Zach Varmitech

Zach Varmitech is the archenemy of the Kratt Brothers and the main antagonist in Wild Kratts. He kidnaps animals to put mind control helmets on them to help with his construction projects (which seem pointless since he usually tries to build things far from civilization), but his schemes backfire because of the Wild Kratts. Despite his schemes revolving around using animals for his own purposes, he is shown to be afraid of them as well. He has known the Kratts Brothers since they were kids. It is also hinted he may have a crush on Donita.
