Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best
211. Gathering Coil
Appears in: The Woman Who Fell to Earth, Revolution of the Daleks.
A half organic, half machine entity which was deployed by Tzim-Sha to locate and hunt down a human trophy (Karl the crane operator) and return home with it victorious. Had Toothy Tim succeeded, he would've ascended to leader of his warrior race, the Stenza.
The massive electrically-charged coil itself is visually impressive, highlighting the cinematic VFX provided by DNEG overall throughout the Whittaker/Chibnall era. One also makes a blink and you'll miss it cameo in 2021's New Year's Day special as one of the incarcerated aliens in the Judoon prison.
