"Watch it, fleshing! When I want my feet licked, I’ll ask for it!
...I want my feet licked."

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. Bombshell showed Megatron the power of his shells by ordering the human to lick the dirt off his foot, and Megatron and the Insecticons had a jolly good time when Vasquez complied. Their plan proceeded smoothly until the Aerialbots attacked, and Vasquez managed to overcome the cerebro-shell by thinking about his love for his daughter. 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. 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. Aerialbots over America! Wheeljack later removed the cerebro-shell from Optimus Prime's skull and modified it to let the Autobots listen in on the Decepticons' plans instead. Afterdeath!

When Bombshell and Dirge were ordered to take control of Power Station Alpha, they discovered Bumblebee watching it on behalf of the Autobots. To distract him, Bombshell fired a cerebro-shell into young Anthony Duranti and ordered him to stand in front of the station's tracks during launch. Bumblebee was forced to transform and rescue him, which led to him being shot and killed by G.I. Joe for being a giant robot. Blood on the Tracks Bombshell then infiltrated Power Station Alpha and planted a special cerebro-shell in its mainframe, which let Shockwave control it back to the Decepticon base. However, Doctor Mindbender of Cobra managed to lock onto the shell's electronic frequency and control the station over to the Cobra base instead. Meanwhile, Anthony, whom Bombshell apparently forgot about after he served his purpose, had become completely unresponsive, so his mother took him to a doctor, who spotted the cerebro-shell via x-ray. Power Struggle

The shell was surgically removed by Doctor McGrath and Duranti returned to normal, while McGrath started prodding the shell while trying to figure out exactly what it was. This caused Bombshell to spasm and transform out of his own control back at Decepticon headquarters, although he only suspected some generic circuit malfunctions. Ashes, Ashes... The shell eventually ended up in the hands of Mainframe of G.I. Joe, whom also started prodding it. The deactivated Bombshell, who'd been brought into the very same room as the shell by Doctor Mindbender, started spasming again, and everyone found this very interesting. ...All Fall Down!

Transformers Annual 1985

Due to being published early in the franchise, these stories are out of continuity with the above.

Upon learning of a potential alliance between the Autobots and the President of the United States, Megatron awakened the Insecticons and sent them to disrupt the meeting, under the direct mental control of Ravage. During the mission, Bombshell launched a cerebro-shell towards Optimus Prime just as Kickback destroyed his Roller drone, which caused Optimus to keel over in pain. Instead of the Autobot leader, Bombshell injected Ravage with the cerebro-shell, but since Ravage was already in control of Bombshell's mind, the end result was two Decepticons left mindless and immobile. Plague of the Insecticons!

These stories do not fit into the normal Marvel continuity. See Earthforce for details.

In an attempt to ruin the Autobots' reputation amongst humans, Bombshell later injected Superion with a cerebro-shell, forcing the massive combiner to rampage through New York City. However, the Autobots recruited a reporter by the name of Irwin Spoon to climb inside Superion and remove the shell. Inside Story! Unfortunately, Irwin never got a chance to share this experience with the world, as Bombshell simply injected him with another cerebro-shell and made him write mudslinging stories about the Autobots instead. End of the Road!

Bug Bite reversed-engineered cerebro-shell technology in order to control the minds of his fellow Decepticons and take leadership of them. This worked out great until the signals from the shells were jammed by Autobots, and Bug Bite was shot by Megatron, who was immune to cerebro-shells anyway. A noteworthy innovation from Bug Bite's variation on the technology was that he modified his cerebro-shells to fit into the standard bore of Decepticon weaponry, presumably breaking the monopoly Bombshell had upon his signature weapon. Games of Deception

Generation 1 cartoon continuity

The Transformers cartoon

After being caught in a battle of misunderstanding between the Insecticons and Megatron's Decepticons, Mirage was left sitting unconscious in a wasteland, where the Insecticons found him. Bombshell implanted a cerebro-shell in him, effectively turning Mirage into a slave to use against the other Decepticons (whom the Insecticons considered enemies at the time, due to the aforementioned misunderstanding). When the two groups settled their differences, Megatron used Mirage to lead the Autobots into a trap. Cliffjumper punched the traitor's lights out in the ensuing battle, and Ratchet found and removed the cerebro-shell when examining him afterwards. Traitor

The Insecticons later devoured the Nova Power Core, which greatly increased their size and power. They decided that with this power, they didn't need to remain with Megatron anymore, and when Soundwave overheard their conversation, he was spotted and injected with a cerebro-shell. The Insecticons still followed Megatron to Iron Mountain, where they revealed the next part of their plan and fired cerebro-shells at Megatron and the Seekers. The latter group fell victim to Bombshell, but Megatron managed to grab and crush the shell fired at him, causing Bombshell to cry out in pain. After the Insecticons lost the power of the Nova Power Core, Bombshell lost control of Soundwave and the Seekers, and their shells were ejected. He then used a "special" cerebro-shell to re-assemble Shrapnel, who had been blown to pieces. The Insecticon Syndrome

By order of Soundwave, someone who looked just like Bombshell injected something that worked just like a cerebro-shell into Beachcomber in an effort to make him assassinate Blaster, the inspirational broadcaster for the Autobots. Beachcomber eventually managed to fight it and override the control mechanism, but the effort burned out a large portion of his neo-cortex. Spotlight: Blaster

Many years later, after the true Bombshell was created, he invented actual cerebro-shells. These devices appeared as small representations of Bombshell's insect mode, roughly the size of a Cybertronian's hand, and simply had to be attached to a target to mind-control them. Bombshell's commander, Starscream, was uninterested in using his inventions to control an army of mindless "zombies", but later managed to kill a rebel by throwing a cerebro-shell at him and ordering him to die. Realizing that the shells could be used as weapons, Starscream ordered Bombshell to produce more of them. All His Engines

When Hot Rod attacked the Decepticon base, Bombshell tried to replicate Starscream's trick, but the Autobot blocked the cerebro-shell with a piece of wreckage.

Tasked by Megatron with perfecting combiner technology, Bombshell used cerebro-shells to experiment on Sunstorm, turning him into an example of the perfect combiner component: a mindless drone with no will of his own.

When Dirge found the body, Bombshell planted a cerebro-shell on him to keep him docile, but the device was discovered by Prowl who tracked its signal and confronted the Insecticon, seemingly killing him and breaking the shell's effect on Dirge. Devisive In fact, the cerebro-shell discovered by Prowl had been used to mask an even smaller one, which was able to implant itself into the Autobot thanks to previous damage to his mind, leaving him under Bombshell's direct control. Using this shell, Bombshell had faked his own death and went into hiding, continuing to manipulate political events through Prowl for a long time. Before the Dawn

Notes

• As a kind of easter egg, Dreamwave's cerebro-shells were patterned after Needler, Bombshell's Action Master partner.
• Cerebro-shells are the basis for the movie continuity Insecticons' cerebro-strips.
• The Seacon Coelagon has a very similar power called Coelatelepathy, which allows him to possess others by inserting one of his scales.
