Spidermonkey

Spidermonkey is the Omnitrix's DNA sample of an Arachnichimp from the planet Aranhaschimmia.

Ben as Spidermonkey
Spidermonkey is an alien with four arms, four green eyes, two legs, three fingers on each hand and three toes on each foot, blue fur over a dark blue center, and a tail with a stripe design. Spidermonkey wears the Omnitrix/Ultimatrix symbol on his chest.

In Omniverse, Spidermonkey has six green eyes, his hair is flipped up, and wears two green sashes going across his chest. The two stripes on his tail have turned grey, and the fur on his head is spiky with gray stripes. His nose has now shifted to his forehead and its shape has changed. He continues to wear the Omnitrix symbol on his chest, but it is connected to the sashes.

Albedo as Negative Spidermonkey
Negative Spidermonkey looks just like Ben's Spidermonkey in Alien Force.

In The Final Battle: Part 1, Negative Spidermonkey has red eyes and his Ultimatrix symbol is red.

Powers and Abilities
Spidermonkey has the ability to expel webbing from his tail, which were once stated to be as strong as steel, however species with as much or more strength than a Cerebrocrustacean can tear it. He can shape these webs into slings, or to swing across vast distances.

Spidermonkey can stick to and scale vertical surfaces.

Spidermonkey has superhuman strength, as he was capable of using a lamp post to bat Ultimate Kevin up a few feet. He also has enhanced agility, and has enhanced hand-to-hand combat skills. It was mentioned in Simian Says that Arachnichimps, and thus Spidermonkey, have hearing superior to a human's.

Weaknesses
Spidermonkey can get tangled by his own webs.

Sometimes, villains can use Spidermonkey's webs to their advantage.
