Ben 10 Alien Force Potis Altiare

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.

In Cosmic Destruction, six pieces of it are scattered all over the Earth. In the end, Ben uses it to power-up Way Big to defeat Evil Way Big.
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.
