Ultimate Forms are the evolved forms of some of the Ultimatrix aliens, used primarily in Ultimate Alien and in Season 4 of Omniverse. All Ultimates have enhanced powers and abilities.

Concept and Creation

The "Evolutionary Function" was an additional feature Albedo added to the Ultimatrix after stealing it from Azmuth. The Evolutionary Function works by placing the DNA of the alien in a certain simulation, making it suffer the worst possible scenario in millions of theoretical years in order to "force" evolution in the genetic code in the virtual environment; the evolutionary developments are then modified into the existing DNA.[DM 1]

This "survival of the fittest" method of alien evolution makes the Ultimates more suited for combat. When Azmuth saw the modified Ultimatrix for the first time, he said that the Evolutionary Function was "begging for trouble".[1]

The DNA of the Ultimate Forms was stored locally on the Ultimatrix and not in the Codon Stream.[DM 2] The Omnitrix won't take the Ultimates' DNA.[DJW 1]


Ben's Ultimatrix

To activate the ultimate form, Ben transforms into an alien and then presses the Ultimatrix symbol, causing it to grow four spikes. Ben is then consumed by green light and goes Ultimate. Ben generally uses the Ultimate feature when normal alien's powers are insufficient for the situation at hand.

Albedo's Stabilizer Ultimatrix

To activate the ultimate form, Albedo selects an alien and activates the transformation function, just like on all versions of the Omnitrix/Ultimatrix. Unlike them however, he is immediately transformed into the Ultimate form of that alien without the need to activate the function while already in alien form; instead of green light, Albedo is consumed by red light, his signature color. Whereas Ben usually reserves the Ultimate feature as a last resort, Albedo seemingly replaces the devolved forms of his aliens with them in order to gain the upper hand whenever he and Ben do battle.

Sentient Forms

Originally, the Ultimatrix contained sentient beings inside who were living versions of six of the Ultimates. These were:

In The Ultimate Sacrifice, the six sentient Ultimates demanded their freedom from the Ultimatrix, causing Ben Tennyson to almost sacrificing his own life to let them escape. Fortunately, Azmuth freed the Ultimate Forms before it was too late. Azmuth then led them to a world where they would live in peace via a portal.
