"Quacula," a vampire duck (pre-dating Cosgrove-Hall's "Count Duckula" by two years, first appearing on Danger Mouse),

The New Adventures of Mighty Mouse and Heckle & Jeckle is an updated version of Mighty Mouse and Heckle & Jeckle cartoons from the 1940s. The television series was produced by Filmation, and aired from 1979 to 1981 on CBS with over 32 episodes produced. It is not to be confused with Ralph Bakshi's Mighty Mouse: The New Adventures.
The Mighty Mouse episodes were atypical, except the violence inherent in the original theatrical cartoons was absent. Heckle & Jeckle cartoons here were pretty non-descript. There were two Mighty Mouse cartoons and two Heckle and Jeckle cartoons. Added to the mix were "Quacula," a vampire duck (pre-dating Cosgrove-Hall's "Count Duckula" by two years, first appearing on Danger Mouse), and "The Great Space Chase," a 16-part serial which was essentially a Star Wars/Flash Gordon spoof. Special features included "Mighty Mouse Environmental Bulletins" and "Homonyms" with Heckle and Jeckle dabbling in sound-alike wordplay.
