Under-3 is a fictional character from the Transformers series. He is also known as Unit-3.
Unit-3 helps forms the right leg of Magnaboss. He may or may not have been to Autobot Laster.
According to a 1995 McDonalds Beast Wars document, Under-3 was intended to be Optimus Prime.
The Maximal known now only as Unit-3 is the surviving member of the similarly named battalion. Shocked from the trauma, he has buried all earlier personality traits under three quadruple-encrypted layers in his central processing system and now only responds to his new, self-appointed designation. His commander, Prowl, has tried to find methods to restore the buried personality algorithms but has only found scraps of fragmented information. Secretly though, Prowl appreciates him as the perfect soldier who will follow orders with a lion's heart and a head that understands the chain of command. Unit-3 is a data collection specialist, sent on special assignments where other investigators have come up empty. His sensors can detect odors and sounds from vast distances and analyze trace chemical contaminates in single parts per billion. Banks of processors hidden throughout his alternate mode allow him to store and process more information than most other robots.
Unit-3 was assigned to an Autobot/Maximal unit that included Perceptor, but all the other members of his unit were slaughtered; he thus dubbed himself "Unit-3" as the only survivor. As a result, the Primal Council decided to incorporate him into the Magnaboss Combiner, which also included Ironhide, Prowl, Silverbolt and Tigatron. The five eventually formed this Combiner in order to battle the forces led by TM3 Megatron; shortly afterwards the Great War ended with a truce between the two sides.
