Blockbuster
- Voice Actor: James Arnold Taylor (as Mark Desmond), Kevin Michael Richardson (as Blockbuster)
Desmond is a devious and evil child genius who can turn into that same villain by drinking a formula from S.T.A.R. Labs. He appears in the teaser of "Death Race to Oblivion" where Batman confronts evil child genius Desmond (who Batman has been keeping an eye on since he stole some chemicals from S.T.A.R. Labs) at a museum with a plot to steal a diamond called the Star of Bionya. The crowd objects to Batman grabbing Desmond until the boy drinks the serum that transforms him into Blockbuster. As Blockbuster, he subdues Batman. When Billy Batson steps forth, Blockbuster grabs him. When Blockbuster asks Billy if he has any last words, he quotes "Shazam" and transforms into Captain Marvel who manages to defeat Blockbuster.
