Smells Like Team Spirit! (Japanese: タッグバトル！ファイナル！！Tag Battle! Final!!) is the 52nd episode of the Diamond & Pearl series, the 518th episode of the Pokémon anime, and the last episode of the tenth season, Pokémon: Diamond and Pearl. It first aired in Japan on October 25, 2007 and in the United States on February 1, 2008.
After a strange victory in the second round of Hearthome City's tag battle tournament, Paul has abandoned his Chimchar and Ash wants Chimchar to join his team instead. Team Rocket wants Chimchar's power for themselves, and they swoop in to steal it. Their hot air balloon getaway flames out when Chimchar toasts their balloon and happily returns to Ash. For the quarterfinals of the tournament, Chimchar will rest and watch Ash and Paul use Staravia and Torterra to battle Brock and his tag battle partner Holly, who are using Croagunk and Farfetch'd.
Unlike Ash and Paul, who are getting along just as badly as ever, Brock and Holly work well as a team. But against a powerhouse Pokémon like Torterra, even Brock and Holly are unable to win. Paul sneers at Ash for celebrating and thinks his Torterra was the only reason they won, but it doesn't matter now. Ash and Paul move on to face Dawn and her partner Conway in the final round. And for this battle, Ash chooses Chimchar and Paul chooses Elekid to battle against Dawn's Buizel and Conway's Heracross.
Dawn and Conway are good partners, too: they know how to work together and synchronize attack and defense. However, Conway's strategies didn't anticipate that Paul's Elekid would evolve into Electabuzz in the middle of the match! Buizel and Heracross do their best, but Electabuzz's power and Chimchar's Fire-type attacks win the day. Of course, now that he's evolved his Elekid, Paul couldn't care less about victory or the Soothe Bell prize. But Ash believes Paul's Chimchar will be a great addition to his team, and he's looking forward to the next Gym battle in Veilstone City!
Ash is kneeling down to the newly-released Chimchar. Impressed by the way Chimchar gives it its all, Ash tries to convince Chimchar to be on his team. However, a disgusted Paul tells them that as far as he's concerned they are a perfect match; a pathetic Pokémon for a pathetic Trainer. Ash tells Chimchar to ignore his former Trainer, and offers the chance to prove him wrong. Before Chimchar can accept, our heroes are attacked by Bullet Seed and Pin Missile. Chimchar is stolen by Team Rocket, the attackers. After finishing their motto, James tells Carnivine and Cacnea to use attack again as they attempt to escape. However, Ash is intent on rescuing Chimchar, and Chimchar takes action, using Flamethrower to destroy Team Rocket's balloon, but plummets to the ground. Ash manages to catch Chimchar just in time, and with the day saved, asks again if Chimchar would like to be on his team. Chimchar happily agrees, so Ash throws a Poké Ball into the air. Chimchar happily jumps up and smacks the button, and without any struggle, Ash catches Chimchar. Later that night, Ash contacts Professor Oak to tell him about what has been going on. After complimenting Chimchar, Oak states that Ash and Paul need to work together to win as much as Ash would with his Pokémon.
The next morning, the battles continue in the Tag Battle Competition. Dawn and Conway have already won their semi-final match, so the next match-up is Ash and Paul versus Brock and Holly. They each send out their respective Pokémon: Staravia, Torterra, Croagunk, and Farfetch'd. Ash commands Staravia to use Aerial Ace, Brock tells Croagunk to use Poison Jab, Holly's Farfetch'd uses Air Slash and Paul's Torterra uses Hyper Beam. All of the attacks are launched, but only Hyper Beam makes its way through, hitting Farfetch'd, as well as Staravia. However, Farfetch'd is knocked out in an instant. Holly apologizes for letting Brock down, but he tells her not to worry and tells Croagunk to use Brick Break. Ash tells Staravia once more to use Aerial Ace, trying to catch Croagunk off-guard. However, Croagunk slides under the immobilized Torterra, causing Staravia to miss and have to stop its attack. Croagunk jumps out from behind Torterra, landing a hit with Brick Break on Torterra's head. However, before Croagunk can use Poison Jab, Torterra is able to move again. Croagunk jumps backwards onto the tree on its back, and Torterra uses Leaf Storm, knocking Croagunk out, and giving victory to Ash and Paul. Ash congratulates Staravia on a good job, only for Paul to angrily comment that Staravia contributed nothing to the battle.
Returning to the Pokémon Center after the match, Nurse Joy tells Brock that Holly was so upset about losing that she left to go and train. Devastated by losing the one woman who liked him, Brock tells Ash to go and win the match. Finally, the final battle of Dawn and Conway versus Ash and Paul begins. Ash sends out Chimchar, Paul uses Elekid, and Conway and Dawn call out Heracross and Buizel. Ash's first attack is Flamethrower, followed by Elekid using Thunder. However, Buizel is able to counterattack Flamethrower with Aqua Jet, which in turn is countered Elekid's Thunder. Conway backs Buizel up by telling Heracross to use Revenge. Heracross gets in to take the Thunder attack, and uses the power of Revenge to attack Elekid. Next, Chimchar uses Dig as Dawn calls for Buizel to use Aqua Jet again. Elekid uses Protect, but at the last minute, Buizel heads skywards and Conway tells Heracross to use Feint to break the Protect, taking Paul off-guard. Buizel then uses Water Gun, hitting Elekid, but Chimchar finally hits Buizel with Dig.
Buizel counters with Aqua Jet, again hitting Chimchar. Chimchar quickly recovers and uses Flamethrower on Heracross, but Buizel jumps in front of Heracross and uses Water Gun. The attacks collide, causing an explosion. Elekid jumps through the smoke and uses Thunder Punch, while Heracross counters with Megahorn. Another explosion is created, sending Elekid flying backwards. Suddenly, Elekid begins to evolve into Electabuzz, shocking everyone. The newly evolved Electabuzz then begins to charge up its Thunder. In response, Conway tells Heracross to use Megahorn and Buizel uses Water Gun. Ash tells Chimchar to dodge Water Gun and to use Flamethrower on Heracross, while Electabuzz uses Thunder on Buizel. All the attacks collide, causing an explosion. Just when it seems like the battle is over, Buizel and Heracross are seen still standing once the smoke clears. However, Buizel gives his opponents a final smirk before they both fall to the ground, knocked out. Taking the win, Ash congratulates Chimchar, although Paul remarks that if Chimchar was any good, Heracross would never have got back up. However, Ash does not care what Paul thinks; as far as he is concerned, Chimchar did a fantastic job.
At the awards ceremony, Enta gets on stage to give Ash and Paul their Soothe Bells. Everyone applauds Ash and Paul, while Conway muses that for a tournament that was supposed to emphasize teamwork between Trainers, it was the team that co-operated the least that ended up winning. That evening, at the Pokémon Center, Ash and his friends discuss the battles that happened. Although Dawn is discouraged about losing, she promises to win her next Contest. Suddenly, Paul passes by, tossing his Soothe Bell at Ash, saying that he does not need it. Brock notes that for Paul, the tournament was simply an opportunity to power up his Pokémon, and as far as he's concerned, Elekid evolving was the only good thing to come out of the competition. Conway then suggests to Ash that he could next head for Veilstone City as it has a Gym, seeing as the Hearthome Gym is currently closed. The gang agrees that it is a good idea and therefore, with a new Pokémon on his team, Ash prepares to head to Veilstone City and hopefully earn his third Gym Badge.
