In an interview with Rotten Tomatoes, Creature Commandos creator James Gunn and director Dean Lorey spoke about Batman’s inclusion in the latest episode. Gunn mentioned that the first edit of the episode featured more of Batman,

"He already exists in this universe, just like when we come to the Superman movie and we see that Superman already exists, he's already known by the people in Metropolis," Gunn told Rotten Tomatoes. "We don’t need to hear the origin story again. That’s just a way to introduce that Batman is a part of this universe."

Batman’s cameo in Creature Commandos' sixth episode was originally more detailed than shown and James Gunn wasn’t ready for such commitment.
