Zagbor

The Zagbors were an advanced humanoid race. In 1969, a Zagbor spacecraft landed in London, where they hypnotised the people and made them their slaves. When they found that the Second Doctor had not been hypnotised, they tried to capture him, but he took refuge in the TARDIS. The Zagbors took the TARDIS to their ship and tried to open it with their ray cutter. When the TARDIS failed to dematerialise, the Doctor surrendered to Zagbors, who attempted to hypnotise him. Instead, the Doctor hypnotised them, then freed the people of London. (COMIC: The Zombies)
