Xenol
From Tardis Wiki, the free Doctor Who reference
General Xenol was a being in the Second Empire Universe who was involved in the Multiverse Wars and who was written by M. Master. Olivia Kagg Waldermein noted that M. Master's "more humanistic" Xenol was not to be confused with the Black Knight mentioned in Dionus' diaries who was from the Third Universe.

Behind the scenes
The rebellious General Xenol, a Black Dalek, features in Mechmaster's webcomic Second Empire, which is not a valid source on this wiki.
