Brother Blood

Brother Blood is the charismatic and sadistic Headmaster of the H.I.V.E. Academy and the main antagonist of season 3. He is best known for being the arch nemesis of Cyborg.

History
Brother Blood first appeared in the episode "Deception" in which a disguised Cyborg was spying on the H.I.V.E. At that time, the H.I.V.E. students were conducting a series of robberies, which, as it turned out, served to finance the development of a prototype weapon called Ion Amplifier. Blood soon became aware of Cyborg's true identity and offered to make him human again if he served him. However, Cyborg demonstrated an unexpected immunity to Blood's mind control and, the power of his sonic cannon multiplied by the Amplifier, destroyed the entire H.I.V.E. Academy with only one shot.

However, it was later revealed that Blood had downloaded Cyborg's blueprints when the latter had hacked into the H.I.V.E computers. After having erected an underwater H.I.V.E. base just off the continental shelf, Brother Blood utilized Cyborg's sonic cannon schematics to build a massive underwater sonic resonator, which would create tidal waves strong enough to wipe out Jump City. After a failed solo attempt to stop the scheme, Aqualad alerted the Titans, who were also joined by another independent hero who had infiltrated the H.I.V.E., Bumblebee. Although the plot was foiled and Cyborg's blueprints recovered, Brother Blood's photographic memory allowed him to remain in possession of Cyborg's schematics, which he would employ later on in his attempts to rebuild the H.I.V.E.

Brother Blood retreated to Steel City, with a team of young independent heroes on his tail who would later be shaped by Cyborg into the Titans East team. After obtaining the security codes for Titans East Tower with the help of Steamroller, Blood and his robot troopers conducted a mass attack on the Titans East. While Cyborg apparently managed to evict Blood from the Tower, Blood had already gained two important footholds: he had already captured and taken control of the minds of Aqualad, Bumblebee, Más y Menos, and Speedy, recruiting them as his new "students", and hidden himself in the basement of the Tower, where he had himself converted into a cyborg by Professor Chang, who was mind controlled as well.

With the help of his brainwashed victims, Blood captured Cyborg for interrogation. In the course of their past confrontations, Cyborg's resistance to Blood's mind control had puzzled Blood. Thinking that this was due to a special gadget within Cyborg's systems he had not yet discovered, he intended to convert the Titans East into cyborgs as well for studying purposes. However, Cyborg had managed to call in his Titan friends, who freed him and engaged the Titans East in combat.

During the scuffle, Blood kidnapped Cyborg for a personal confrontation on the Tower's roof. After disabling Cyborg, Blood physically and psychically attempted to make Cyborg reveal the secret of his mental resistance. In the process, however, he unconsciously tapped too deeply into Cyborg's mind, and when Cyborg finally realized that it was actually his human mind and spirit which had enabled him to resist Blood, he exerted his will, tapping into Blood's powers in turn and using them to repair the damage inflicted on him, and then shattered Blood's cybernetic arms, rendering him helpless.

Following this crushing defeat, Blood was taken into custody. He was taken to prison and never been seen again.

Brother Blood is one of the few villains to not be seen joining the Brotherhood of Evil at the end of Homecoming - Part 2, along with Slade, Trigon, Krall, Soto, Blackfire, the Cironielian Chrysalis Eater, the Shrieker, and the White Monster.
