Anchor Blue's Rattataki patron installed a sinister device in the base of the Houk's vibroblade. At a touch from his remote control, an electrical pulse would send searing pain through Blue's body. While in the arena, pain-induced rage made him a deadly fighter. Another setting would pump sedatives into Blue's bloodstream, calming him. Blue eventually became addicted to these sedatives, which allowed his patron total control over the gladiator.
