In Baron of Alamos, Rosa's Ditto went off with Alice's Chimchar, breeding with it offscreen. Ditto slips the egg into Rosa's bag.
In The Pokémon Ranch, it is revealed that the egg has hatched off screen and Chimchar sent to Hayley's Ranch. It befriends ranch hand Kidd Summers, constantly being seen by her side. Rosa gives Chimchar to Kidd after seeing this bond.
In Ranch Hand, Chimchar is used in a practice battle against Hayley's Yanma, working to evolve it into Yanmega. It is later used to defeat Reggie's Hippopotas so Kidd could escape.
In Vs. Kidd, Chimchar is Kidd's first choice against Crystal and her Buizel. Chimchar restricts Buizel's movements and prevents him from using any attacks, forcing Crystal to swap him out. Chimchar then battled Happiny, which was able to block Chimchar's attacks and paralyze it. Chimchar is then defeated by one powerful blow.
