10 Actors Who Appeared In Star Trek AND Batman: The Animated Series

7. René Auberjonois - Dr. Robert March

René Auberjonois appeared in two episodes of Batman: The Animated Series as Dr Robert March, though this was far from his only DC or Batman-related role. He had previously appeared (and would later reprise) in the role of DeSaad in Super Friends and Justice League, and he also boasts a live-action appearance in Batman Forever, as Dr Burton. 

He also voiced and sang in Disney's The Little Mermaid before appearing in either Batman: The Animated Series or in Star Trek. He first appeared in the latter as Colonel West, a role that was cut from the theatrical version of Star Trek VI: The Undiscovered Country.

He is, of course, most famous for his grumbling Constable Odo, appearing in Deep Space Nine for its entire run. Though it was this role that would win the hearts of Star Trek fans, it was not his final role in Trek. He guest-starred in the episode Oasis of Star Trek: Enterprise, playing Ezral opposite another future-Trek alum, Annie Wersching.
