Quiquaequod

Lord Quiquaequod 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. Quiquaequod used his powers to summon fire to burn the Darcoul's wings. The flames accidentally spread onto Sayde's cape. Quiquaequod could only watch in terror as his apprentice burned to death. (COMIC: The Glorious Dead)

Behind the scenes
Quiquaequod's name comes from the television story The Dæmons, where the Third Doctor calls himself "the great wizard Qui Quae Quod".
