Wardog

Wardog was a dimension-travelling parahuman mercenary who led the Special Executive. He was witty, egocentric, and chauvinistic, though he had some form of morality. While humanoid, he had many canine facial features and was covered in hair.

In the early days of the Time Lords, he and the Executive were hired to retrieve the criminal Fenris. Alongside Time Lady Rema-Du, he entered the Zone of No Return and was forced to splinter himself from one end of time to the other to retrieve Fenris. Unfortunately for him, the assassin's employers - the Order of the Black Sun - attacked soon after and blew off Wardog's left arm. (COMIC: 4-D War) Wardog went on to get a robotic arm.

Ten years later, he and other Executive members escorted Rema-Du to a trade negotiation involving the Sontarans and the Order (who, in their timeline, had not yet attacked Gallifrey). When the Sontarans brainwashed Executive member Millenium into becoming an assassin, Wardog killed her to protect the Black Sun Elder. It was too late though, and the Elder died; this was perceived by the Order as the first strike of their time war. (COMIC: Black Sun Rising)

Invalid appearances
In the Walking in Eternity short story Executive Action Wardog appears alongside other members of the Special Executive including Cobweb, Fascination and Zeitgeist. It is explained that the Special Executive are Parahumans, early Loom-born experiments ordered by Rassilon, who are embued with time energies which give them strange abilities. The prototypes were rejected and thus became known as 'The Bastards of Rassilon', although they continue to be used by the High Council to do the Time Lord's dirty work. During a civil war on Gallifrey between the Loom-born and womb-born Gallifreyans, the Special Executive departed Gallifrey leaving the two sides to battle it out.

In Daniel O'Mahony's A Rag and a Bone, published in the fanzine Myth Makers Presents: Essentials in 2003, Sabbath is accompanied by a "dog-faced parahuman" who fought in Gallifrey's First Time War.
