Ultimate Spidermonkey

Ultimate Spidermonkey is the evolved form of Spidermonkey in Ben 10: Ultimate Alien. Ben first becomes Ultimate Spidermonkey in the episode Fame to fight Bivalvan, so he is Ben's second ultimate transformation. He is voiced by Dee Bradley Baker.

Appearance
After evolution, he loses his tail, and his extra pair of arms, while they get replaced with two pairs of spider legs. He now has a gorilla-shaped body, and he is larger than the original Spidermonkey. He also has six eyes, black fur, purple skin, and shrunken legs. He speaks in a deep-sounding voice.

Abilities
He can still climb/stick to walls, but now, the evoultion has given Ultimate Spidermonkey super strength. By splitting his lower jaw in two halves, he can shoot webs from his mouth, much more than Spidermonkey can shoot from his tail.

Trivia

 * When Spidermonkey evolves, he first gains gorilla-shape body and then the spider legs sprout out of his back.
 * This is the second ultimate form Ben has become, the first being Ultimate Swampfire. (Ultimate Humongousaur was first used by Albedo, so it would be the third seen, but only the second used by Ben.)
 * The legs of Ultimate Spidermonkey bear a minor resemblance to those of Iron Spidey, in the Marvel Comics Universe.
 * Ultimate Spidermonkey has a major resemblance of The Scorporilla, from Crash of the Titans and Mind over Mutant from Crash Bandicoot.
 * He is the first evolved form to be appeared in Ben 10:Ultimate Alien
