In the film, the Nemean Lion appeared in the "Zero to Hero" song segment, where he was sent by Hades to kill Hercules, however Hercules easily defeated him with a swift punch and a kick to the rear end thus increasing Hercules' fame.
He also appeared in the animated series, where it is revealed that he also fought a young Hercules but believed that Hercules' friend Icarus was the one who defeated him. In the episode, after having defeated all of Nemean's warriors, he grew bored and came to Athens, hoping to find some half-worthy heroes to fight him.

- In Once Upon a Time, the Nemean Lion doesn't appear. However, the creature was mentioned by Hercules when telling his adventures to a teenage Snow White. Also, one of his medals represents this creature.
