Ghostfreak

Ghostfreak is the Omnitrix's DNA sample of an Ectonurite from the planet Anur Phaetos.

Appearance
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. When using his powers of invisibility and intangibility, the Omnitrix symbol also turns the color of Ghostfreak.

In the original series, Ghostfreak's Omnitrix symbol peeks out of his skin on his lower left chest. He spoke with a faint, whispering voice.

In Alien Force, Ghostfreak looks like Zs'Skayr, except his eye is green and the Omnitrix symbol is on his chest. His voice is considerably deeper, and sounds more like he is gasping.

In Ultimate Alien, Ghostfreak looks like how he looked in the orignal series, but more muscular. His eye is bigger and green. Ghostfreak wears the Ultimatrix symbol on his chest instead of inside.

In the Omniverse comics, 11-year-old Ben's Ghostfeak now has two eyes and a mouth and has chains all over his front side which lead to his neck, waist, and the center/chest. He also has two cuffs on each of his arms. The Omnitrix is located at the center of his chains.

Powers and Abilities
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 (normal form) has enhanced strength, durability, agility, speed, movable eye, invisibility and space survivability.

Zs'Skayr (Ghostfreak's DNA Source) is able to possess the bodies of his enemies and control their movements, allowing him to freely slam them against walls or hit themselves, Ghostfreak has never done this successfully since his only seen attempt failed.

Ghostfreak (true form) has telekinetic abilities seen in Ghost Town, when he fought against Vilgax using only his telekinetic abilities with energy beam projection. His true form also has sharp teeth and claws.

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.

Weaknesses
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.

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.
