The Potis Altiare is a device that was created by the ancient Galvan as a device capable of multiplying one's natural abilities several times over.
The Potis Altiare looks almost identical to the Omnitrix, which is located at the top of this device. It is green in color and resembles mechanical materials. There are gear-like stripes running behind the Omnitrix symbol, and green wiring around it. There are black marks surrounding the symbol, as well as leaf-like edges. Once Ben transforms into an alien using it, the Potis Altiare is positioned on the Omnitrix symbol.
According to Azmuth, his work began in the interest of the sciences that eventually created the Omnitrix and Ultimatrix long ago by Azmuth's ancestors, the ancient Galvan. Realizing that the Potis Altiare was too dangerous, they decided to hide it on Earth since even if the primitive humans found it, they wouldn't know how to use it. Unfortunately, upon entering Earth's atmosphere, the ship carrying the device was destroyed and the device itself was torn to pieces. The pieces were found by villains and greatly enhanced their powers (though one piece turned Enoch to stone when it was removed). It can only be used once if a piece is missing.
- The Potis Altiare seemed to get Ben excited, making him ask tons of questions after timing out only to be disappointed when it had disintegrated after Ben defeated Evil Way Big.
