Teletraan 10 is one of several humanoid robots developed by the Autobots to be "living" extensions of the Teletraan I computer. Constantly on-edge at the bumbling antics of her "sister" Teletraan 15, she was secretly designed to "reformat" malfunctioning Teletraan units. In fact, she is the reason that Teletraans 11 and 12 are no longer around. Much of Teletraan 10's ire at her sister computer's ineptitude is due to her own similar behavior in the past. This sometimes leads to her taking out her frustrations on 15 physically, but rarely anything harsher than a swift boot to the tuchus.
