of veterans from the golden age of WB cartoons, including writers John Dunn and Dave Detiege. By 1986, Freleng had departed, and Hal Geer also stepped down the following year. Geer was briefly replaced by Steven S. Greene, who in turn was replaced by Freleng's former secretary Kathleen Helppie-Shipley, who would spearhead a major revival of the Looney Tunes brand in the years that followed. The studio continued production on special projects starring the Looney Tunes characters, sporadically producing new Looney Tunes/Merrie Melodies shorts for theaters such as The Duxorcist (1987), Night of the Living Duck (1988), Box-Office Bunny (1990), and Carrotblanca (1995). Many of these shorts, as well as the new footage in the compilation film Daffy Duck's Quackbusters (which includes The Duxorcist), were directed by Greg Ford and Terry Lennon, as well as Darrell Van Citters. 1986–1996: Moving into television animation Beginning in 1986, Warner Bros. moved into regular television animation production. Warners' television division was established by WB Animation President Jean MacCurdy, who brought in producer Tom Ruegger and much of his staff from Hanna-Barbera Productions' A Pup Named Scooby-Doo series (1988–1991).

Darrell Van Citters, who used to work at Disney, would work at Warner Bros. on the newer Bugs Bunny shorts, before leaving to form Renegade Animation in 1992. The first Warner Bros. original animated TV series Tiny Toon Adventures (1990–1995) was produced in conjunction with Amblin Entertainment, and featured young cartoon characters based upon specific Looney Tunes stars, and was a success. Later Amblin/Warner Bros. television shows, including Animaniacs (1993–1998), its spin-off Pinky and the Brain (1995–1998), and Freakazoid! (1995–1997) followed in continuing the Looney Tunes tradition of cartoon humor. Warner Bros. Animation also began developing shows based upon comic book characters owned by sister company DC Comics. These programs, including Batman: The Animated Series (1992–1995), Superman: The Animated Series (1996–2000), The New Batman Adventures (1997–1999), Batman Beyond (1999–2001), and Justice League/Justice League Unlimited (2001–2006) proved popular among both children and adults. These shows were part of the DC animated universe. A Batman spin-off feature, Mask of the Phantasm, was produced in 1993 and bumped up to theatrical release. The film was near universally-well received by critics but performed poorly at the box-office, though it eventually became
