Henny encountered the heroes in his grandfather's laboratory. Henny demanded to know why were they here and was told the heroes were interested in the robot. Henny introduced himself and turned on a video, which explained who Robon was and who was its creator. Henny clarified the robot, Robon, was made to plant seeds to revitalize the land, but it has not succeeded and wished Robon to give up, since no effort has been made. Clemont pointed out one must not give up and even managed to repair Robon. Chesnaught arrived to attack the heroes, but Henny explained they were here to help. With the help of his friends, Henny started digging a hole, where the rock was. While everyone was trying to destroy the rock, Team Rocket arrived and captured everyone, wanting to take Chesnaught. In the process, Robon sacrificed itself, taking hits from Jessie's Gourgeist and James' Inkay to keep Chesnaught unharmed, which made Chesnaught and Henny sad. Clemont managed to repair Robon, exciting Henny, who decided to become an inventor to repair Robon whenever it was needed.
