Javier is a boy who lives in the Sonoran Desert and was also voiced by Charles Vandervaart. He appeared in the episode Gila Monster Under My House where he discovered a gila monster was living under his front porch. He was scared, so he called the Wild Kratts for help claiming that gila monsters were dangerous because his grandfather told him that if one bit you it wouldn't let go until the sun went down. But afterwards Chris and Martin showed him that they weren't all to be afraid of and while they did have a poisonous bite, that they are normal lizards who want to be left alone.
