This is a character LoRA for Mer-Man from the 1983 Filmation Cartoon series He-Man and the Masters of the Universe. He gets more monstrous in later iterations, but I think he's kind of cute in his original 80s design.

You may want to avoid using furry-specific checkpoints, as they really like to give him a mammalian nose. He doesn't even have any nostrils in the show.
Anima and Illustrious models are available. Make sure you grab the right one.
