Ghostfreak

Ghostfreak is the Omnitrix's DNA sample of an Ectonurite from the planets Anur Phaetos and Anur Transyl in the Anur System.

Appearance
Ghostfreak is a phantom/ghost-like alien, with claw like hands. He has grey skin with black lines running all over him. This skin is removable, which will reveal Ghostfreak's tentacles and his true form.

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 the Ectonourites from Ghost Town, but is more muscular. His eye is bigger and green, and the spikes on his elbows are gone. Ghostfreak wears the Ultimatrix symbol on his chest instead of inside.

In Omniverse, 16-year old Ghostfeak appears to now have green chains all over his front side which lead to his neck, waist, and center/chest. The spikes on his elbows have returned and his skin is now a greenish white. He also has two cuffs on each of his arms. The Omnitrix symbol is located at the center of his chains. His voice has returned to the faint and whispering kind.

11-year old Ghostfreak in Omniverse is similar, but instead he has fluorescent skin and sliver chains.

Despite Zs'Skayr having his skull turned right-side-up in Omniverse, Ghostfreak's skull remains upside-down.

Powers and Abilities
Ghostfreak's powers are composed of several aspects from traditional ghosts of myths and lores, such as hovering and phasing through solid matter, making his intangibility a powerful defense as well as a means of infiltrating a high-security location.

Ghostfreak has enhanced strength, durability, agility, speed, movable eye, invisibility and space survivability. Ghostfreak is able to possess the bodies of his enemies and control their movements, allowing him to freely slam them against walls or hit themselves. He can also access the abilities of other superpowerd beings, as in the case of Darkstar, he also has access to his powers once he possess him.

Ghostfreak's true form has telekinetic abilities, as 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, as well as an inverted skull.

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.

Ghostfreak is immune to Darkstar's energy absorption ability, as he is a ghost-like alien and thus has no life energy to absorb.

Ghostfreak can rotate his skull, which explains why he has his skull upisde-down unlike right-side up like Zs' Skayr.

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.

As shown in the original series, Ghostfreak's DNA is linked to the conscience, memories, and personality of Zs'Skayr, who took over Ben and freed himself after the Omnitrix timed out, making Ghostfreak a dangerous alien to use. Ghostfreak now exists independently from Zs'Skayr, complete with Ben's personality so this is no longer an issue.

His intangibility is useless when faced by another species that can go intangible. He can also be frozen by Necrofriggians.

Trivia

 * According to Ben in the original series, he was always creeped out when he was Ghostfreak and still is 6 years later (especially after the Zs'Skayr incident). But when he transforms into Ghostfreak in Mystery, Incorporeal, he states that he feels like himself, suggesting that he is no longer in danger of being taken over by Zs'Skayr.
 * Ghostfreak makes a small cameo in the game FusionFall, inside the Dizzy World Infected Zone.
 * Ghostfreak is the only alien to have different designs in all 4 series.
 * He replaces Shocksquatch in the intro for Omniverse's Arc 5 (the part with Toepick, Astrodactyl, and Bullfrag)
 * In Mystery, Incorporeal, it is revealed that Ghostfreak, and the other Ectonurites don't have mana in them (as mana is life energy, and Ectonurites are not alive in the same way that most sapient lifeforms are).
 * Ghostfreak was used in all 4 series of Ben 10, as well as Diamondhead, Cannonbolt, Upchuck, and Way Big.
 * Ghostfreak's chains seem to be a reference to Jacob Marley from Charles Dickens' A Christmas Carol; a ghost who was bound in chains. Derrick J. Wyatt stated that the chains were a reference to ghosts in general, perhaps nodding to the common depiction of phantoms as being chained.
