The Heppen-Bar Slitheen were a branch of the Raxacoricofallapatorian criminal family Slitheen.
History
Ecktosca and Dram tried many times to make a profit, disguising themselves as Meeps, Kraals and Martians. (PROSE: The Monsters Inside)
After many failed attempts to make profit, the fortunes of the Slitheen waned. They were put out of business by the Blathereen, who were cheaper and more effective. In the year 2501, Ecktosca and Dram were imprisoned on Justicia. However their Aunt Callis broke into Justicia to rescue them. They helped the Ninth Doctor stop the Blathereen's plan to turn Justicia into a planet destroyer. After the death of Don Arco, they stole the surviving warp-hole technology to rebuild their fortune.
