Earthshock bomb
From Tardis Wiki, the free Doctor Who reference
Earthshock bombs were a type of highly destructive explosive.
After being altered by the Quantum Archangel, the Master's TARDIS was armed with Earthshock bombs. However, he noted that seeding the time vortex with the bombs would be nothing more "than an irritation" to the Divine Host of the Chronovores. (PROSE: The Quantum Archangel)
In 6211, a Sontaran stealth raid destroyed Tersurus with an earthshock bomb which they had obtained from the Cybermen. (PROSE: The Crystal Bucephalus)
