Low Rimmer was a version of Arnold Rimmer created by the Triplicator.

He had all of his positive aspects removed. He was sadistic and seemed to enjoy causing pain sexually. He wore fetish gear including a corset, a spiked collar and stockings and wielded a holowhip . He appears to be gay or bisexual judging by his remarks to Lister.

He was destroyed when the triplicator remade Red Dwarf from the two versions. (RD: Demons & Angels)
