Dody first appeared as a Doduo in Do Do that Doduo, riding Yellow around in her search for Red's Pika. He is later sent out to battle against Professor Oak's Spearow in order to test Yellow's skills. Doduo uses Whirlwind to stop Spearow's Fury Attack from landing. Oak responds with Mirror Move and the two birds arrive at a stalemate. At this Doduo dashes around Spearow, and amidst the spinning of the Whirlwind Spearow loses its balance, plummeting towards the ground to be caught safely by Pika. Yellow then explains to Professor Oak that she won the battle without anyone getting hurt. Oak notices that Yellow battled with a high level of control and accepted she might be able to save Red.
In Do Wrong, Dewgong!, Lorelei attempts to steal Pika from Yellow. Dody uses Drill Peck to break her ice slide, allowing the group to run away and hide. After figuring out how to escape Dody was used as the group's escape, using his fast speed to run them away.
In Paras Sight, Dody battled alongside Ratty against Super Nerd Miles in an attempt to rescue Pika. Completely pinned by Miles's attack, Yellow decides to give herself up to Marowak's Bonemerang, recalling Dody and Ratty before taking a direct hit to the chest. Although injured, Yellow attaches Dody and Ratty's Poké Balls to the bone, which come swinging back at him. Dody and Ratty then get released and help Pika to escape. When Miles pursue them the three release a combo attack, with Ratty breaking apart a nearby building with his teeth, Dody kicking them in the air, and Pika electrifying them and sending it at Miles, defeating him.
In Eradicate Raticate!, Dody is sent out alongside his teammates to battle against Lance and his Dragonite. Dody attacks with a powerful Peck, but Dragonite simply shrugs it off and throws Dody away. He is later used in a team attack to try and stop Lance from shooting bubbles. Yellow had Kitty cover the volcano crater in String Shot to form a net that is doused by her Omny's water, linked to Ratty's sensitive whiskers. Upon Lance triggering the net, Ratty signals to Pika to send electricity down the net, forcing Lance's bubble into view. Yellow then orders Dody to break the bubble with Drill Peck, but the attack proves too weak.
Dody was last seen in Bested by Banette, where he was intended to help battle against Sird and Orm. Before getting the chance to fight though, the two capture Silver and leave.

Dody has a strong relationship with his Trainer and is one of two Pokémon she kept before starting her journey. He is a powerful and fast Pokémon who is often used as land transportation for Yellow. Although a powerful battler, Yellow tended to use her other teammates when fighting.
