Zs'Skayr (pronounced "Zuh Scare"), also known as Ghostfreak, was the Ectonurite High Ecto-Lord of Anur Phaetos and Anur Transyl in the Anur System. He was originally stuck in the form of Ghostfreak, as a separate personality that would influence Ghostfreak's actions. Over time, he managed to gain enough control over the form that he could escape from the Omnitrix, becoming one of Ben Tennyson's most dangerous enemies. Ghostfreak is the Omnitrix's DNA sample of an Ectonurite from the planet Anur Phaetos in the Anur System.
