Shingo is a character of the day who appeared in Wired For Battle! (EP142).

He is the son and student of a great Pokémon Trainer that was once an equal of the Elite Four, Muramasa. Shingo maintained a laptop database on all other Pokémon Trainers who were registered with the Pokémon League.

Shingo saw most battles as a waste of time, operating under the belief that he could predict the outcome of any battle just by analyzing the data on his database. Team Rocket attempted to steal the database, but his Scizor swiftly defeated all five of their Pokémon, prompting Ash to convince him once again to battle him by pointing out that data couldn't predict how the battle would affect the Trainer.
