Not in the same sense as evil geniuses, but similar villains-often without a initial physical form-in WHO's history who have the ability to posess a person or multiple persons, and usually have some hench-monster to do their bidding. Examples:
The Animus-From the Hartnell "Web Planet". Largely used the Zarbi. Physical form resembled a giant fungus.
The Great Intelligence-Controlled the Yeti and used host bodies. Seen in "The Abominable Snowmen" "Web of Fear" and the spin-off video "Downtime". A solo Yeti robot appears in "The Five Doctors" but it's unclear whether it was controlled by the GI.
The Nestene Consciousness-The only classic series intelligence to appear in the new-and right away, too. Controls the Autons and other plastics. Usually appears as a giant octopus like monster in it's physical form, but also as a giant smelting pit in "Rose". Appears in Spearhead From Space, Terror of the Autons and Rose, as well as a good chunk of spin-off material. It is strongly implied in "Rose" that the Autons were involved in the time war, and lost their home planet (Called Polymos in WHO EU)
Sutekh-Not sure if he really counts, since he only controls Scarman and (briefly) The Doctor in Pyramid Of Mars. Plus he has a pretty solid physical form.
Fenric-Perhaps the most methodical of the intelligences, Fenric's plan is not really invasion like the others, but a carefully arranged 'game' of genetic and timeline manipulation. Uses the vampiric haemavores and his unwitting 'wolves' to bring out his plans. Stays in an inamite form in a bottle until unleashed by the Ultima machine. The only known of the intelligences to really have been 'killed' as he hasn't really made any other appearences in spin-offs since. From "The Curse of Fenric".
The Beast- From Impossible Planet and Satan Pit. Similar in powers, attitude and appearence to the classic image of the devil/Satan/Adversary, but otherwise very similar to Fenric (He's even chained similarly) and other intelligences. Uses Toby and the Ood.
