Maclachi's grandfather's Pidgey are normal/flying-type Pokémon owned by Malachi's grandfather.
Malachi's grandfather owned a Carrier Pidgey Company, in which Pidgey delivered mail to the citizens. He had to treat them and show them the way so they can act effectively. One day, the Pidgey were missing, so Malachi went with heroes to uncover the truth. Team Rocket captured them, so Malachi freed them, then the Pidgey pecked the balloon away. Once done, the Pidgey delivered medicine to Nurse Joy to an island.
