Cybingtons

Cybingtons are Cyborgised Money Spiders that were used as soldiers on Economyington. Their prowess in combat and terrifying appearance led to the near-annihilation of the Prowlers in the Great Credit Crunch, and after Economyington was destroyed Bankington took the blueprints for the Cybingtons to Earth with him.

After Bankington's death and the revelation of the Maths Mafia, Poundington used the blueprints for the Cybingtons to manufacture fleshless, robotic version in one of the many hidden rooms in the Crypt. They were deployed from a door that is otherwise never opened, that is padlocked from the outside and can only be opened by Poundington as his arms are the only key.

The Cybingtons aided in the Battle of the Distortion World but many were slain, and what few remained were swept aside by the Cybermen when they invaded part of the Crypt and recyled the Cybington technology to create a conversion facility in the school that the Crypt rests atop of.
