Ultrabot 4000

Ultrabot 4000 Observation Units

The Ultrabot 4000 Observation Units were robotic surveillance units invented by Ultrabot 2000 which could supposedly increase productivity in Dexter's Lab, but in truth they were destructive laser turrets designed to help Ultrabot in destroying Dexter and anything he deemed obsolete. Luckily Ultrabot and his units were destroyed thanks to Dee Dee's foolishness, which confused them so much that they destroyed themselves after destroying Ultrabot.
