Prior to the initial Decepticon uprising, Autobot Energon Location Specialist Geosensus witnesses a deathmatch between Sting and Grabber in a makeshift arena deep within Cybertron.

Sting fought hard against the much-larger Grabber, having both arms badly damaged. At the last moment, he threw himself onto Grabber's sablade and used the momentum it imparted to topple both of them into the slag pit in the middle of the arena.

Though killed, Sting managed ot take his opponent with him. A worthy death by Decepticon standards.
