Mizaru

Appearance
Mizaru resembles an Arachnichimp, but unlike the others, he appears to be just a little overweight, almost the shape of Ultimate Spidermonkey.

Apparently after escaping a Highbreed ship Simian makes a deal with Mizaru and Mizaru was infected by a Xenocyte Queen. At first, he struggled with the queen but retained his free will. From there he started infecting all Arachnichimps he could find. After a battle with Ultimate Spidermonkey, he is defeated and the rest of the world is rid of the Xenocytes. He swears to make his revenge. However, he was eaten by a Root Shark.

Trivia

 * He is named after Mizaru, one of the Three Wise Monkeys which sees no evil, seeing that only his eyes were covered by the Xenocyte Queen.
