Who Has Made the Omnitrix?

The Omnitrix was made by Azmuth.

Based on the provided reference, Azmuth is credited with creating the original Omnitrix. This device was a central element of the Ben 10 series from the first Ben Classic iteration up until the final episode of Alien Force.

The Creator of the Omnitrix

The reference clearly states: "Azmuth made Omnitrix which is from first ben classic till alien force last episode."

This identifies Azmuth as the brilliant Galvan scientist responsible for inventing the powerful alien transformation device worn by Ben Tennyson.

Omnitrix vs. Ultimatrix

While Azmuth created the Omnitrix, the reference also mentions another significant device and its creator:

• Omnitrix: Made by Azmuth. Used by Ben from Ben 10 Classic through Alien Force.
• Ultimatrix: Made by "Albedo". Used by Ben after the Omnitrix.

This distinction is important as Ben uses different versions or successors of the Omnitrix throughout the various series, and not all were created by Azmuth. The reference specifically attributes the creation of the original Omnitrix (and its usage timeframe) to Azmuth.

Here's a quick comparison based on the reference:

In summary, if you're asking about the original device capable of transforming Ben into various aliens, according to the reference, the creator is Azmuth.
