Experiment 586 (Tank) is designed to eat a lot of metal, growing bigger with each bite. He has a face similar to Kixx and he also has a similar body and feet. His hands have 4 fingers and he has an armadillo-like plating on his back. He is mostly orange. Lilo asked Gantu to get Tank away from Stitch by capturing him, since it apeared that, at Tank's size, Stitch was no match for him. He was rescued in the episode "Snafu."
