I still feel like me. Maybe I don't have to be scared to use him anymore!

– Ben after using Ghostfreak for the first time in Omniverse.[3]

Ghostfreak is the Omnitrix's DNA sample of an Ectonurite[4][1] from the planet Anur Phaetos in the Anur System.[merch 1]


Ben as Ghostfreak[]

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.

In the Original Series, Ghostfreak's original Omnitrix symbol peeked out of his skin on his lower left chest, and he had a pink eye with a black pupil.

In Alien Force, Ghostfreak looked exactly like Zs'Skayr did in the same series, except his eye was green and the original Omnitrix symbol was on his chest.

In Ultimate Alien, Ghostfreak looked like the Ectonurite designs seen in Ghost Town, except his eye was green. Ghostfreak wore the Ultimatrix symbol on his chest. In the Ultimate Alien opening, the line patterns on his body were different.

In Omniverse, Ghostfreak now has green chains all over his front side which lead to his neck, waist, and center/chest. The spikes on his elbows have returned, his skin is now a greenish-white shading, and he has two cuffs on each of his arms. The Omnitrix symbol is located at the center of his chains. When possessing someone, he has a green glow. His tentacles are now black and purple-striped, and his eye is colored green.

Bad Ben as Bad Ghostfreak[]

Bad Ben's Ghostfreak looks similar to Ben Prime's Ghostfreak in Omniverse, except the green parts of Bad Ben's version's body are colored mint green and his chains are colored blue-green.


During the Original Series, due to secretly hosting the consciousness of Zs'Skayr on top of Ben's, Ghostfreak would often act radically. This was most prominent during fights, as he would go out of his way to scare;[5] intimidate;[6] and use moves that were more cruel and lethal in intent,[1] making himself a dangerous alien to use.

The power of Zs'Skayr's influence over Ghostfreak would get progressively more apparent; meanwhile, Ben would feel more and more uncomfortable whenever he transformed back.[6][5][1] Eventually, Zs'Skayr's consciousness was able to completely overtake Ben's own during at least two instances,[pop-up 2][1] culminating in his and Ghostfreak's escape from the Omnitrix.

Due to the reckless nature of Ghostfreak's reunlocking in Alien Force, it was easy for Zs'Skayr to completely take over Ben's personality again.[7]

By Ultimate Alien, however, Ghostfreak has begun to exist as a separate individual whose character was independent from Zs'Skayr's.[8] As of Omniverse, Ghostfreak's connection to Zs'Skayr is no longer an issue, making him safe to use.[3]

Powers and Abilities[]

But you know what they say- possession is nine-tenths of the law.

– Ghostfreak to Darkstar.[3]

Ghostfreak can make himself intangible and invisible as both a powerful defense and a way of infiltrating high-security locations.[9] As an extended technique, Ghostfreak can choose to selectively make parts of himself corporeal or slightly corporeal to still interact with the world or fight, the most deadly example of which being when Ghostfreak passed into Thumbskull's body and incapacitated him without a chance to fight back.[1] An additional effect of Ghostfreak's intangibility is that he can make those he passes through suddenly feel deathly cold.[6] Ghostfreak is also capable of making other objects or people intangible and transparent through physical contact;[3] first demonstrated by Zs'Skayr.[2] Additionally, Ghostfreak is able to disrupt electronics by phasing through them, as also demonstrated by Zs'Skayr.[10]

Ghostfreak is able to possess the bodies of his enemies and control their movements, to the point where he can cause them to fly around like himself, and can even stop possessing them midair to let them slam into walls.[1][2] He can also access the abilities of other beings that possess superpowers.[3] Additionally, Ghostfreak can completely erase someone's consciousness while possessing them if his willpower is strong enough, as demonstrated by Zs'Skayr.[10]

Ghostfreak can possess Florauna,[pop-up 1][2] Vladats,[DJW 1][11] Transylians,[2] Necrofriggians,[DJW 2] Atrocians, Polymorphs,[DJW 3] Galvanic Mechamorphs, Microchips, Chronosapiens,[DJW 4] Celestialsapiens[DJW 5] and even other Ectonurites.[DJW 6]

Ghostfreak can expose tentacles from his chest, either by drawing back his outermost layer of skin or bursting them through his skin.[12][13] These prehensile tentacles are very useful for grabbing objects[1][14] and/or coiling around people or objects;[13] stabbing;[12] and generally increasing his scare factor.[5]

Ghostfreak is capable of telekinesis, shown off by Zs'Skayr while he was still in the Omnitrix, when he used his telekinesis to make flames erupt from Bunsen burners.[1] Ghostfreak is also capable of telepathy.[merch 2]

Ghostfreak can regenerate lost skin if needed, as demonstrated by Zs'Skayr when he was in control of Ghostfreak's body.[7]

Ghostfreak is capable of flight and levitation, which he can use to soar through the air at high speeds.[15][14]

Ghostfreak has sharp claws, which can easily tear through Vilgax's Mechadroids.[16]

Ghostfreak possesses enhanced strength, as shown when he lifted a large wrestling mat with Acid Breath on top[1] and used his tentacles to grab a bus full of people.[14]

Ghostfreak has enhanced durability, as he was able to withstand a punch from Kraab, which threw him against a wall.[6]

Ghostfreak can survive in the vacuum of space, as demonstrated by Zs'Skayr.[2]

Ghostfreak is immune to having his mana absorbed by energy absorbing opponents, such as Michael Morningstar. This is because Ectonurites do not have mana, as they are not alive in the same conventional way that most other life forms are.[3][DJW 7]

Unlike all other Ectonurites, Ghostfreak is immune to sunlight due to the help of the Omnitrix.[1][note 1]

Ghostfreak's tail is prehensile, as demonstrated by Zs'Skayr when he was in control of Ghostfreak's body.[7]

Ghostfreak has an eerie, glowing eye[merch 1] that can move around through the black lines on his body, which functionally gives him 360-degree vision.[6] Additionally, like all Anur System aliens, Ghostfreak can see in the dark.[DJW 8]

Ghostfreak is able to store small objects under his skin flaps, as demonstrated by Zs'Skayr.[18]

Ghostfreak can alter his shape and deform like gas by making himself into a grey, somewhat transparent smoke-like wispy form.[6][9] While in this form, he is immune to being absorbed by Gutrot's species.[DJW 9]

Although he never trained himself to do so, Ghostfreak may be able convert other species into Ectonurites, where then he is able to manipulate them into doing what he wants.[7][note 2]

True Form[]

Ghostfreak can project powerful energy beams from either his chest and or his hands whenever his skin is peeled back, as demonstrated by Zs'Skayr.[2][7]

In his true form, Ghostfreak's telekinesis is greatly enhanced, being able to even move an entire pillar without effort.[7]

In his true form, while exposed to total darkness, like that of space, Ghostfreak's powers and abilities would be greatly enhanced to their full potential; this feat was also demonstrated with Zs'Skayr.[2]

Although he has never trained himself to do so, he can rotate his skull,[DJW 10] much like Zs'Skayr.[10]


Certain substances can neutralize Ghostfreak's intangibility and invisibility, such as a special orange liquid used by Kraab.[6] It is possible that Gutrot's species can replicate this liquid in a gaseous form.[DJW 11]

Ghostfreak's intangibility requires conscious thought to activate, so opponents will be able to hit him if he is caught off-guard, as seen when he got hit by a punching bag that Thumbskull threw at him while he was distracted.[1]

There are a number of weaknesses that Ghostfreak is vulnerable to if he remains tangible and caught off-guard. For example:

Ghostfreak can be tracked by opponents who can sense heat or use thermographic vision, as demonstrated by Kraab.[6]

There are certain beings Ghostfreak cannot possess. For example, he cannot possess zombies due to them lacking minds of their own.[13] He is also not able to possess Omnitrix transformations,[1] including the Sentient Ultimate forms (when inside the Ultimatrix);[8] nor Dagon.[DJW 12]

Even if Ghostfreak does possess someone, it may be possible for them to reject him out of their body, as shown with Ma Vreedle.[19]

Like the rest of his kind, Ghostfreak cannot survive on Anur Vladias.[DJW 13]

Ghostfreak can be scared by Toepick's species.[DJW 14]

Ghostfreak can be affected by a Nemuina's sleeping dust.[DJW 15]



  • In A New Dawn, 16-year-old Ben as Ghostfreak failed to possess the zombie red coat.

Prior to Ben 10[]

Ben 10[]

  • Ghostfreak first appeared in Permanent Retirement, where he frightened Gwen, escaped Vera's house, drove a golf cart, was about to steal an apple pie before being disgusted by a Limax disguised as a human woman, and then followed another one disguised as Marty.
  • In Hunted, Ghostfreak failed to scare Gwen and defeated Kraab.
  • In Last Laugh, Ghostfreak scared and defeated Zombozo, freeing everyone's happiness in the process.
  • In Kevin 11, Ghostfreak snuck into a game room and played a Sumo Slammers video game.
  • In Secrets, Ghostfreak briefly appeared in the middle of a fight before the malfunctioning Omnitrix made him switch into Grey Matter. Later, Ghostfreak escaped from Vilgax and searched for Gwen and Max before switching into Wildmutt.
    • Also, Ghostfreak appeared as one of the many alien templates used for Vilgax's army in an imaginary sequence.
  • In The Big Tick, Ghostfreak failed to defeat the Great One.
  • In Framed, Gwen mentioned Ghostfreak was used by Kevin to terrorize Barstow, California.
  • At some point prior to Ghostfreaked Out, Ghostfreak snuck into a horror movie, during which Zs'Skayr secretly took control and contacted Viktor with his plans.[pop-up 2][2]
  • In Ghostfreaked Out, Ghostfreak tricked and tortured Wildmutt in a dream. Later, Zs'Skayr took over Ghostfreak and violently battled the Circus Freaks until he reverted.
    • This would remove Ghostfreak from the active playlist, thereby allowing Zs'Skayr to escape the Omnitrix.
  • In Be Afraid of the Dark, Ben regained Ghostfreak (in his true form) by unknowingly scanning Zs'Skayr, though Ben never transforms into Ghostfreak for the remainder of the series out of fear the evil Ectonurite would take over again.

Prior to Alien Force[]

  • At some point in time, Ghostfreak was removed from the Omnitrix.

Alien Force[]

  • In Ghost Town, Ben scanned Zs'Skayr again and transformed into Ghostfreak. When Zs'Skayr quickly regained control, Ghostfreak was able to revert to Ben with the "help" of Vilgax.

  • According to himself in the Original Series, Ben was always creeped out when he was Ghostfreak. Even six years later (especially after the Zs'Skayr incident), he was still afraid to transform into him. When he transforms into Ghostfreak in Mystery, Incorporeal, he states that he feels like himself, suggesting that Ghostfreak now exists independently from Zs'Skayr.
    • As such, in the Original Series, Ghostfreak was the least used out of all the original ten aliens Ben had access to, only appearing in seven episodes and being used a total of eight times.
  • In The Alliance, Ben wanted to use Ghostfreak to try and help an injured Max at the hospital by "melding" with him. This indicates that Ben already knew about Ghostfreak's ability to possess people, even though he never does this onscreen until Ghostfreaked Out.
  • Despite using him at least once to terrorize a city when he was 11,[20][21] Kevin states he never liked Ghostfreak.[22] This was likely due to feeling Zs'Skayr's presence while as Kevin 11.[DR 1]
  • Ghostfreak is one of five aliens to appear in each series of the Classic Continuity; the other four being Cannonbolt, Upchuck, Way Big, and Diamondhead.
    • However, Ghostfreak is the only one of these aliens who has changed his appearance throughout all four series of the Classic Continuity, albeit it was only due to using his true form in Alien Force and outermost-skinned form in Ultimate Alien.
  • Ghostfreak is also one of the only five aliens who escaped from the original Omnitrix; the others being Chromastone, Spidermonkey, Goop, and Way Big.
  • In the intro for the first two seasons of the Original Series, Ghostfreak's eye is red instead of purple.
    • It is also worth noting that after Season 2, when Zs'Skayr successfully escapes the Omnitrix and thus removing Ghostfreak from it, he is replaced with Cannonbolt in the intro for the third and fourth seasons.
  • Ghostfreak is one of two exceptions to the principle that transformations are not full-blown aliens due to retaining Ben's personality, memories, and consciousness; the other being Feedback.[DR 2][DR 3]
  • Ghostfreak is a living being; the Ectonurite concept of "life" is just very different from most sentient life forms.[DJW 7]
  • If the Omnitrix times out while Ghostfreak is possessing something, Ben would pop out before becoming solid.[DJW 16]
  • As of Ultimate Alien, Ben has learned how to retract his outermost layer of skin as Ghostfreak.[DM 2]
  • When Ghostfreak was taunting Kraab in Hunted, Ben may not have been the one in control.[pop-up 4][6] After he reverted, Ben even stated that it felt "even weirder" than when he is normally Ghostfreak.
  • Ghostfreak is the first alien form that has managed to repress Ben's personality. Eon followed this trend prior to being retconned.[pop-up 5][23]
  • Dave Johnson designed Ghostfreak for the Original Series. Looking back on the design, he noted he found the eye quite funny.[DJ 1]
  • Ghostfreak's green-tinted skin in Omniverse was inspired by the coloration of glow-in-the-dark toys.[DJW 17]
  • "Ben's not here", a line said by Ghostfreak in Ghostfreaked Out, was used in auditions for the role.[AC 1]
  • Had he appeared in Omniverse flashbacks, 11-year-old Ghostfreak would have resembled his 16-year-old self but without the chains.[DJW 18]
  • In a promotional image for Cartoon Network and Ayala Mall's Animate Your Life This Halloween, Reboot Ben is seen wearing a Ghostfreak costume.
  • Had Ghostfreak appeared in the reboot, his design would have been similar to his appearance in the Original Series with the Omnitrix symbol peeking out from under his outermost skin.[DR 4]


  1. This page was created on August 11, 2007, by a user named Ghostfreak. This earliest revision made indirect mention of Zs'Skayr's form being "sun-weakened" and without "protective skin". Thus, Ectonurites had been, for the longest time, portrayed on the wiki as only weak to sunlight when without their outermost layer of skin. However, both pop-up trivia and Ben and Zs'Skayr's dialogue in Ghostfreaked Out corroborate that it is explicitly Zs'Skayr's merging with Ben, and benefiting from his DNA, that would have allowed him to "become whole" and surpass his vulnerability to sunlight.[1][pop-up 3][2] It is inferred from this that the Omnitrix is ultimately what keeps Ghostfreak from being hurt by the sun.[17]
  2. Zs'Skayr gained this ability sometime after the Original Series.[DM 1] It is unknown whether Ghostfreak, and by extension, other Ectonurites, can do this naturally.
