Frederick Sanguine was a former soldier who developed an unhealthy appreciation for the art of war. Raised in the latter years of the Cold War era, Sanguine learned about various brainwashing techniques conducted by American military forces. He acquired several devices and secured himself a hidden Cold War bunker buried one mile beneath the island of Manhattan in New York City. With a private army under his command and a new objective in mind, Sanguine adopted the costumed alias of Commander Blud.
Commander Blud learned that one of New York's transitory super-heroes, the time-lost Karate Kid, possessed keen knowledge of the future. He instructed his soldiers to strike during a Bicentennial parade, wherein they abducted Karate Kid's friend, Iris Jacobs.
The Karate Kid tracked Iris to Blud's underground bunker, but fell into a trap. Blud wanted Karate Kid to tell him comprehensive details concerning Earth's next World War. He cared little for the politics involved in such a future endeavor, but merely wanted to be present so that he could immerse himself in the glory of battle. Karate Kid refused to aid him, and the two began fighting. Initially Blud maintained the upper hand over Kid, but he inadvertently drove the hero into a berserker frenzy. Ultimately, Commander Blud was defeated.
- This version of Commander Blud, including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
- Base of Operations: Manhattan, New York City
- Equipment: Commander Blud wears a pair of studded steel gauntlets, which provide him with additional strength during melee battle. He also uses a special torture device, the design of which is based on military brainwashing tools used during the Cold War.
