Ultimate Forms

Ultimate Forms are evolved forms of some of the aliens found in the Ultimatrix. Some of them have completely change 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), technically evolving the alien.

All Ultimate forms are 10 times more powerful than their non-ultimate counterparts.

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 "begging for trouble".

The Ultimate versions of the aliens enhance their main powers, but sometimes remove 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. Also, when someone asked if every alien has an Ultimate form, Dwayne answered "Wait and see", which is his way of answering a question that he is not ready to or doesn't want to answer, but it is confirmed there will be more.

Freedom from the Ultimatrix
In the episode The Ultimate Sacrifice, the 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.
