Diamond & Pearl arc
Dr. Footstep observed Diamond, Pearl and Platinum coming to Lake Valor. He chuckled, as he managed to obtain Pearl's Chatot's footprints. After Diamond and Pearl had a battle against a lady and a gentleman at the lake's restaurant, Dr. Foostep arrived, ordering everyone to stop, as he took footprints of Infernape and Torterra. The waiter explained that was Dr. Footstep, who took the group to his house, filled with plaques of footprints he had been collecting. Dr. Footstep explained that he was analyzing footprints, which could tell him the Pokémon's feelings and thoughts. Looking at Chatot's footprint, he noted it and Pearl were really close. As Dr. Footstep admitted he wanted to get a footprint of a Hippowdon, one just appeared outside his house. However, Hippowdon was not pleased its legs got stuck in Dr. Footstep's paper, and blew the group away with a tornado.

The torando caused the group to fall near the lake, where Pearl and Dr. Footstep got separated from Diamond and Platinum. Thus, Pearl took Dr. Footstep to find the missing people. While trying to find them, Dr. Footstep found a footprint, and ignored Pearl, who reminded their mission was to find the missing people. Dr. Footstep looked at the footprints, which belonged to a Staravia, and felt some Staraptor must be nearby, too. He saw one, and tried to get its attention, only for Staraptor to take him away into mid-air. Pearl and his Chimler managed to lace on Staraptor, and Pearl noted its amazing strength to carry so many people at once. Dr. Footstep analyzed Staraptor's footprint, and noted it is getting tired of them, and would likely drop them. Pearl was terrified, for they would fall down in the lake. Pearl demanded Dr. Footstep to cheer Staraptor up, and the two flew past by Diamond and Platinum.

Dr. Footstep and Pearl fell in the lake, and used a log to swim to the lake's island, where they encountered Diamond and Platinum. Dr. Footstep looked at the two scientists, who fought Diamond and Platinum, and examined their Drapion's footprints, and explained it didn't like its trainer, and wished to be outside in the wild. He went to analyze Kricketune's footprint, but Pearl stopped him, since they got the idea. The next day, Dr. Footstep took the two scientists away to the police station, but his focus shifted as he encountered a Weavile.
