Merlin the Wise

Merlin the Wise, a manipulative and seemingly sinister figure, nevertheless helped the Doctor on a number of occasions.

Biography
The Fourth Doctor first met Merlin in the distant future of Earth. Merlin had appeared from another time period to help the Neutron Knights against their enemy Catavolcus. Merlin had summoned the Doctor himself to help. (DWM: The Neutron Knights)

They next met in the Matrix on Gallifrey where Merlin had joined a council of High Evolutionaries, including Rassilon, founder of the Time Lords, to discuss the danger posed to the universe by the "demon" Melanicus. The Doctor did not entirely trust Merlin but agreed to his aid. Merlin had originally banished Melanicus from the universe, though, obviously he had not managed to make it permanent. (DWM: The Tides of Time)

He was later replaced among the Evolutionaries, under unknown circumstances, by a member of the Order of the Black Sun. (DWM: The Final Chapter)

Behind the scenes

 * This Merlin has a link to the Marvel UK universe (and, more remotely, to the Marvel Universe generally). He appears in a cameo in the Marvel UK comic book Captain Britain as the Marvel Universe Merlin (in another form) shows off some of the other forms and personalities he has, at times, assumed. In the later Captain Britain and MI13, writer Paul Cornell explicitly had them as the same Merlin and also made reference to the High Evolutionaries.
 * Merlin also appeared (though not actually onscreen) in the Doctor Who Universe in the Seventh Doctor television story Battlefield the form of a future incarnation of the Doctor, who was, in One Fateful Knight by Peter David in Short Trips: The Quality of Leadership, revealed as another renegade Time Lord altogether.
