The Ultimate Omnimatrix[citation needed], referred to as the Ultimatrix, was the device that Ben 10: Ultimate Alien used. Ben used it to replace the Omnitrix, which he destroyed in a battle with Vilgax. It can turn aliens into their ultimate forms by turning the omnitrix symbol when an alien. It’s got more modes like active, recharge, DNA Scan (to unlock more aliens), Reset, Radiation and Self-Destruct. You can still transform into aliens to fight bad guys. And use their new ultimate forms!
