Revolutiontrix

The Revolutiontrix is the sequel Omnitrix to the Ultimatrix. It has 16 Xobots and is destroyed at the end of Season 4 in Ben 10: Xobot Revolution.

Ben got it at the start of the show. He had at first all 16 Xobots, but by the 2nd episode lost them all thanks to Kevin 10,000.

The First 2 Seasons is based on finding all 16.

It has all the previous aliens from Ben 10, Ben 10: Alien Force, Ben 10: Ultimate Alien, etc. It also has Dinowreck, Spikeleg, Aquaos, Cloudtin, and I think one more.
