Spidermonkey

Spidermonkey is one of Ben's aliens introduced in Ben 10: Alien Force.

Ben first transforms into Spidermonkey when he has to fight off his Anodite grandmother in the episode, What Are Little Girls Made Of?.

Abilities
Spidermonkey is an alien with 4 arms, 4 eyes and 2 legs, a feature Spidermonkey has in common with Fourarms and Wildmutt because he is beast-like as well. Spidermonkey can spin webs from his tail (seemingly inspired by Stinkfly's ability to eject sticky goop) which were at one point stated to be as strong as steel. However, they have alse been shredded on a regular basis, and so this seems somewhat unlikely. (A note: his webbing is obviously not as strong as earth spider webbing, per thickness). He has supernatural adhesive skills, and has superhuman agility. Also, he surprisingly can swim. In the episode Birds of a feather, Simian(an Arachnichimp), said that their ears are better than humans, so he may have a highly strong sense of hearing, too. He is also good at hand-to-hand combat (no pun intended).

Weaknesses
Although incredibly agile, it can get tangled by its own web. This form may be agile but it does not have great strength so Ben tends to out smart enemies with it. In the episode The Final Battle: Part 1, it is shown that things can stick to Spidermonkey's fur by webs when Grandpa Max threw a pan at Albedo in Spidermonkey form.

Origins
Spidermonkey is an Arachnichimp from the planet Aranhaschimmia. The name "Arachnichimp" is derived from arachnid, the name of a group of animals including spiders, scorpions, and ticks, among others, and chimpanzee, a type of ape. Oddly, Spidermonkey has a tail, a feature chimps(and indeed, all apes) do not possess. It has also been stated that he is a marsupial, though Ben's male form likely has no outward traits of this.
