Ultimatrix

''"I kept the Ultimatrix after defeating Diagon and Vilgax." -'' Ultimate Ben 10,000.

Description
The Ultimatrix was created by Azmuth and then stolen and completed by Albedo. This Ultimatrix comes from an alternate timeline where Ben Tennyson kept the Ultimatrix after defeating Vilgax in The Ultimate Enemy: Part 2. Ultimate Ben 10,000 mastered the Ultimatrix and can transform into any alien with a single thought.

Appearance
The Ultimatrix's appearance changed twice. First it was a gauntlet and in the future Ultimate Ben 10,000 changed it to look like the prototype Omnitrix. Now the Ultimatrix looks similar to Albedo's Ultimatrix seen in Ben 10 Omniverse.
