Potis Altiare

The Potis Altiare is a device that enhances the powers of the Omnitrix/Ultimatrix, created by ancient Galvans. In Cosmic Destruction, six pieces of it are scattered around the world. At the end of Cosmic Destruction, Ben uses it to power his Way Big form to defeat Evil Way Big. According to Azmuth, work actually began on the science that eventually created The Omnitrix long ago by Azmuth's ancestors, the ancient Galvans; instead of creating the Omnitrix, they created the Potis Altiare which is capable of amplifying ones natural abillities, similar to the keystone once used by Gwen. Realizing that the device was too dangerous, they decided to hide it on Earth since even if the inhabitants of the planet, humans, did find it they couldn't have possibly known what it was or how to use it because they were too primitive at the time. Unfortunately, upon entering Earth's atmosphere the ship carrying the device was destroyed and the device itself smashed to pieces. In-game, the pieces were found by various villains and boosted their abillities, or in one case animated a Terracotta Dragon and the Terracotta Army, and in another case turned the villain to stone when it was removed. It can only be used once, due to a piece that has been destroyed in Ben's battle against Cooper.
