This Ben 10 version will be quite similar but different story lines compared with the previous Ben 10 versions. Ben Tennyson has been abducted by aliens but raised them to space when he was ten years old, then he met Rook Blonko, where the aliens took both Ben and Rook to the Rooters military camp, where they're trained kids into soldiers. Ben was selected because founded the Omnitrix crash landed on Earth right after both of his parents died in a car crash while Rook was selected because he was orphaned after Vilgax and his armies invaded then destroyed his home planet then being rescued by the Rooters. Both Ben and Rook are being raised and trained together at Rooters military camp.

This version of the Rooters are more deadlier (unlike the one's from Ben 10 Omniverse). Rooters in this universe are a top secret Black ops team to train orphans into soldiers for infiltrate, assassinate, sabotage, and others. Back then, Ben and Rook was taught how to use their weapons, hand-to-hand combat, infiltrate, sabotage, & flying and hijacking spaceships (makes Ben and Rook the best pilots in the galaxy). But the Rooters will do anything to complete their mission. Once Ben grown older, he realized that the Rooters doesn't kept universe safe, but doing things for their own gain. Ben convinced Rook to bring down the Rooters organization and Ben was able to do so with all the harsh training he's been through plus the power of the Omnitrix to transform into different kinds of Aliens.

Ben has been wearing the Omnitrix since ten years old. But when he grew older, he finally recieved a better version which is the Ultimatirx which he currently wearing.

It will be taller than regular Grey Matter and able to have enhance strength and agility, super intelligence, and able to secrete a dark red cerebrospinal fluid which he can harden into a plaque and manipulate it to form weapons resembling the red crystal produced from his fireballs), Ultimate XLR8, and Ultimate Heatblast (I've added Ultimate XLR8 and Ultimate Heatblast at this version because I think that both XLR8 and Heatblast should have their ultimate form)

(The characters like Rover the Hare and Kasha are brand new)
