While this shell failed to take control of the Autobot leader, it let Soundwave and Megatron tap into his thoughts, alongside the power of the Creation Matrix, which Megatron used to give life to the Stunticons. While the plan was foiled, Bombshell attached himself to Silverbolt and got into the Ark undetected, where he implanted another cerebro-shell into an open wound on Optimus Prime. Their plan proceeded smoothly until the Aerialbots attacked, and Vasquez managed to overcome the cerebro-shell by thinking about his love for his daughter. Bombshell showed Megatron the power of his shells by ordering the human to lick dirt off his foot, and Megatron and the Insecticons had a jolly good time when Vasquez complied.
In a plot to steal energy from Hoover Dam, Megatron ordered Bombshell to implant a cerebro-shell in the brain of Ricky Vasquez, a worker at the dam. They have the power to control the minds of both humans and Transformers if injected into their brains. Cerebro-shells are devices used by the Decepticon Bombshell.
