Scorby

Scorby was a mercenary in the employ of Harrison Chase.

Biography
On Chase's orders, Scorby and Arnold Keeler travelled to a scientific base in Antarctica, where he stole a Krynoid pod discovered there, destroyed the base with a bomb and brought the pod to England. Scorby took the Doctor and Sarah Jane Smith prisoner when they arrived at Chase's mansion. They escaped and Scorby attempted to recapture them. He caught the Doctor and planned to put him through Chase's compost machine. Sarah Jane rescued him.

He later turned against Chase after seeing how dangerous the Krynoid was. Disbelieving in the Doctor's ability to deal with the problem, he tried to flee, but was drowned by plants controlled by the Krynoid. (DW: The Seeds of Doom)
