After being knocked to the brink of fainting in a battle against Barry's Empoleon, Monferno went berserk with its Blaze Ability and unleashed its full power against Team Rocket. While protecting the Pokémon, it evolved into Infernape. Infernape has many powerful attacks at its disposal such as Flame Wheel and Flare Blitz so it's set to be the powerhouse behind Ash's team. It was later used in a battle against Flint's Infernape, but lost due to its lack of experience. Chimchar → Monferno → Infernape
