However, the Omnitrix still powered down when Cannonbolt rapidly depleted it of all of its power faster than it could recharge by turning several DNAliens back into humans from a distance. After the Master Control was deactivated, these 4 aliens were appended to his Alien Force list of aliens. He used aliens from the original series such as Way Big and Cannonbolt (as well as Wildmutt off-screen as confirmed by Dwayne McDuffie) and Murk Upchuck. The Master Control reappears in War of the Worlds when Azmuth activates it by voice command to grant Ben all of the Master Control abilities from the original series as well as unlocking every single alien in the Omnitrix. But Ben, who turned off the Master Control, accidentally transforms into Grey Matter and tries to turn back, but fails.The Master Control makes another appearance in Ben 10,000 and Ken 10, being used by Ben 10,000 and later also by his son Ken. After a long chase, they finally get the Omnitrix until Gwen tricks them and gets the Omnitrix back.

After this, he ruins some pictures and causes more trouble until Vilgax and Kevin 11 come to steal the Omnitrix, until Grandpa Max sends them into the Null Void, with Vilgax trapping Diamondhead along with them. He then stays Stinkfly for hours (showing off his unlimited timing) and ruins Gwen's ice cream, who's extremely annoyed by his new powers. When a man falls off the boat, Ben uses Ripjaws to get him out of the water, then Stinkfly to fly on back to the boat.

The Master Control was first used in Back with a Vengeance. Ben unlocks it by accident when on a boat trip.
