Seismic-shock warhead

Considered one of the most dangerous Decepticon weapons ever created, according to Bumblebee a seismic-shock warhead would "hammer to a planet's core" before detonating and "cracking the planet in half".

Season 3
Flamesnort was assigned to Earth by the Decepticons to guard a seismic-shock warhead hidden within an isle offshore of England. When Bumblebee and Fixit arrived on the island, his attempts to fight them were hampered by his extreme old age and Energon deprivation, and, faced with Bumblebee's tale of an Autobot invasion fleet being two days away, chose to execute "Plan Omega" - the detonation of the warhead, to deny the island (and the planet) to the evil Autobots. The two Autobots actually present arrived in his base just as the warhead powered up, but Bumblebee was able to distract Flamesnort from his control console long enough for Fixit to remove the weapon's ignition key before the warhead could detonate and destroy Earth.
