Harman is one of the three Space Pirates, a team of criminals who perform all kinds of hijacking of transports to steal their cargo and then sell them. They were operating in orbit around Earth raiding ships then selling the goods to the people on the planet. They were using delivery trucks as a cover with a purple penguin painted on the side. Their primary weapon is a harpoon system which delivers a computer virus which is capable of causing a ship's computer to act uncontrollably. They used this on Faye, Jet, and Ed messing up the Bebop, the Hammerhead, and the Redtail. They even got the virus past Ed. In order to defeat them, Spike had to unhook his ship from its computers and fly all manually.
Their virus was eventually turned against them and their ship burned up in the Earth's Atmosphere.
