Watari

Malachi is a character of the day who appeared in Carrying On!.

He and his grandfather, Denjirō, have multiple Pidgey that act as carrier pigeons. He befriended Ash, Misty, and Brock after they brought back one of their Pidgey, Ken, although he initially accused them of hurting Ken after seeing the bandage on its wings. He is very fond of his grandfather's Pidgey and longs to be in charge of the Pidgey Express business after his grandfather's retirement. The business uses the abilities of the Pidgey in order to send packages and newspapers to the nearby islands without ferry service.

The Pidgey were the target of a Team Rocket heist, literally being plucked from the sky. Ash, Misty, Brock and Malachi then rode on their special flying device, some sort of blimp used by his grandfather for training the Pidgey, to recover all of the Pidgey that Team Rocket had stolen. With the help of Ash's Noctowl, they were able to free the Pidgey and sent Team Rocket blasting off.
