Tim meets Detective Pikachu shortly after arriving in Ryme City in order to look for his father, Harry Goodman, who had disappeared in a car accident two months earlier. Prior to the events of the game, Tim passed the admissions test to attend Ryme University in the fall. Together with Pikachu and the Ryme City Detective Agency, Tim solves various puzzles and mysteries.
Tim Goodman appears as one of the protagonists of Detective Pikachu. Tim was once an aspiring Pokémon Trainer, but in his own words, it "didn't really... work out". Haunted by painful memories, Tim feels that he does not need a Pokémon partner. While in Ryme City, at the home of his missing father Harry, Tim meets Detective Pikachu and, after discovering a mysterious ability to communicate with him, reluctantly teams up with him to find Harry, eventually joining forces with a journalist named Lucy Stevens and her partner Psyduck.
