Azmuth created it as the first prototype of the Omnitrix. It was stolen by Troconnuese and it landed in Medieval England. A wimp named Paul found it and he could transform into 6 aliens.
Prototrix is a primitive version of the Omnitrix, due to it being a prototype. It can only transform into aliens, not any other functions. Unlike the Omnitrix symbol, the Prototrix symbol has a diamond instead of a hourglass, which appears on other aliens too.
- Can transform into 20 aliens (6 unlocked)
- After the episode Dark Forces, a bit of the dark energy was left in the Prototrix. Azmuth fixed it up so that when Paul presses the Prototrix symbol, it would "darken" the aliens and give them Dark Forms. Only three aliens can do that.
