Recently, I decided to rewatch Ben 10 I became interested in certain aspects of the Omnitrix.

How does the Omnitrix convert a human (or any other species for that matter ) into another species. I know it has something to do with genetic manipulation but how does the Omnitrix go about doing that? To say it's some form of energy as some have suggested to me seems a little far fetched. Other say, it uses some form of virus that infects the user with foreign alien DNA, but that sounds even more far featched. Can anyone help is there something I'm missing

    It uses magic and Phlebotinum. I'm not joking- even in-story, its creator doesn't know how it works. – Yasskier Jul 11 '17 at 4:57
  • @yasskier I find that hard to swallow as well the Omnitrix is obviously a form of technology with the holograms, and signals from Primus. I find it harder to believe that Azmuth creator of the Omnitrix Ultimatrix Unitrix and the Omnitrix 2.0, smartest being in three (arguably 4) galaxies has no idea what makes the Omnitrix work. Also gwen tennison even said herself magic isn't really it's really just manipulation of mana – user85749 Jul 11 '17 at 5:11
  • @user85749 - Whether it’s got a fancy Austronesian or Hebrew name or not doesn’t really change what it is.... – Adamant Jul 11 '17 at 5:42

    I read it fast and I'm tired, so I thought this question was going to be about my namesake. :P – Arya Jul 11 '17 at 6:10

    I may be late to this discussion but I believe the canonical answer is, "Very well, thank you for asking." – Cadence Aug 30 '18 at 23:03

Canonically, no one actually knows except for Azmuth. When it comes to the Omnitrix, Azmuth refuses to answer what the processes for anything but collecting DNA from aliens actually are, and since Ben doesn't really care to investigate it and just cares about it working, we'll likely never truly know the how or why of the Omnitrix. Ben 10 is based off of Ben's perspective, nothing more, nothing less, and as such we don't know anything other than "the Omnitrix turns the user into aliens." That's been my experience, at any rate.


Here's my hypothesis: the Omnitrix communicates with Primus via quantum entanglement, downloads a set of instructions for nanobots which then reconfigure the user's anatomy and DNA to match the organism the user transforms into. The nanobots undo everything they've done when the user turns back. Since the user is able to retain their mind, but different species' brains are bound to work differently especially if they're from different planets, I also think the Omnitrix might scan the user's brain patterns to make sure they're still themselves after transforming

    Do you have any evidence for this to back up your theory that you can edit in? – TheLethalCarrot Feb 5 '19 at 22:11

Theory: It injects alien DNA from its library that has been altered to mix with other DNA then it rapidly evolves this DNA sample until Ben mostly alien. Ben turns back with unaltered DNA so he's 100% human again.


I think the omnitrix is injecting The Alien DNA into the user

    Hi, welcome to SF&F. The question notes this possibility, but considers it "far fetched." Can you provide any evidence that this is the case? – DavidW Dec 12 '20 at 0:05
