Cobalt bomb
From Tardis Wiki, the free Doctor Who reference
A cobalt bomb is an explosive device with greater destructive power than that of a standard nuclear weapon.

- Qataka (NA: Timewyrm: Genesys)
- the Greld (MA: The Empire of Glass)
- the Waro (PDA: The Devil Goblins from Neptune)
- the Cybermen (NA: Iceberg)
- the Klytode (DWAM: The Snag Finders)
