Ferrotaxis

The Ferrotaxis is a powerful Cybertronian supercomputer.

Transformers: Devastation
It was created long ago where it was installed onboard Nova Prime's starship the Proudstar. The Ferrotaxis had the Colonnade of Cybertron embedded within it that was the sum total of Cybertronian culture. In addition, the computer was linked to the vessel's Insecticon swarm that were used for cyberforming worlds and the Plasma Core that powered the ship. Millions of years ago, Nova Prime encountered a dark force that corrupted him and led him to seek the destruction of other planets. The Proudstar would later crash on the primitive world of Earth and remain buried there until the Great War between the Autobot's and the Decepticons. Megatron recovered the Proudstar and used the Ferrotaxis to command the Insecticons to cyberform Earth. Optimus Prime and the Autobots sought to stop him as well as recover the supercomputer in order to save the Colonnade. However, Megatron introduced a failsafe on the Ferrotaxis that meant that its command over the Insecticons to cyberform Earth would only cease with its destruction. As a result, Optimus Prime had no choice but to destroy the Ferrotaxis and the Colonnade thus saving Earth.
