Wake up! You don't want to miss the pain! Can you feel the needles as they burrow into your spine?
~ Low Kryten to Lister

Low Kryten is one of the main antagonists from the Red Dwarf episode Demons and Angels. He was created by a Triplicator as a worse version of Kryten.

He is portrayed by Robert Llewellyn.


Low Kryten is an android, but visibly worn out, as he is covered in oil and stammers while speaking. He wears a spiked collar and gloves and his voice is rasping and pitched lower than the original Kryten's one. He obviously lost his guilt and behavior chips, causing him to be sadistic, callous and to enjoy hurting others. He is stronger than the original, as he is able to punch his arms though a wall to strangle Lister. He is also the one who place a spinal implant into Lister's neck to control his actions.


When the Triplicator creates two versions of Red Dwarf ship and its crew, Low Kryten appears on the Low one with his friends Low Lister, Low Rimmer, Low Cat and Low Holly. As nothing works on their ship, they decide to get the High one and send a fake call for help to decoy High versions of them.

Meanwhile, the original crew lands on the High ship to get the Triplicator, only to find out there is only half of it, so nevertheless to the help call, they have to go to the Low ship.

After the original crew and High versions of them land on the Low ship, they are immediately attacked by Lows who shoot High Kryten several times and then blow him and the High Cat by a grenade. Lister runs off into the cargo bay where he bumps into the Lows. After Low Rimmer hits him with a Holowhip, he faints off.

Later, Lister wakes up, only to find out the Lows place an implant into his spine that allows them to control his actions. They force him to shut his nose in a cupboard, burn his groin with hot coffee and eat a tarantula. They then give him a knife and send him to kill his friends. Under their control, Lister stabs High Lister and crush High Rimmer's Light Bee. Luckily, Kryten manages to chloroform Lister before he can kill anyone else.

After the original crew leaves the Low ship in the Starbug, they destroy the both duplicates with now completed Triplicator, causing all the Lows disappear (except Low Lister who hides in the Starbug).


  • He and other Lows have visibly better relationships that the original crew.
