James Gunn has clarified that while Man-Bat was considered for Creature Commandos, the character never made it any further.

Toward the end of January, DC Studios co-chair James Gunn answered a question on Threads about other characters he considered for Creature Commandos. "I definitely considered Wolfpack, and, especially, Man-Bat (one of my faves). But I knew I wanted to tell Weasel’s story so it felt like too many rabid and fuzzy characters." He went on to add, "I considered Vincent Velcoro but wanted to choose a “creature” far outside the usual roster from another part of DC - so I went with Dr. Phosphorous instead. I also considered Solomon Grundy, another favorite, but was pretty set on Frankenstein."

Now, switching over to Bluesky, Gunn was asked if we will ever see Man-Bat in the DCU. "Man-Bat wasn’t going to be in [Creature Commandos] he’s merely one of the many characters I considered," He went on to add, "And yes I’d be disappointed if we never see MB in the DCU."

While it's not a definitive answer, it sounds as though the door is still very much open.

While season 1 has wrapped up, the series left it open to adding other characters in season 2. If any of the ones mentioned will make the team remains to be seen as it seems he would want to go in other directions.

Creature Commandos season 1 is currently available for viewing on Max.
