Anchor Blue was known as a powerful Houk gladiator of the male gender. He fought in the chaotic free-for-all gladiatorial matches held within the Cauldron on the planet Rattatak. His combat prowess wasn't only due to his considerable size and raw power.
Anchor Blue, a Rattataki gladiator, had a device implanted in his vibroblade by his patron. This device was used to control him. His patron could activate an electrical pulse via remote control, causing extreme pain throughout Blue's body. This pain fueled an intense rage during arena battles, transforming him into a lethal opponent. Conversely, a different setting on the device could inject sedatives into Blue's system, pacifying him. These sedatives led to an addiction, giving his patron absolute command over the gladiator.
Ultimately, he met his demise in the arena, falling victim to Asajj Ventress during the battle that marked her rise as Count Dooku's apprentice.
