Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best

Appear in: Gridlock.

There's being stuck in traffic on the M25, and then, there's taking 12 years to travel only five miles on New New York's motorway.

Unless you stocked up on Happy and Mellow mood drugs, the only saving grace for the travellers was to have at least three passengers in order to gain access to the fast lane, which was located on the lowest level of the motorway. But instead of enjoying outrageous speeds of 30mph, they're greeted by the sinister snapping of the crab-like Macra, who fed off them (and the fumes from the countless cars above).

Like most monsters, the Macra's scare factor is more effective when they're unseen. The shots of the claustrophobic car cabins combined with the sounds of echoey growling will make you want to slap on a Forget and Sleep patch at the same time!
