Imp is a little creature of the Horde and apparently is Hordak's pet. He appears to be skilled in stealth and spying, mostly on fellow Horde members. He has the ability to record and repeat what other people say. Lord Hordak uses this often as to his advantage.
Imp is subservient to Hordak but also resists and mocks him as well. At one point, when Hordak is raging, Imp pulls Entrapta away from his master, showing that Imp has empathy and may have befriended Entrapta.
Imp looks like a mixture of a toddler and a bat with teal-gray wings and hair, yellow eyes and a teal skin. He has pale red fangs, long elf-like ears and a long devil-like tail. He looks quite similar to the failed clone experiments of Hordak, hinting that he may be a failed clone himself. His design is similar to a gargoyle.
