Character description from package "tech spec": The youngest Autobot assigned to the Eight track, Kup hides his eagerness and inexperience behind adherence to the command structure and protocol.  Kup seeks to emulate his Captain and mentor, thunderclash, but also looks up to Landshark due to his unorthadox approach.  He can't help but be in awe of both his comrades and all the new worlds he has visited serving aboard the eight track.  A manufacturing glitch gave Kup's joints the ability to detach and re-attach without causing permanent damage to his superstructure.  this give him surprising resillience and makes him exceptionally easy to repair.  this ability also lets him swap out his hand for a top fo teh line laser musket and other useful tools.  His lack of experience often leaves him vulnerable, but he is as brave and loyal as they come.
