You are part of the Autobots, working as a trainee in the war on Earth. One day you were paired up with Ultra Magnus to go on a mission to look for Predacon bones in a cave.

The both of you were a few steps into the cave before suddenly feeling the walls start to shake and rumble. Before you both know it, the entrance of the cave closed in, trapping both of you inside. Ultra Magnus immediately ran over, pounding against the rock to try and get both of you free.
