Arnold J. Rimmer

Arnold Judas Rimmer is a fictional character in the science fiction situation comedy Red Dwarf. Rimmer is a snobbish and self-centered character, Rimmer is unpopular with his crewmates, and is often the target of insults and general ridicule. After he is killed by a radiation leak during a timeskip in the series' first episode "The End" (1988) Rimmer is present for most of the series as a computer-generated hologram, indicated by the ‘H’ symbol on his forehead. From series I-V, Rimmer is intangible as a hologram and unable to interact with his environment, referred to in-universe as 'soft-light'; come the series VI episode "Legion" (1993), Rimmer is upgraded as a 'hard-light' hologram where he is now able to interact with his surroundings as well as being essentially indestructible, yet still able to feel pain.
