Hades (Disney's Hercules) as Varys (Game of Thrones)
Varys was difficult and I debated between Jafar and Hades. Hades was sassier as is Varys in the show. They are powerful members of their worlds with influence. Hades, as the god of the Underworld, operates a huge network, necessary for the continuity of the world. He has his minions to provide him with information (however they are pretty unreliable). Hades does look dreadful in pastels though.
