Quiquaequod

Lord Quiquaeguod was an alternate dimension version of the Eighth Doctor. He was a wizard.

On one occasion, he and his apprentice, Sayde le Fey, entered the Darkling Realms and fought the Darcoul. Quiquaeqoud used his powers to summon fire to burn the Darcoul's wings. The flames accidentally spread onto Sayde's cape. Quiquaeqoud could only watch in terror as his apprentice burned to death. (COMIC: The Glorious Dead)

Behind the scenes
Quiquaeqoud's name comes from TV: The Dæmons, where the Third Doctor calls himself "the great wizard Qui Quae Qoud".
