Disruptor Dalek
From Tardis Wiki, the free Doctor Who reference
The Disruptor Dalek was a Dalek variation who fought in the Time War.
Leela described it as a big, blue and grey Dalek, and compared its top with a glass bowl.
During the Battle of the Pillars of Consequence, the Disruptor Dalek faced Leela and shot her. This caused Leela to be displaced from time and space. (AUDIO: The Lady of Obsidian)
