Ultimate Forms

Ultimate Forms are the evolved forms of some of the aliens found in the Ultimatrixes. 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 and abilities.

Concept and Creation
The "Evolutionary Function" was an additional feature Albedo added to the Ultimatrix after stealing it from Azmuth. According to Dwayne McDuffie, 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, 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 it was that the Evolutionary Function was "begging for trouble".

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.

Freedom from the Ultimatrix
In The Ultimate Sacrifice, the six sentient Ultimate Forms demanded their freedom from the Ultimatrix, causing Ben to almost sacrifice his own life to let them escape. Ben almost died, but Azmuth freed the Ultimate Forms before it was too late. Then Azmuth lead them to a world where they would live in peace via portal.

Trivia

 * According to Dwayne McDuffie:
 * Ben is scared of the Ultimates, but thinks they are cool.
 * Ben felt discomfort when going Ultimate.
 * The Ultimates' DNA wasn't in the Codon Stream.
 * According to Derrick J. Wyatt, the Omnitrix won't take the Ultimates' DNA.
 * The first time the Ultimate function was used, Albedo turned the rim of the Ultimatrix symbol, causing the core to pop out, which he promptly pressed. In some instances, Ben turned the symbol slightly before activating it.
