O.M.N.S.S.

Omnipotent Multi-process Nexus Subuniversal Sentient, or O.M.N.S.S. (speak out as "Om-nus") is artificial intelligent computer, who appeared in the season 2 episode "The Mean Machines", voiced by Peter Renaday.

Shredder had already the second piece of the Eye of Sarnath, but had to hook it to a computer to unleash it's powers. He and Baxter broke into a high-tech lab, and found OMNSS and attached the second piece to it. Now under the command of Shredder, OMNSS tried to destroy the Turtles by sending self-driven vehicles after them, and later taking over the TurtleVan and tried to crash them, but they managed to stop it.

Shredder wanted to use OMNSS' powers to open a portal to Dimension X and get back his Foot Soldier, not longer needing the help of Krang. However the Turtles arrive and shut down OMNSS by simply pulling the plug. Shredder and Baxter unfortunately escaped.
