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

– Ben after turning into 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, however his true form is unknown.

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 enslaved Chimera Sui Generi from Ghost Town, but was more muscular. His eye was bigger and green with a black pupil, and the spikes on his elbows were gone. Ghostfreak wore the Ultimatrix symbol on his chest.

In Omniverse, Ghostfreak now has green chains all over his front side which lead to his neck, waist, and center/chest, giving him the appearance of being contained in a straitjacket, but with his arms out freely. 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, Ghostfreak appeared to share the same personality as Zs'Skayr, making himself a dangerous alien to use.[1] This was proven in Alien Force, when Zs'Skayr completely took over Ben when he turned into Ghostfreak.[5]

By Ultimate Alien, however, Ghostfreak has begun to exist as a separate individual whose character was independent from Zs'Skayr's.[6] As of Omniverse, Ghostfreak's connection to Zs'Skayr is no longer an issue, making him safer to use.[3]

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. In the case of Darkstar, he also had access to his powers once he possessed him.[3]

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

Ghostfreak can make himself intangible and invisible as both a powerful defense and infiltrating high-security locations.[7] Ghostfreak can choose to selectively make parts of himself corporeal or slightly corporeal. This extended technique can be used to interact with the world or fight while still intangible. It can also be used in a more deadly way by interacting with someone's internal body parts, such as causing a stroke by attacking Thumbskull's brain.[1]

Ghostfreak is capable of making other objects or people intangible and transparent through physical contact;[3] this feat was first demonstrated by Zs'Skayr.[2]

Ghostfreak can use the tentacles under his second layer of skin as a means of scaring his enemies into submission.[8] These tentacles can grow sharp thorns that can be used as lethal weapons.[9]

Ghostfreak has an eerie, glowing eye[merch 1] that can move around his body, which is especially seen when he wears his outer skin.[10]

Ghostfreak possesses enhanced strength, as shown when he used his tentacles to grab a bus full of people, and can throw one of Vilgax's drones with his hands.[11]

Ghostfreak is immune to Darkstar's energy absorption ability. 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]

Ghostfreak has sharp claws, which can easily tear through Vilgax's Drones.[12]

Ghostfreak can make people feel deathly cold by simply moving right through them.[10]

Ghostfreak can alter his shape and deform like gas by making himself into a grey, somewhat transparent smoke-like wispy form.[10] While in this form, he is immune to being absorbed by Gutrot's species.[DJW 7]

Ghostfreak has enhanced durability, as he was able to withstand a punch from Kraab, which threw him against a wall.[10]

Ghostfreak is able to disrupt electronics by phasing through them, as demonstrated by Zs'Skayr.[13]

Like all Anur System aliens, Ghostfreak is immune to the effects of Corrodium and can see in the dark,[DJW 8] the former of which has been demonstrated by Zs'Skayr.[2]

Due to being alive in a rather unconventional sense, Ghostfreak can survive in the vacuum of space; this feat was also exclusively demonstrated by Zs'Skayr.[2]

Unlike all other Ectonurites, Ghostfreak is immune to sunlight due to some of Ben's DNA being within him.[1]

True Form

As demonstrated by Zs'Skayr, Ghostfreak can completely devour souls.[13]

Although he has never trained himself to do so, he can rotate his skull[DJW 9] much like Zs'Skayr.[13]

Ghostfreak can project powerful energy beams from either the tentacles in his chest and or his hands whenever his skin is peeled back, as demonstrated by Zs'Skayr.[2][5]

Ghostfreak is capable of telekinesis; though he has never formally done so on his own accord, this feat was first demonstrated when Zs'Skayr took over Ben's body.[5]

If 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]


Ghostfreak's intangibility is useless when faced by another being that can go intangible, as it will cancel out their ability to do so.[14]

Certain substances can neutralize Ghostfreak's intangibility and invisibility, such as a special orange liquid used by Kraab.[10] It is possible that Gutrot's species can replicate this liquid in a gaseous form.[DJW 10]

Ghostfreak's intangibility seems to require 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 certain beings Ghostfreak cannot possess. For example, he cannot possess zombies due to them lacking minds of their own.[15] He is also unable to possess the Sentient Ultimate forms[6] or Dagon.[DJW 11]

Like the rest of his kind, Ghostfreak cannot survive on Anur Vladias.[DJW 12]

Ghostfreak can easily be scared by Toepick's species.[DJW 13]

Ghostfreak can be affected by a Nemuina's sleeping dust.[DJW 14]

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



  • 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.

  • Ghostfreak is a living being; the Ectonurite concept of "life" is just very different from most sentient life forms.[DJW 15]
  • Dave Johnson designed Ghostfreak for the Original Series. Looking back on the design, he noted he found the eye quite funny.[DJ 1]
  • "Ben's not here", a line said by Ghostfreak in Ghostfreaked Out, was used in auditions for the role.[AC 1]
  • 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.
  • Ghostfreak's voice has changed over the course of his appearances:
    • In the Original Series, he spoke with a faint and whispery voice.
    • In Alien Force and Ultimate Alien, his voice was considerably deeper and raspy like Zs'Skayr.
    • In Omniverse, his voice has returned to the faint and whispery way it was in the Original Series, albeit it was higher pitched.
    • In And Then There Were None, Bad Ben's Ghostfreak sounded more like Zs'Skayr compared to his main counterpart.
  • When Ghostfreak was taunting Kraab in Hunted, Ben may not have been the one in control.[pop-up 3][10] After he reverted, Ben even stated that it felt "even weirder" than when he is normally Ghostfreak.
  • 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.
  • Ghostfreak replaces Shocksquatch in the intro for Omniverse's Arc 5, specifically in the part where the latter normally appears alongside Toepick, Astrodactyl, and Bullfrag as of Arc 4.
  • Ghostfreak's powers of invisibility, intangibility, and body possession are similar to the DC Comics character, Deadman.
  • 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 second-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.
  • 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 1][DR 2]
  • Ghostfreak is the first alien form that has managed to repress Ben's personality. Eon followed this trend prior to being retconned.[pop-up 4][17]
  • Despite using him at least once to terrorize a city when he was 11,[18][19] Kevin states he never liked Ghostfreak.[20] This was likely due to feeling Zs'Skayr's presence while as Kevin 11.[DR 3]
  • 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.
  • Had he appeared in Omniverse flashbacks, 11-year-old Ghostfreak would have resembled his 16-year-old self but without the chains.[DJW 16]
  • If the Omnitrix times out while Ghostfreak is possessing something, Ben would pop out before becoming solid.[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 secondary skin.[DR 4]
