Editing Red Dwarf (section)

===Secondary Characters===
In addition to the four mainstay characters, Red Dwarf has played prolonged host to a handful of recurring secondary characters over the years.

'''Skutters:''' Little more than a three-fingered gripping claw on wheeled base, Skutters are the basic service mechanoids responsible for maintaining Red Dwarf in all of its nearly continent-sized glory. Not the brightest machines, but they do have distinct personalities, and are implied to play up how dumb they are in order to get one over on Rimmer, whom they hate. They get on much better with Lister, seeing a kindred spirit in him.

'''Holly:''' The ship's Artificial Intelligence, Holly basically runs the ship by himself, but doing it entirely on his own, and having been alone for 3 million years, has left him more than a little daft. He is a regular protagonist in the first two seasons, then undergoes a sex change and becomes a blonde-haired woman for seasons 3-5, during which time her senility seems to advance notably, as she's even dumber than the original Holly. During seasons 6 and 7, Holly is lost when Red Dwarf is stolen, whilst in seasons 10-12, he's been shorted out and doesn't interact with anyone.

'''Krystine Kochanski:''' The original Krystine Kochanski was a navigation officer aboard Red Dwarf; another British "lower class" girl who'd made something of herself by applying to Red Dwarf, whom Lister pined after from afar. Later it was retconned that she was an ex-girlfriend Lister wished to somehow gain back, because the writers thought that having him fixated on a girl who he never even asked out was too pathetic. During the events of season 7, a Krystine from a parallel dimension where ''she'' was Red Dwarf's lone survivor accidentally stumbles through a rift in dimensions and is inadvertently trapped on Starbug with the Boyz - much to her disgust. She stuck around for seasons 7 and 8, and then the movie "Back to Earth" established that she ran away to find a way back to her own dimension during the events of "the missing season 9", leaving Lister to think she was dead. This parallel Krystine is much more uppercrust and refined than her counterpart, but the two are treated as all but identical, since strong continuity isn't one of Red Dwarf's strongest points.

'''Ace Rimmer:''' A version of Rimmer from an alternate timeline where he actually managed to get over all his neuroses. "Ace" Rimmer is a brave and heroic starship pilot who was given the opportunity to test a ship capable of travelling between dimensions. The first dimension he travelled to was the prime Red Dwarf timeline, where he quickly befriended the crew and earned the resentment and envy of prime Rimmer. A later episode revealed that he became an [https://www.youtube.com/watch?v=gXYfnWRp1Q0 interdimensional hero], who upon his death would be succeeded by another timelines' Rimmer. This was used to write Rimmer out of the show for Season 7, as the duty now fell on him to become the new Ace (even though he is likely the worst of all possible Rimmers). One of the series' most memorable characters, even if he only appeared in three episodes.
