|Latest appearance||"Princess Cookie"|
Stormo briefly appears in "Princess Cookie," still locked in mental combat with Goliad. He is in the background of Princess Bubblegum while she is considering Finn and Jake's plan to neutralize the hostage situation.
Stormo is a white griffin. Like Goliad, he is a quadruped and has a feline-like body and a third eye in the middle of his forehead. However, unlike Goliad, Stormo has a noticeably birdlike head, complete with a beak. He has a slender white tail with a yellow sphere on the tip. He has a long blond mane that is reminiscent of Finn's hair.
Princess Bubblegum notes that Stormo has the same psychic powers as Goliad, and the two are perfectly matched. This means he is capable of mind control, telekinesis, reanimation, and likely other feats. He also inherited Finn's heroic qualities, and will not hesitate to save people or sacrifice himself to stop villains.
- For all intents and purposes Stormo can technically be considered Princess Bubblegum's and Finn's child.
