Paradox eater
From Tardis Wiki, the free Doctor Who reference
Paradox eaters or paradox feeders were creatures attracted by paradoxes that fed on time, such as the Chronovores and Reapers.
Missy described the Gramoryans as being more "paradox collectors" as they removed historical figures from time to preserve them. (AUDIO: Divorced, Beheaded, Regenerated)
