Energy blaster
From Tardis Wiki, the free Doctor Who reference
The Energy blasters were created by The Preachers on Pete's World to kill the Cybermen. They could easily blow off the head of a Cyberman.
The Doctor enhanced some blasters to penetrate the heat shields and Polycarbide of a Dalek. The blasters had temporarily disabled the Cult of Skaro's weapons. (DW: Doomsday)
