Ghostfreak is a ghost-like alien, with claw like hands. He had grey skin with black lines running all over him. This skin is removable, which will reveal Ghostfreak's tentacles or his true form.
Powers and AbilitiesEdit
Ghostfreak's powers are composed by several aspects from traditional ghosts of myths and lores, such as hovering and phasing through solid matter, making his intangibility a powerful defense.
Ghostfreak can become invisible.
Zs'Skayr is able to possess the bodies of his enemies and control their movements, allowing him to freely slam them against walls or hit themselves, and as seen in Mystery Incorporeal, can also use their abilities, as shown when he possessed Michael Morningstar and used his abilities to retrieve Gwen.
Ghostfreak has telekinetic abilities seen in Ghost Town, when he fought against Vilgax using only his telekinetic abilities with some beams of blue energy.
Ghostfreak seems to use his tentacles under his protective skin as a means of scaring his enemies into submission, though the real purposes of these tentacles currently remains unclear, though in Omniverse, his tentacles were shown to be strong enough to lift a bus.
As seen in Night of the Monsters, Ghostfreak can also absorb Hueco Mundo's spiritual particles and grow stronger.
Much like other intangible beings, certain substances can neutralize Ghostfreak's intangibility and his invisibility, as seen in Hunted, when Kraab neutralized Ghostfreak's intangibility and invisibility.
Ghostfreak's second skin removes many of his powers.
Ghostfreak can be frozen.
In the original series, Ghostfreak's DNA allowed him to regain his memories and personality, recreating Zs'Skayr, who took over Ben and freed himself after the Omnitrix timed out.
