Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best
75. King Hydroflax
Appears in: The Husbands of River Song.
The Tenth Doctor said that he hated "funny robots", but even he would've found King Hydroflax amusing. It certainly helps that Greg Davies is a naturally funny man; even when he's playing a contemptible cyborg who eats his enemies (dead or alive) and threatens to use his body as a bomb to destroy an entire solar system.
Talking of Hydroflax's body, this part is voiced equally funnily by Nonso Anozie, especially when it misinterprets the King's survival at all costs order by disintegrating Hydroflax's head.
