It is the year 2011. A treacherous Decepticon group long thought to have been lost to the cosmos have resurfaced, bringing the threat of a new war to both Earth and Cybertron. The Autobots have a new weapon in the fight though... A mysterious new friend who calls himself Depth Charge. This new ally was found by a human exploration crew, frozen in the depths of the Atlantic. It didn't take long for the Autobots to be alerted to what was found to be a cybertronian warrior who had lived on Earth millions of years ago. After much work, Ratchet was able to rebuild and reactivate the oddly advanced robotic life form, who claimed to be a "Maximal", from 300 years in the future! Depth Charge doesn't talk much, and refuses to talk about his past, or the future, saying only that he closed that chapter of his life and does not look back. With a new Autobot body fused with alien transmetal parts and advanced Maximal circuitry, Depth Charge is the silent killer to send when you need a con to disappear.
