<Li> Shockwave (voiced by Frank Welker in the film, Steven Blum in Rise of the Dark Spark) is an emotional Decepticon assassin . He is killed in the Battle of Chicago by Optimus . Shockwave transforms into a Cybertronian self - propelled artillery vehicle . Like his original G1 appearance, Shockwave's head features a single red eye, and has a gun in place of one of his hands, with a tube connecting it to his back . Visual effects supervisor Scott Farrar said that the lack of eyes and mouth in Shockwave's design means "you have to read Shockwave through just the emotions of his face, almost like a silent - era film star," which caused the eye to have an intrinsic design, with a lens, a moving iris and an oscillating light . <Ul> <Li> The Driller is Shockwave's pet . It is a giant, tentacled Mongolian death worm - like Cybertronian creature, which is used for drilling purposes . It is also Cybertron's most feared predator . The Driller appeared, attacking and killing NEST soldiers, tried to get the engine part of the Ark, but Optimus stops it and retreats . Later in the Battle of Chicago, Shockwave commands his pet to tear down a large building, but the beast is decapitated and killed by Optimus Prime . </Li> </Ul> </Li> <Ul> <Li> The Driller is Shockwave's pet .
