Barky Marky (voiced by Frank Welker) is a young, brown and tan male dog. He is based on the Looney Tunes character Marc Antony. Barky Marky is portrayed as a typical canine who loves to play fetch as well as various other sports and activities. Even though Barky starred in his very own short entitled Go Fetch with Elmyra Duff, as well as making many cameo appearances on other episodes, appearing in the special Tiny Toon Adventures: Spring Break Special and the movie Tiny Toon Adventures: How I Spent My Vacation, Barky Marky was still referenced and mocked for his lack of appearances on the Saturday Night Live spoof Weekday Afternoon Live. When Buster Bunny is reading the news out loud from the viewers complaining about him not being in enough episodes, Babs Bunny, posing as a Tiny Toons casting director, asks "Who's Barky Marky?"
