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

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


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.

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.

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.

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



  • The Omnitrix contains the DNA of millions of aliens from all over the universe[DR 1][1] 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]
    • The DNA samples are contained in chambers. 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 those tubes.[1]
    • The user can access the entire cache of aliens by cycling in new chambers and replacing the others. The new chambers take place of the old ones after the Omnitrix is reset, but will return to their current or default factory settings if not.[DR 3] Ben was able to figure out how to temporarily access aliens not present in the active playlist from Azmuth.[DR 4][2] To do this, he pulls up on the device's faceplate instead of pushing down, which brings up a holographic touchpad. The user then taps and drags lines across in specific patterns to temporarily unlock new aliens.
  • The Omnitrix can only let the wearer be in the body of an alien for 10 to 15 minutes at a time. When the watch times out, the faceplate turns red and recharges for around 5 minutes. When it is green again, the user can transform again.
    • The Omnitrix can instantly recharge to protect the user from a direct physical threat.
  • The Omnitrix can be programmed to respond telepathically to its user.[2]
    • This is backed up by certain models of the Omnitrix have 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.[3][2]
  • The Omnitrix can repair mutated DNA, as shown when Azmuth used it to revert Alien V back into Vilgax.[2]
  • The Omnitrix emits a frequency, even when not in use, so the user can easily be tracked using it.[4][5]
  • The Omnitrix can instantly be recharged by inputting a certain code sequence; only Kevin as Dark Matter knows this code sequence.[6]
  • The Omnitrix can track alien signals.[7]
  • The Omnitrix can translate any alien language into that of the user, such as when it translated the Incurseans' native tongue into English.[2]
  • The Omnitrix has safeguards that prevent it from being possessed by an Ectonurite.[2]
  • The Omnitrix can be used as a two-way communication system.[2]
  • The Omnitrix has an orange timer-like setting that was activated by Azmuth.[2]
  • The Omnitrix can give the alien transformations custom clothing loosely based on the user's current outfit.[8]
  • The Omnitrix can recalibrate itself to take on any of its previous appearances.[DR 5]


  • The upgraded Omnitrix allowed the user to transform into enhanced versions of the aliens with the use of energy forms like Shock Rock.[9]
  • Upon the acquisition of the Omni-Kix 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.[10]
  • 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[2] and aquatic environments.[DR 6] They can alternatively be activated automatically when the user is already in space.[DR 7]
    • For aliens who can naturally survive in space such as Jetray, the Omni-Naut Armors will give them added protection.[DR 8]

Omnitrix Symbol Position

  • The Omnitrix symbol is generally located on the chest of the transformations.


  • 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.[11]
  • 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.[12][13]
  • Having more than 10 DNA pods in the loading bay can cause the user to randomly and uncontrollably switch from one alien to another.[14]
    • 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.[15][DR 9]
  • When struck by lightning in close proximity with Xingo, Omnitrix aliens and their powers can become cartoonish.[16]
  • If the Omnitrix symbol is removed while the user is transformed, the ability to transform back to normal is removed.[17]
  • As a side-effect, the Omni-Kix feature will cause the Omnitrix to use more power and consequently time out faster.[4][10]

  • The Omnitrix contains the DNA samples of every canon alien catalogued in the Omnitrixes from the Classic Continuity, even if most of them will not be appearing in the show.[DR 12][DR 13]
    • Aliens confirmed to have been available in the prototype Omnitrix between the original series and Alien Force will mostly appear in the series, as Duncan Rouleau believes the Omnitrix of the Reboot Continuity is the same as as the prototype Omnitrix.[DR 14]
  • Duncan originally stated that this Omnitrix cannot collect new DNA by scanning other aliens.[DR 15] However, the statement was later refuted[DR 16] in order to avoid spoilers for Ben 10 Versus the Universe: The Movie, which confirms that the Omnitrix can absorb the DNA of other aliens.
    • As such, it is possible for Ben to regain Upgrade by scanning the DNA sample of another Galvanic Mechamorph.[DR 17]
  • Duncan also previously stated that this Omnitrix cannot repair DNA.[DR 18] In Ben 10 Versus the Universe, Azmuth uses a feature similar to the original Omnitrix's DNA repair mode to revert Alien V back into Vilgax.

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 19]
  • The crew looked long and hard at the original lineup of the Classic Continuity when deciding which aliens to include in the roster for Season 1.[DR 20]
  • It is possible that any aliens that were removed from the active playlist (excluding Gax) might return for future seasons.[DR 21]
  • 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, as well as for marketing purposes.[DR 22]
  • It is currently unknown if this Omnitrix has a self destruct feature like in the Classic Continuity.


  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 10] 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 In Ben 10 Versus the Universe: The Movie, Ben learns to temporarily unlock new aliens by pulling up on the Omnitrix's faceplate to bring up a holographic touchpad before tapping and dragging lines across the touchpad in specific patterns. These aliens are not a part of the active playlist.
