Sontaran blaster
From Tardis Wiki, the free Doctor Who reference
Sontaran lasers are a form of energy weapon, a recent development of the Sontarans. Sontaran lasers were used to great effect in the Sontaran invasion of Earth in 2009 and proved a great weapon against UNIT. THey fired a red energy burst that could kill a human with a single direct hit without leaving any signs of exterior damage. THese were a somewhat new weapon as in the former Doctor Who series they were only ever known to use their batons as weapons. Despite being known as "lasers", their bolts travel slower than light.
