Hi-tech is leading a group of technogangsters on a break-in at a Government Lab. The object of their quest? A proton accelerator, but the Turtles and Carter are there waiting for them. The Turtles are ticked off at Carter because, once again, he didn't play like a team member. Carter is angered by their criticism and takes off on his motorcycle. Back at the lair, while Leonardo is unable to locate the Dreggnaught with their tracking equipment, Donatello continues to express concern about the results of his testing of the unstable mutagen. Out of the blue, April contacts them to let them know that Dregg has landed on Earth and is preparing a press conference. The Turtles rush to meet April at the Park, where they hear Dregg announce his friendly intentions and offers the world his molecular converter, a device that will take pollution down to zero.
