Having previously stolen a blue crystal from the planet Metebelis 3 for study, the Doctor discovers that a race of mutated giant spiders have taken over and are seeking the return of their crystal.

However, the Third Doctor's eventual regeneration was definitively alien in nature. and taking down baddies with his Venusian aikido. Jon Pertwee's Third Doctor was the most human version yet, driving a jaunty car, joining U.N.I.T.
