Gauntlet of Rassilon
From Tardis Wiki, the free Doctor Who reference
Omega's Gauntlet was a weapon used by Lord President of the Time Lords, Rassilon.
History
Rassilon used the glove to disintegrate a Time Lady when she told him it might be better that the Time Lords died. Along with other Time Lords, Rassilon escaped the Time Lock and travelled to Earth. He used the gauntlet to destroy the Saxon Master facial template set upon the humans. He then also attempted to kill both the Master and the Tenth Doctor, but failed to kill either.
