in his lightside Filmlin is a film reel-like Yo-kai creature with arms and legs and feet. He has a small blue flame on his head, a small mouth and a piece of film tape that acts as a tail.

His hands become film projectors, with more film reel attached to the top, and, instead of feet, he moves around on a film reel-like wheel. His tongue resembles a claw. He can shoot a beam from his tongue to make the victim experience their worst fear.
Filmlin debuted in SS020. Filmlin was once a film stock featuring a horror movie created by a famous film director who decided to try his skills at producing a horror film; however, the film itself was poorly received by the audience for being extremely scary. Enraged, the director discarded the film stock, which was picked by his wife, and due to a sorrow tear shed by her, Filmlin came into being. He then used his powers to hypnotize people who went to a certain movie theatre, including Natsume, so that people would watch the movie he produced.

Filmlin is a portmanteau of Film and Gremlin.
