Dario is a nefarious boy who lives in the same village as Lara and he hired Team Rocket to cause an 'accident' to remove Lara from the Pokémon race so he would have a better chance at winning himself. He boasted to
Lara Laramie that he was going to win the race but
Lara Laramie retorted and told him that the race couldn't be won on just speed alone.
Misty thought
Dario was quite despicable even before she knew that he was in cahoots with Team Rocket but
Lara Laramie explained that he was a pretty skilled competitor.
Team Rocket managed to stir up
Lara Laramie's Tauros and
Dario quickly showed up in town making it look like he was being helpful by telling her that something wrong with her Tauros. Team Rocket spooked
Lara Laramie's Ponyta and
Lara Laramie ended up injuring her arm.
Dario reported in with Team Rocket and complemented them on a splendid technique as no one suspected that he was responsible for
Lara Laramie being out of the race Pokémon.
During the Pokémon race,
Dario raced on his Dodrio and Team Rocket continued to help him try to win the race by laying traps to knock out his competition one by one.
Dario lead the race for almost the entire time but he revealed half way through the race to
Ash Ketchum and
Misty that Team Rocket was working for him and that seemed to motivate them to make sure one of them one the race instead of
Dario. In the home stretch,
Dario ended up loosing the race at the finish line to
Ash Ketchum and
Lara Laramie's Rapidash but
Dario was a poor sport and a bad looser and he decided to attack
Ash Ketchum and
Lara Laramie's Rapidash but
Lara Laramie's Rapidash ended up kicking
Dario and
Dario's Dodrio off into the distance.
