James Gunn has discussed the other characters he considered for Creature Commandos before the team he settled on for the series.

Gunn was asked on Threads, "Really enjoyed Creature Commandos. Like with The Suicide Squad, did you go through a number of different characters for the team before going with the ones that you chose? And which characters did you consider for the team early on?"

He replied, "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."

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.
