|"Unicorns! Now these I know!"|
|— Danny Phantom on unicorns|
In "Boxed Up Fury", the Box Ghost uses Pandora's box against Skulker, only to release a small, stuffed-animal-like unicorn. Skulker angers the Box Ghost, and, channeling off of the latter's emotions, the creature transforms into a giant, beast-like unicorn that chases after Skulker through the Ghost Zone. At one point, it duplicates into multiple versions of itself while chasing Skulker.
After transforming from a small, cute size, the ghost unicorn is a giant, menacing unicorn with dark pink fur, red eyes, and a flaming blue mane and tail. It has a forked tongue, large fangs, and a silver-and-blue horn.
- Intangibility, Invisibility, and Flight: Standard ghost powers.
- Transformation: It transforms itself into a big, powerful, savage, and almost unstoppable unicorn with amazing strength that destroys everything and everyone in his path.
- Ghost Ray: It can shoot blue ghost rays from its horn.
- Duplication: At some point while chasing Skulker, the unicorn can split its body into duplicates that all share the unicorn's ghost powers.
