After their most recent plan has been discovered, Lex Luthor asks how this is possible, causing Grundy to stand and awkwardly admit that he "kinda dropped the ball on that one". In the South Park episode "Krazy Kripples", Grundy makes a cameo appearance as a member of a parody of the Legion of Doom, led by Christopher Reeve. In the StarKid Productions show Holy Musical B@man!, Grundy is mentioned to be the target of a battle that Superman attempts, and fails, to coordinate with Batman, Green Lantern, and Wonder Woman.
