Three thousand years ago, Shockwave was the first Transformer to be reactivated, and set about restoring the planet and its populace, quietly working towards his own sinister ends. Unifying the Autobot and Decepticon factions, he appointed Ultra Magnus as his second-in-command, who led the attack on the Ark when they travelled to Earth and arrested Optimus Prime and Megatron as war criminals. (In reference to the theory that Ultra Magnus was formerly Dion, the name of the team Ultra Magnus led to take the Autobots into custody was team Dion.)
