Max sends a message to the plumbers where Ben's attacking Max at a space station. Alan, Helen, Manny, and Pierce arrive to the space station and plan to stop Ben. Pierce suggests they work and stay together, but no one listens. Helen, the first to leave the group, finds Ben, but is defeated by his Echo Echo form. Later the team splits into two. Alan and Pierce get separated and Pierce ends up getting attacked and beaten by Goop. Later Manny and Helen get separated and get attacked and beaten by Rath. Helen, Manny, and Pierce regroup and try to find Alan. Alan soon finds Ben where he is attacked by Big Chill. Pierce, Manny, and Helen rescue Alan and try to beat Ben, but he manages to escape. Pierce suggests they work and attack like a team. Soon they find Ben, who goes Humongousaur at full size and fights the Plumbers Helpers. They soon suggest to attack Ben at once and throw Humongousaur into space. Because Humongosaur's weight threw off the balance of the ship's gravity control backup systems, realize the ship is crashing to London, so they sacrifice themselves for earth by self-destructing the ship but it doesn't explode. Max and Ben tell them that it was a test except the part with the space station crashing to London, and that they're soon heading to the Plumbers' Academy.
