A tan naked mole rat-like experiment with four spines on his back. Designed to warp the fabric of time and space, causing the universe to collapse upon itself. 607 itself never actually appeared in the series, but he was the pod on the sandcastle in the episode "627"' '(although put x). Rufus the Mole Rat was mistaken for this experiment in the Lilo & Stitch/Kim Possible crossover episode until Stitch identified him as not being one of the "cousins". He is voiced by Nancy Cartwright.
