Battling the Bully! (Japanese: ダブルバトル！ピカチュウ・ワルビルVSペンドラー・ガマゲロゲ！！ Double Battle! Pikachu - Krokorok VS Scolipede - Seismitoad!!) is the 17th episode of Pokémon: BW Rival Destinies.
After the events from the last episode, the Sunglasses Krokorok has returned once again to challenge Ash to a battle bent on defeating his rival, Pikachu after he followed them for a long time from Nimbasa Town, Nimbasa City, Driftveil City, and Chargestone Cave. During a rival battle, Krokorok got blasted off while Pikachu is knocked for a loop and is seen rolling into the next town. Pikachu is then found by a little boy name Nick who apparently had no confidence in himself. Ash and co. run into Krokorok again and find Pikachu with Nick. He explains that his friend Glen started something every time always saying the word "Let's Battle!". Meanwhile Glen and Shaun are having a Pokémon battle just for fun which causes Glen to start a fight with Shaun when Blitzle dodged Patrat's Tackle. Can Ash help this budding young trainer how to battle right so he could battle his friends with his Pikachu? And will they receive help from an unexpected source?
The Sunglasses Krokorok attacks Pikachu, who dodges. Iris remembers this Krokorok, who evolved from a Sandile. The Krokorok remembers it followed them from Nimbasa Town through Nimbasa City across Driftveil City and to Chargestone Cave. Ash thinks Krokorok wants to battle Pikachu, who uses Iron Tail, but Krokrok digs. Krokorok attacks, but misses, so uses Stone Edge. Pikachu uses Electro Ball to counter it, but in the collision, a blast sweeps Pikachu and Krokorok away. Pikachu rolls down a slope and falls through a tree into a boy's hands, electrocuting him. The boy thinks Pikachu is a new species of Pokémon, and a pre-evolved form of Zekrom. Pikachu simply thinks the boy should cool down.
The boy asks Pikachu to be his friend. He shows Pikachu to his fellow friends, telling he belongs to his father. One remembers this is actually Pikachu from Kanto, as he was at Saffron City to see it. The other boy proposes a battle, taking the boy's Poké Balls, even if he claims it belongs to his father. The boy leaves with Pikachu, claiming his mother calls him. As the heroes search for Pikachu, they encounter Krokorok, who is looking for him. Krokorok feels something and goes away, so the heroes follow it. The boy asks Pikachu if it is caught or wild, then asks if he knows other moves, besides Thunderbolt. Ash replies he knows Quick Attack, Electro Ball and Iron Tail, making Pikachu glad his trainer came.
The heroes introduce themselves, while the boy is Mick. Mick asks Ash if he can borrow Pikachu, as he wants to defeat his friends, Glenn or Sean. Cilan asks of him to explain why does he need Pikachu. Meanwhile, the two boys have a battle. Patrat uses Tackle, but Blitzle dodges. The other boy is furious, as it was a cowardly move to dodge, thinking he should've attacked back. Mick explains Glenn is the one who challenges to a battle, but he does what he wants. Iris asks if they are too young to battle, but Cilan replies these battles may be just for fun. Mick confirms that and tells when Sean got Patrat and Blitzle, Glenn took Patrat for the battle. Mick wanted to have a battle, but was brushed off to get a Pokémon of his own. Mick wondered where would he get a rare Pokémon and then Pikachu fell down on him.
Ash decides to lend Pikachu. However, Mick is told to train with Pikachu, to know him better and prepare for the battle. Krokorok volunteers to battle, while Ash reminds this is Mick's first battle. Mick orders Thunderbolt, but Pikachu questions that. Still, Pikachu uses Thunderbolt, but does not have an effect on Krokorok. Pikachu uses Quick Attack, hitting Krokorok, but he and Iris remind Mick the battle is not over yet. Pikachu uses Iron Tail, but Krokorok digs, surprising Mick. Krokorok attempts to crunch Pikachu, who uses Iron Tail on it. The attack blows Krokorok's sunglasses off, making it upset, so Krokorok puts them back. It tries to use Crunch, but misses. Ash stops Krokorok and sends Tepig.
Meanwhile, the boy, Glenn, won the matches. Sean is worried, as Patrat and Blitzle are worn out. Glenn wants to battle Mick, even if his story about Pikachu is fake. He orders Sean to get more Pokémon, surprising him. Pikachu uses Quick Attack and clashes with Tepig's Tackle. Cilan stops the match, telling Mick he will be a great trainer one day. Ash and Iris support the claim. Ash advises Mick to battle or catch Pokémon with his heart united. Suddenly, Glenn appears, who scolds Mick and challenges him to a battle. Sean sends the Pokémon his father lended, a Seismitoad and a Scolipede. Glenn tells it will be a double battle, but Sean and Mick remind him Mick has only Pikachu. However, Krokorok volunteers to join the battle.
Cilan decides to stop the match when needed. Pikachu uses Thunderbolt, while Sean orders Seismitoad to intercept, as it has no effect on it. Scolipede uses Poison Tail, but Krokorok uses Stone Edge, though Scolipede dodges. Sean tells it could've used Protect, but Glenn yells at him. Pikachu uses Electro Ball and Krokorok Crunch. Scolipede uses Sludge Bomb to intercept Electro Ball and Seismitoad Drain Punch on Krokorok, but both fail and get hit instead. Cilan cancels the match, declaring Mick the winner. Glenn is mad and goes to hit Mick, but Ash stops him. Sean is also tired of Glenn, as now his father's Pokémon are injured. Cilan gives him some healing food to feed the Pokémon.
Glenn takes the food and feeds the Pokémon himself, admitting this was a fun battle. Glenn apologises to Sean and Mick, the latter thinking they can have another battle someday. Suddenly, Krokorok crunches Pikachu, so Ash pulls it, but gets shocked by Pikachu. Ash thinks it wants to settle things with Pikachu, being its rival. Krokorok starts with Crunch, but gets hit by Quick Attack. Krokorok uses Stone Edge, though Pikachu dodges, but gets encased. Krokorok digs and hits Pikachu. Pikachu uses Thunderbolt on the ground, creating a small hole, causing Krokorok to trip over. Pikachu uses Quick Attack, knocking Krokorok's sunglasses off. Krokorok tries to find them, while Ash explains to the boys he wants to battle fair and square, waiting for Krokrok to get its glasses back.
Krokorok puts them on and uses Crunch, but collides with Pikachu's Iron Tail. Krokorok is defeated, but stands up and leaves, saddened. Ash advises it to come with him, as it has nowhere to go and will have a good time with Ash. Krokorok agrees and lets itself be captured by Ash's Poké Ball. The boys admire Ash's new catch, while the heroes continue the journey.
