Ghostfreak is the Omnitrix's DNA sample of an Ectonurite from the planet Anur Phaetos in the Anur System.
Ghostfreak is a phantom/ghost-like alien with a gaseous appearance and claw-like hands, and grey skin with black lines running all over him. His skin is removable with black and white striped tentacles underneath it, and if his skin gets ripped off, his true form will unveil. The Omnitrix symbol peeks out of his skin on his lower left chest and he has a pink eye with a black pupil.
He has a hoodie to protect his face, which protects his actual skull.
Powers and Abilities
Ghostfreak's powers are composed of several aspects of traditional ghosts from myths and lore such as flight, levitation, phasing through solid matter, intangibility, invisibility, and body possession.
Ghostfreak is able to possess the bodies of his enemies and control their movements to the point where he can cause them to fly like himself, allowing him to freely slam them against walls or hit themselves. He can also access the abilities of other beings that possess superpowers. Ghostfreak can make himself intangible and invisible as both a powerful defense and infiltrating high-security locations. He is also capable of making other objects or people intangible and transparent through physical contact.
Ghostfreak can use the tentacles under his protective skin as a means of scaring his enemies into submission. These tentacles can grow sharp thorns that can be used as lethal weapons. Ghostfreak has a movable eye, which is especially seen when he wears his outer skin. Although his outer skin protects him from burning in the sunlight, his tentacles appear to be resistant towards sunlight. Ghostfreak possesses enhanced strength, as shown when Ben used his tentacles to grab a bus full of people when he was 16.
Ghostfreak can make people feel deathly cold by simply moving right through them. Ghostfreak can alter his shape and deform like gas by making himself into a grey, somewhat transparent smoke-like wispy form.
Ghostfreak's intangibility is useless when faced by another being that can go intangible, as it will cancel out their ability to do so. Certain substances can also neutralize his intangibility and invisibility. Ghostfreak's second skin inhibits many of his powers, but removing it will make him vulnerable to sunlight.
Although he is able to fly, he is not very fast in the air, and therefore must rely on his intangibility and invisibility to evade attacks. Ghostfreak's intangibility seems to require conscious thought to activate, so opponents will be able to hit him if he is caught off guard.
There are certain beings Ghostfreak cannot possess. For example, he cannot possess zombies due to them lacking minds of their own. He is also unable to possess the Sentient Ultimate forms, though the reason why remains unclear. If he remains tangible long enough, Ghostfreak can be controlled and hypnotized by Vladats via their Corrupturas, as demonstrated by many Ectonurite residents of Anur Transyl, and magic can harm him.
