Ash's Chimchar evolves into Monferno and learns Mach Punch.
This is the third time that one of Ash's Pokémon has evolved against Paul, with Chimchar evolving into Monferno. The first two were Turtwig evolving into Grotle, and Staravia evolving into Staraptor.
This is the 600th episode of the anime, if Rougela's Christmas (1998) and Iwark as a Bivouac (1998) are counted.
All three of the Pokémon Ash used in his battle against Fantina in Yosuga Gym Match! Vs Melissa!! (2008) used Counter Shield in this episode.
Paul wins the Full Battle against Ash.
