Kryten

Kryten is a Series 4000 mechanoid or "slave 'noid" — a robotic servant — and is quite neurotic. He is very humanoid, with the exception of the flat cubic planes visible on his face and head, and stands at 6 feet tall. Kryten's design is mostly plastic, but there are some slight organic elements in his construction.

Before Kryten left the Solar System, he was made to attend "toilet university", as he would remind people. This was revealed by Kristine Kochanski to be merely a piece of software which ensured Kryten was thorough in his cleaning of lavatories. Nevertheless he still had to take an exam to ensure that it was properly installed.

On CDC, Kryten and Aladeen have a special relationship. Special. Kryten's ability to find the perfect gif for the occasion is unparalleled.

His alter ego is Krpten.

In 2019, Kryten had a real-life near death experience but was saved by CDC Mafia.
