Zs'Skayr(pronounced Zuh Scare) also known as "Ghostfreak", is a villian and was the High Econurite High Ecto-Lord of Anur-Phaetos. He was, in the Original Series stuck in the Omnitrix as Ghostfreak, but after sometimehe manged to gain control of Ghostfreak and escape from the Omnitrix. He is one of Ben Tennyson's most dangerous enemies.
Before the Original Series or before Ben go the Prototype Omnitrix, the original Zs'Skayr was once the High Ecto-Lord of Anur Phaetos. He had learned about the Omnitrix when one of Vilgax's data probes crashed landed on Anur Phaetos and he read all of its data files. Not long after, he had met up with Myaxx when she was scouting the planet for DNA samples and he aided her in aquiring samples from the nearby planet of Flors Verdance, however, unbeknownst to Myaxx, He, Zs'Skayr had possessed one of the Floraunas, the one that was eing sampled, thus making Myaxx get a Ectonurite-Florauna hybrid DNA Sample. For a couple of years Zs'Skayr's personality had been laying dormant within the Omnitrix DNA Database, as Ectonurites' consciousnesses exist even in a single strand of DNA.

- Zs'Skayr's name is a corruption of the word "scary".
- In both the original series and Ben 10: Alien Force no one called him Zs'Skayr - they only called him Ghostfreak.
- In Vilgax Attacks, Zs'Skayr implies that he is undead ("Alive? Interesting word choice.", "Ben 10, as I live and breathe... not!"). However, Derrick confirmed that Zs'Skayr is alive. But the Ectonurite concept of "life" is just very different from most sentient life forms.
- Zs'Skayr can take over the bodies of others, and whenever he takes on their bodies, he also changes the appearance of the victim's eyes, just like Jericho in the Teen Titans episode "Titans Together."
- Derrick has confirmed that he's going to turn Zs'Skayr's skull right side up.
- Zs'Skayr's name was created by Tramm Wigzell.
