Flint's Infernape (Japanese: オーバのゴウカザル Ōba's Goukazaru) is the only known Pokémon owned by Flint in the anime. It is also one of the Pokémon he uses in the games, being his main one in Pokémon Diamond and Pearl.
It was revealed in Flint Sparks the Fire! that Infernape battled by Flint's side since he was a child, when it was a Chimchar. At the time, Sunyshore had a notorious reputation of being full of hoodlums. Having battles day after day, Flint and Chimchar were soon known as the strongest Trainers in all of Sunyshore. When Flint first met Volkner, Chimchar had just taken on two Trainers who sent out Stunky and Jolteon, defeating them with a single Flamethrower. Flint then went on ahead to have a battle with Volkner's Pikachu, which he won. Soon, Volkner challenged them again, which he won, causing a rivalry between the two. Later, the two were shown wondering in a forest at night, during a rain. Encountering a rogue Pokémon poacher and his Houndoom, the two were forced to battle side-by-side with each other for the first time. With Chimchar and Flint getting knocked down by Houndoom's Flamethrower, Volkner is left to continue on his own. Finishing up with Volt Tackle, the poacher is finally chased away. He is later revealed to be the Proprietor, a good friend of both in the present day. Exhausted from the battle, the gang was shown lying on the ground, becoming friends since that day. Having had numerous battles with Volkner day after day, Flint finally decided to leave the city on his journey to becoming stronger.
Infernape debuted in Flint Sparks the Fire!, where it saved Ash from Volkner's Gym's arm machines that had grabbed him as he refused to take a free Badge, which Volkner was now giving away due to loss of passion. Fruitlessly trying to convince him to have the battle, the decision was made for Flint to battle Ash in his place, which Volkner agreed to watch. Taking on Buizel as its first opponent, Buizel started out with Water Gun, which Infernape dodged with a high jump. With Infernape still in the air, Ash ordered Buizel to use Ice Punch, which it easily blocked, having its hands frozen in the process. Taking advantage of the opportunity, Buizel then unleashed Sonic Boom, only to have his hands freed. As its fourth move, Buizel went out charging with Aqua Jet, countered by Infernape's Flare Blitz, which knocked Buizel out of the match. Infernape's next opponent was none other than Infernape. Ash's Infernape started off with a Flame Wheel, which Flint's evaded. It then used a series of Mach Punches, all of which were dodged. Despite a vigorous attempt, Ash's Infernape proved no match either, as it was knocked out by an exceedingly powerful Mach Punch, earning Flint's Infernape two wins in a row. As its last opponent it faced Pikachu. Unlike the last two, it held on well. During the battle, it sparked the flashback of Volkner battling side-by-side with Flint in the woods. After a long battle, Pikachu went charging with Volt Tackle, clashed by Infernape's Thunder Punch. As Pikachu was finally unable to continue, Flint was awarded the win of the match.
Infernape is considered to be quite a humdinger, as it is very well-trained and powerful. This strength was first shown when it was still a Chimchar where it took out a Stunky and Jolteon singlehandedly. The same also applies to Flint's battle with Ash when it easily took out all three of his Pokémon. Infernape is also highly persistent, fighting to the very end with Garchomp in Flint's battle with Cynthia even after having been previously weakened from defeating two of her other Pokémon.

In the games
Infernape is Flint's highest-leveled Pokémon in Diamond and Pearl, and though it isn't in Platinum (that position being given to his Magmortar instead), it is still used in his team when rebattling the Elite Four.
Flint's Infernape Cards listed with a blue background are only legal to use in the current Expanded format. Cards listed with a silver background are legal to use in both the current Standard and Expanded formats.
Infernape is subject to a continuity error: in Flint Sparks the Fire!, it was shown to still be a Chimchar when Flint is an adult, but is a Monferno in Four Roads Diverged in a Pokémon Port!, where Flint is still a child. It's unknown if Monferno's appearance is a mistake or a retcon to their story.
