Fenris makes an appearance in Corpse Justice (fake) TV series!
In CJ-verse, Fenris' story is slightly different from original DA2. We first meet Fenris as the currently employed butler to Tevinter magister Danarius. During the course of the series, Hawke and the Warden duo confront Danarius and get him arrested under the Warden's Blight Security Act, leaving Fenris very much unemployed and without direction.
Fenris' weapon of choice is a shotgun.
