Ultimate Forms

Ultimate Forms are evolved forms of some of the aliens found in the Ultimatrix. Some of them have completely changed their physical appearance, while some simply change their color with some minor extras. However, all Ultimates have enhanced powers/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 (according to Dwayne), evolving the alien.

This "survival of the fittest" method of evolving the aliens makes the Ultimates more suited for combat. When Azmuth saw the modified Ultimatrix for the first time, one of his complaints about the Evolutionary Function was that it was "begging for trouble".

The Ultimate versions of the aliens have enhanced their main powers, but sometimes removed some of their secondary features/powers. Ultimate Swampfire's pyrokinesis and durability are better than Swampfire's, but he loses Swampfire's regeneration ability, Ultimate Spidermonkey is stronger than Spidermonkey, but he loses the second set of arms and lacks the tail, Ultimate Humungousaur can't grow as Humungousaur, Ultimate Echo Echo can not duplicate himself as Echo Echo.

Activation
To activate this, Ben presses the Ultimatrix symbol, causing it to grow four spikes. Ben is then consumed by green light and goes Ultimate.

The new Omnitrix is lacking the Ultimate evolutionary function.

Freedom from the Ultimatrix
In the episode The Ultimate Sacrifice, six of the sentient Ultimate Forms demanded their freedom from the Ultimatrix, causing Ben to almost sacrifice his own life to let them escape from the device. Ben almost died, but the Ultimatrix freed the Ultimate Forms before it was too late.
