The Omnitrix, a device to allow the wearer to literally walk in the shoes of other alien races, to bring a closer unity in the universe.

Azmuth to Ben.[1]

The Omnitrix is a watch-like device that attached to Ben Tennyson's wrist and is the device that the series revolves around.


Season 1

The Omnitrix looks like a very big wristwatch, primarily black and grey in color, with a grey dial in the middle (like a watch face) which has a green hourglass shape. When Ben selects his aliens, it shows the alien's silhouette.

In Omni-Tricked: Part 3, Phil put on a blue device on the outer side of the Omnitrix. It was supposed to control the temporary malfunction on switching from alien to alien.

Season 2

The Omnitrix was upgraded by Ben using Upgrade in Omni-Tricked: Part 4. The white chords and dial were silver and green. The four buttons on the faceplate were replaced with grey squares. There was an additional band of dark grey running around the center of the Omnitrix, the activation button was on this strip.

Season 3

The Omnitrix got rebooted in Innervasion Part 5: High Override. The rim of the dial was white, the squares on the last upgrade were replaced by green arrows, and the area behind the hourglass and the wristband both became grey. The outer band was black with green arrows, and the sides of the dial and the ends of the wristband were silver. The top of the grey wristband had a green hourglass underneath the dial, and the top of the dial was black. Unlike the Omnitrix's last two versions, the third version did not have its tube-like circuitry.

The Omnitrix in Crossover Nexus looks exactly the same as season 3 but is adapted to the artstyle of O.K K.O Let's Be Heroes!.

The Omnitrix in And Xingo Was His Name-O looks the same but looks more cartoonish.

Season 4 and 5

As of Summer Breakers, the latest upgrade colors the entire device almost completely grey, with the black ends and the arrows on the dial being absent. The hourglass coloring now remains 2-tone grey, and white support tubes surronded the dial.

The Omnitrix in Xingo's World looks exactly the same as season 4 but looks more cartoonish.

Alternate Dimensions

In Alien X-Tinction, the Omnitrix in Dimension 12041.5 looks exactly the same as Season 4 except the white tubes are facing the left side and has a black square.

The Original Series Dimension's Omnitrix looks the same as its Main Timeline counterpart's first design.

The Alien Force Dimension's Omnitrix resembles a slimmer and sleeker watch-like shape, now with a green wristband, and the face of the dial becoming black and green. The inside of the hourglass symbol glowed in different colours during certain moments; these colours signify the mode that the Omnitrix was presently in. When Alien Force Ben is selecting his aliens it shows the alien's hologram standing on the core rather than the alien's silhouette.

The Omniverse Dimension's Omnitrix resembles a digital wristwatch. Its faceplate is now square instead of round and has a white, green, and black color scheme. The faceplate is black with two green stripes forming an outline for the hourglass of the intergalactic peace symbol. When the faceplate is slid back, the Omnitrix's core is revealed.

The Omnitrix of Maximillian's Dimension looks exactly like the Omniverse Dimension's except the inside of the Omnitrix is green and the faceplate can become red when it times out. The vents are also absent from this Omnitrix.

Gwen 10's Omnitrix looks exactly the same as Ben's Omnitrix's Season 1 design except the button on the body and the circles on the dial is absent.

Alternate Timelines

Omnitrices from aborted timelines from episode Ben Again and Again looks exactly same as Season 1 version.


The Omnitrix was created by Azmuth, and assisted by a brilliant Chimera Sui Generis named Vilgax. The device was made to allow the user to walk in the shoes of other alien races, and bring closer unity in the universe.

Known Users

User Put On Removal
Vilgax Prior to the events of the series, Vilgax stole the Omnitrix from Azmuth's lab, and used it to bring the universe together under his rule. Azmuth removed the Omnitrix from Vilgax after trapping half of his DNA inside.
Ben Tennyson Prior to the beginning of the series, Ben found the Omnitrix and it put itself on his wrist. In Ben Again and Again, the Omnitrix was removed from Ben's wrist due to the timeline changing.

  • Active Mode is the Omnitrix's default mode. The Omnitrix can only let the wearer be in the body of an alien for 10 to 15 minutes at a time. The Omnitrix appears to time in and out at random times on occasion.


  • When the watch times out, the faceplate turns red and recharges for around 5 minutes.[2] When it is green again, the user can transform again. The Omnitrix is powered by the Omni-Core within the device.[3]
    • The Omnitrix can instantly recharge either in response to a direct physical threat to the user or by inputting a certain code sequence. Thus far, only Kevin as Dark Matter knows this code sequence.[4]



  • The Omnitrix contains the DNA of millions of aliens from across the galaxy[DR 1][5] and can transform its user into one of them for a limited period of time. Only ten of these DNA samples can be available at any given time, as only ten can be loaded into the loading bay unless the setting to allow more than ten is changed.[DR 2]
    • Alien DNA is "injected" into the user, meaning they retain the wielder's personality, memories, and consciousness.[DR 3][6][7] Because of this, most of the aliens are not full-blown aliens, with the exception of Ectonurite and Conductoid DNA.[DR 4]
    • The DNA samples are contained in DNA pods with a small forcefield that keeps the DNA contained but allows the user to pass through it. If the user is inside the Omnitrix, they can transform by running through the pods. The device had bonded to Ben's genetic code, so only a biological relative of the Tennyson family can become an alien by running through them.[5]
    • The user can access the entire cache of aliens by cycling in new chambers and replacing the others. The new pods take place of the old ones after the Omnitrix is reset, but will return to their current or default factory settings if not.[DR 5]
      • The user can temporarily access aliens not present in the active playlist[DR 6] by pulling up on the device's faceplate instead of pushing down. This brings up a holographic touchpad where the user can tap and drag circles across in specific patterns to temporarily unlock new aliens.[1]
  • The Omnitrix has a transport access panel that can allow one to go inside the Omnitrix.[6]
  • The Omnitrix has recalibration mode, as it updated three times.[8][5][9]
  • The Omnitrix has a sort of reboot mode to repair it when tampered with.
  • The Omnitrix can be programmed to respond telepathically to its user.[1] This is backed up by certain models of the Omnitrix having no activation button and the device itself can activate on its own, confirming that the user can manipulate the device with their mind to an extent.
  • The Omnitrix has a DNA scanner, allowing it to sample, absorb, and collect DNA.[10][1]
  • The Omnitrix can repair mutated DNA and terraformed planets, as shown when Azmuth used it to revert Alien V back into Vilgax and restore Earth to its original state.[1]
  • The Omnitrix emits a frequency, even when not in use, so the user can easily be tracked using it.[11][12]
  • The Omnitrix has safeguards that prevent it from being possessed by an Ectonurite.[1]
  • The Omnitrix has a quick change feature, allowing Ben to change from alien to alien without touching the dial.[13]
  • The Omnitrix has an orange timer-like setting that was activated by Azmuth.[1]
  • The Omnitrix can give the alien transformations custom clothing loosely based on the user's current outfit.[14]
  • The Omnitrix can recalibrate itself to take on any of its previous appearances.[DR 7]
  • The Omnitrix has a failsafe release that detaches itself from the users wrist, should the user be critically endangered beyond the Omnitrix's help.[15][16]


  • The Omnitrix can translate any alien language into that of the user, such as when it translated the Incurseans' native tongue into English.[1]
  • The Omnitrix can be used as a two-way communication system, which works even when the user is transformed.[1]
  • The Omnitrix can track alien signals.[17][18]


  • The upgraded Omnitrix allowed the user to transform into enhanced versions of the aliens with the use of energy forms like Shock Rock.[19]
  • Upon the acquisition of the Omnitrix Key, the Omnitrix can provide its aliens with Omni-Kix Armors. By twisting the symbols on their bodies 90 degrees, the alien forms will be armored in robotic suits boosting their natural abilities and adding new powers.[9]
  • The Omnitrix can provide its aliens with Omni-Naut Armors. By twisting the symbols on their bodies another 90 degrees, the alien forms will have their Omni-Kix Armors reformatted into special robotic suits that allow them to survive in the vacuum of space[1] and aquatic environments.[DR 8] They can alternatively be activated automatically when the user is already in space.[DR 9]
    • For aliens who can naturally survive in space such as Jetray, the Omni-Naut Armors will give them added protection.[DR 10]

Omnitrix Symbol Position

  • The Omnitrix symbol is generally located on the chest of the transformations.
    • Grey Matter and Slapback wear their Omnitrix symbols on their backs.
    • Heatblast wears his Omnitrix symbol on his collarbone.
    • Alien X wears the Omnitrix on the right side of his chest.


  • The Omnitrix may or may not give clothing to a transformation. Even when it does, the clothing seems to be random:
    • Diamondhead has black-and-yellow clothing.
    • XLR8 has black-and-blue clothing.
    • Four Arms and Gax have white-and-black clothing, similar to 10/11-year-old Ben's transformations from the original series and Omniverse flashbacks.
    • Slapback has white, blue, and black clothing.
    • Grey Matter and Mole-Stache have green-and-black clothing, similar to 16-year-old Ben's transformations from Omniverse.
    • The rest appear to be unclothed, similar to 15/16-year-old Ben's transformations from Alien Force and Ultimate Alien.


  • If fiddled with, the Omnitrix can start turning users into hybrids of multiple aliens.[20]
  • When struck by lightning in close proximity with Xingo, Omnitrix aliens and their powers can become cartoonish.[21]
  • The Omnitrix is vulnerable to electromagnetic interferences, such as that created by Polar and Solar Twain, so the user will randomly switch from one alien to another and/or experience delayed transformations until the electric/magnetic interference is gone.[22][23]
  • The Omnitrix is vulnerable to stormy weather, making the user unable to transform for a short period.[24]
  • Having more than 10 DNA pods in the loading bay can cause the user to randomly and uncontrollably switch from one alien to another.[25]
    • The only time this has occurred was because Vilgax, who knows how the Omnitrix works, used his DNA as an inside man to activate Gax's chamber.[26][DR 11]
  • If the Omnitrix symbol is removed while the user is transformed, the ability to transform back to normal is removed.[27]
  • As a side-effect, the Omni-Kix feature will cause the Omnitrix to use more power and consequently time out faster.[11][9]
  • When infected by Nanites, the Omnitrix will release alien DNA and turn other human beings into aliens. This can only be reversed by removing the Nanites.[28]
  • The Omnitrix in Evil Ben's dimension can release a fatal shockwave when hit by the strength of a Tetramand's level a number of times, turning the user into Alien X while vaporizing everyone around them.[16]
  • The failsafe feature can be easily exploited by a Celestialsapien, as demonstrated by Alien X.[16]

  • Basic Omnitrix
  • Deluxe Omnitrix
  • Omnitrix Creator
  • Omni-Strike Omnitrix


  • Although the Omnitrix does not have enough room to contain the DNA samples of every sapient race in the universe,[DR 13] every canon alien confirmed to have been catalogued in the prototype Omnitrix from the Classic Dimension is present in this Omnitrix.[DR 14][DR 15][DR 16]
  • Duncan originally stated that this Omnitrix cannot collect new DNA by scanning other aliens.[DR 17] However, the statement was later refuted[DR 18] in order to avoid spoilers for Ben 10 Versus the Universe: The Movie. He also stated that the DNA of aliens such as Ampfibian, NRG, and Kickin Hawk will "get added later".[DR 19]
    • As such, it is possible for Ben to regain Upgrade by scanning the DNA of another Galvanic Mechamorph.[DR 20] Presumably, this also means that he can regain Gax by scanning the DNA of another Chimera Sui Generis.
  • Originally, the Omnitrix could only have ten accessible aliens at a time.[JF 1] As of Ben 10,010, that has been changed.[DR 21] The reason for this in-universe is unknown.
  • Though Duncan previously stated that this Omnitrix cannot repair DNA,[DR 22] Azmuth used a feature similar to the original Omnitrix's DNA repair mode to revert Alien V back into Vilgax.[1]

DNA pods.png

  • Crossover Nexus features Ben transforming into characters from nearly every Cartoon Network original series, a side effect of the Omnitrix being recreated by Strike's blaster. However, these forms can only be accessed in the Nexus Realm.[DR 23]
  • A scrapped power-up for the Omnitrix had Ben's aliens generating shadow versions of themselves.[DR 24]
  • Phil clocked the Omnitrix's transformation process at 100 google yattabytes per .000000000001 cubed second. As far as any sub or superluminal matter in the universe, the Omnitrix operational speed easily surpasses the once theoretical, faster than light, tachyon particle.[DR 25]
    • This is as fast as any Galvan equipment can clock it, but it could be faster.[DR 26]
  • The crew looked long and hard at the original lineup of the Classic Dimension when deciding which aliens to include in the roster for Season 1.[DR 27]
  • It was first hinted by Duncan that aliens that were removed from the active playlist (excluding Upgrade and Gax) would return in a future season,[DR 28] foreshadowing the events of Ben Gen 10.
  • The out-of-universe reasons for the Omnitrix having a new appearance every season are to repurpose unused designs from pre-production, to differentiate one season from another, and for marketing purposes.[DR 29]
  • It is unknown if this Omnitrix has a self-destruct feature like in the Classic Timeline.
  • Even though a reference image exists for a more detailed Omnitrix core, the Omnitrix itself has a more simplified T-shaped circuitry pattern from Season 3 onwards.
  • The Omnitrix from the dimension where Gwen goes to a summer school instead of the road trip with Ben and Max is modeled after a scrapped concept for the primary Omnitrix's design as of Summer Breakers.
  • The Season 4/5 Omnitrix's tubes glow green when selecting and transforming into a alien.
  • The Omnitrix from Season 1 looks exactly the same as prototype Omnitrix from Original Series.


  1. Upgrade was removed when he merged with the Omnitrix and fused with Ben's DNA (thus becoming Glitch) in order to avoid destruction in Omni-Tricked: Part 4.
  2. Gax was unlocked by Vilgax in Omni-Tricked: Part 1. He was removed[DR 12] when Vilgax absorbed his DNA in Omni-Tricked: Part 3
  3. Appoplexian DNA was used by Dr. Animo in Animorphosis even though Rath was locked during Season 2.
  4. 4.0 4.1 Beginning in Ben 10 Versus the Universe: The Movie, Ben can temporarily unlock new aliens by pulling up on the Omnitrix's faceplate and interacting with the holographic touchpad. These aliens are not a part of the active playlist.
