Zach Varmitech

Zachary "Zach" Varmitech' is the archenemy of the Kratt Brothers and one of the four main antagonists of Wild Kratts. Accordingly, he has known, the Kratt Brothers and Aviva since they were children in science camp and has since become a robotics expert. He commands a vast army of Zachbots who do whatever he says and kidnaps animals so he can put mind control devices on them to help with his construction projects (which seem pointless since he usually tries to build things far from civilization), but his schemes always backfire because of the Wild Kratts. He may also have a possible crush on Donita Donata as well.
