Doctor Mindbender’s attempt to create another human/Bio-Viper hybrid appeared to be a failure at first until it ends up reassembling in the New York City sewer system. When Duke, Roadblock, and Ripcord go along with Tunnel Rat to his hometown of Brooklyn to find a missing child named Reggie, they encounter the Sewer Viper being pursued by Doctor Mindbender and some Bio-Vipers on Cobra Commander’s orders. Doctor Mindbender also tries to reclaim Ripcord back as Patient X at the same time. In the end, the hybrid removes the control chip allowing Ripcord control of his Bio-Viper mutation and Tunnel Rat visits his parents, going around the back to avoid MPs in front.
