Cobalt bomb
From Tardis Wiki, the free Doctor Who reference

A number of advanced races had access to cobalt bombs, or the technology to create them. These included:
- Qataka (NA: Timewyrm: Genesys)
- Greld (MA: The Empire of Glass)
- Waro (PDA: The Devil Goblins from Neptune)
- Cybermen (NA: Iceberg)
