SDCC 2013 Transformers Prime Shockwave's Lab by Hasbro

Deep within a secret facility, Shockwave labored, pushing Decepticon science to its absolute limits and beyond. His discovery of ancient Cybertronian genetic material led him to discovery after discovery, until he was able to realize a dream - one that would become an apocalyptic nightmare for the Autobots. It was there in that lab that Shockwave created his masterpiece - the resurrection of the mighty, remorseless and barbarous Predaking.
