. He is also the only one who can frighten Jynx, Gizmo, and Mammoth. He acted like Cyborg's biggest enemy in that same season.
History
Brother Blood, before becoming a cyborg
Brother Blood first appearance in the episode "Deception" in which a disguised Cyborg is spying on the H.I.V.E. Blood is aware of his true identity and offers to make him human if he serves him. In the end Cyborg shows that he is immune to Blood's mind control because half of his brain is mechanical, and destroys the entire H.I.V.E. Academy thanks to a power upgrade provided by Blood. However, the H.I.V.E had downloaded Cyborg's blueprints when the latter hacked into the H.I.V.E computers, allowing Brother Blood to know Cyborg's weaknesses; in the episode "Wavelength", Brother Blood has utilized Cyborg's sonic cannon schematics to build a massive underwater sonic resonator strong enough to wipe out Jump City. Although the plot is foiled and Cyborg's blueprints are taken back, Brother Blood later reveals that he possesses a photographic memory, thus, he remembers every detail of the blueprints.
Brother Blood's defeat
Brother Blood's final appearance is in the two-part episode "Titans East"; he takes control over the minds of Aqualad, Bumblebee, Más y Menos, and Speedy and has them re-build the Titans East tower into his new headquarters. Blood also converts himself into a cyborg to enhance his mental abilities and plans to turn the Titans East into cyborgs as well so he can control them completely. Brother Blood is ultimatly defeated by Cyborg when the hero reveals that it is actually his human spirit that enables him to defy Blood's control.
Powers and Abilities
Blood is not only a master of controlling the minds of even other superhumans, but possesses considerable skill in physical combat, able to project deadly force bolts or altering perception. In his first appearance, he displayed the ability to make Cyborg believe he transformed Cyborg's metal hand into flesh, though this only fooled the organic side of his brain; Cyborg's mechanical sensors saw through the trick. In addition, Blood displays formidable fighting skills. Because Cyborg was immune to his mind control, Blood developed something of a rivalry with him, even though he easily defeated Cyborg in most of their fights since he knew all of his weakspots.
Production Notes
Producer/writer David Slack stated saying: "In the end, we tried to make him the anti-Slade. Where Slade hides in the shadows, Brother Blood loves the spotlight. Slade always has some ulterior motive, Brother Blood will tell you what he's planning right away. So there's some contrast there. [...]We weren't even sure we'd get to use that name. I think what was important that we kept was that he was the leader of a cult. We kept that role and drew inspiration from cult leaders we read about. They are very charming seeming people. From that, we gave him this sort of 'power of temptation' - this ability to control people's perceptions. And the power of persuasion. We didn't get too deep into the character from the comics, because so much of it was so outside of what we'd be able to do. He's definitely one where we've strayed more."
