It uncannily resembles the Ultimatrix, except it is blue instead of green
Ren obtained in the Awsomatrix had a watch store in Who Watches The Watchman?. In Attack of the Giant Frogs, the Awesomatrix absorbs the radiation out of a Mutants scientist which unlocks Swampfire's Ultimate form. In My Son, Diamondhead, Ren damaged the Awesomatrix by slamming the device against a tree. The damage caused Ren to stay in the Diamondhead form longer than usual. However, this was only temporary as it never happened again and Ren could transform for the regular 10 minutes.
The Awesomatrix is a combination of the Omnitrix and the Ultimatrix. It can only hold 10 aliens (until the others are unlocked), and you can only have the alien for 10 minutes, like the Omnitrix. However, you can turn the alien into an Ultimate form, like the Ultimatrix. It also shows holograms of the aliens you’ll choose instead of silhouettes.
