Ultimate Ben

Ultimate Ben is the evolved form of Ben from the future. His appearance does not change, despite evolving, but it enables Ben to use any alien's powers without needing to change his physical appearance.

Abilities
While in this form, Ben would just pronounce the name of any alien he choses to transform to and press the Ultimatrix symbol on his chest. While Ben's human appearance does not change, it changes depending on the size of his chosen alien, as seen where he accessed Ultimate Humongousaur's powers, where his body frame increased to fit the form.

Aside from his main powers, Ultimate Ben also gained access to his Anodite powers, though he says this is from spending 20 years with one. The possibility that he knows more than he let on so they may be that Ultimate Ben may have more abilities than his Ultimatrix Aliens.

Trivia

 * Because this form is linked heavily to the Ultimatrix, it is unkown if this form is the Ultimate Human form.
 * Ben staying in this form most of the time reflects his alternate form from the Original series. The only difference is that he is still reconizable as Ben in this form.
 * Ben says that he hasn't transformed into another Alien for years since he discovered his Ultimate Ben form, the other having become unneeded since he can use all of their abilities from this single form.
 * The abilities he attained while in his Ultimate Human form are his human adaptability as said it is a ability that excels all species. http://dwaynemcduffie.com.lamphost.net/forums/viewtopic.php?f=2&t=314&p=3063&hilit=adaptability#p3063
