Young (The Sea Devil)

Miss Young was a companion of the Fourth Doctor for a brief time during his early years on Earth.

Biography
On one occasion, the Doctor pair went to Scotland in Bessie to meet with Professor McBane, an old friend of the Doctor who had summoned him. The friend revealed that a meteor had crash landed in oil rig waters, and he wanted the Doctor's input on the chance of alien hostility. As the group flew over the area in a helicopter, giant tentacles arose from the sea and began attacking a local ship. The Doctor was able to take a sample of the pink substance from the creature back to the laboratory, where he discovered that it was seaweed contaminated from radiation from deep space brought by the meteorite. Furthermore, the mutated seaweed was attracted to sound, so the sound of the oil rig put it in danger.

The Doctor and Miss Young headed out on a boat, using a sound-emitting gadget to attract the mutated seaweed. A tentacle grabed the Doctor, but Miss Young cut it off. They lured the mutation into a shallow bay where it couldn't dive and dropped drums of petrol from the boat. After they were flown out of the area, the petrol was light on fire, killing the beast. Afterwards, the Doctor and Miss Young drove back to the TARDIS for more adventures. (COMIC: The Sea Devil)
