I haven't bothered to for years. Not since I discovered my best transformation.

Ben 10,000 referring to Ultimate Ben

Ultimate Ben is the ultimate evolved form of Ben 10,000, just like his aliens have their ultimate forms.


Ultimate Ben looks exactly like Ben 10,000 in Ultimate Alien. However, rather than wearing the Ultimatrix on his wrist, he instead wears an evolved Ultimatrix symbol on his chest.

Powers and Abilities

Ultimate Ben is Ben's most efficient form due to the fact that in this form, Ben can use the powers of his aliens without transforming. This is done by pronouncing the name of any alien he chooses (though it is not necessary) and pressing the evolved Ultimatrix symbol on his chest, at which point he gains the powers of the selected alien.

Ultimate Ben's body can adapt to match that of the selected alien, such as when his body frame becomes larger while accessing Ultimate Humungousaur's powers.

Ultimate Ben's natural abilities are increased while accessing certain aliens' powers. These can be seen when he uses Spidermonkey's enhanced agility, Jetray's flight and enhanced strength, and XLR8's enhanced speed.

Ultimate Ben can fire green time rays from his hands capable of sending other beings across time and space while accessing Clockwork's powers.

Ultimate Ben can fire a powerful ice breath from his mouth that isolates targets in ice while accessing Arctiguana's powers.

Ultimate Ben can project blasts of fire from his hands while accessing Heatblast's powers.

Ultimate Ben can generate diamond constructs that can render time attacks useless and fire diamond shard projectiles from his arms while accessing Diamondhead's powers.

Aside from the ability to rapidly switch between alien powers, Ultimate Ben removes the physical vulnerabilities causes by the physiologies of certain alien species.
