Pokémon the Series: Black & White

As a wild Pokémon
Sandile commanding the other Sandile into action

Krookodile debuted in A Sandile Gusher of Change! as a wild Sandile, where he was revealed to be the leader of a group of other Sandile who lived near a local spa resort. He and the group caused trouble at the spa resort on Route 1 to get the owners' attention. He was trying to save the other Pokémon in the area because he knew that a geyser would soon erupt. With the help of Ash, Iris, and the son of the spa resort owner, Dan, Sandile was able to save the Pokémon. In the end, Sandile was shown to have gained respect for Ash and, as such, began to follow him.

In Here Comes the Trubbish Squad!, Sandile wanted to battle Pikachu. He randomly attacked with Stone Edge despite there being small children close by. He was sent blasting off by a wild Trubbish's Sludge Bomb and Pikachu's Iron Tail.

In Dancing With the Ducklett Trio!, Sandile separated Ash from the group to battle Pikachu again. However, a wild Ducklett stole his sunglasses and stopped the battle. Sandile was deeply saddened without his sunglasses, losing his usual confidence and becoming cowardly. With Ash and Pikachu's help, he defeated the Ducklett and reclaimed his sunglasses. Later, after being healed at the Pokémon Center, Sandile finally got the battle he wanted with Pikachu. Sandile dominated the battle and eventually evolved into Krokorok. Pikachu soon gained the upper hand, however, and sent Krokorok blasting off when his Electro Ball attack collided with Krokorok's Stone Edge, causing the stones to hit Krokorok and send him flying.

Krokorok battling Pikachu

After a long absence, Krokorok returned at the end of Explorers of the Hero's Ruin! with the same goal of defeating Pikachu in battle. In the following episode, he battled against Pikachu and ended up causing the two of them to go flying. Ash and his friends later found him before helping them locate Pikachu. It was revealed that Krokorok had followed them through various locations, including Nimbasa Town and Nimbasa City, to have a rematch with Pikachu. He also followed them through Chargestone Cave, where he was shown to be the cause of a pen being stuck in the Klinklang in Evolution Exchange Excitement!. Krokorok later allowed Ash to use him to help Mick learn to battle. He eventually teamed up with Pikachu under Mick's command in a Double Battle against Sean's father's Seismitoad and Scolipede, where the duo eventually won. Krokorok then got the chance to battle Pikachu as he had wanted for so long, and after a hard-fought battle, Pikachu emerged victorious. Krokorok was depressed by the loss and began to leave when Ash invited him to join their team. Surprised but delighted by the offer, Krokorok happily agreed and was caught by Ash in a Poké Ball.

With Ash

In An Amazing Aerial Battle!, Ash used Krokorok in his Gym battle against Skyla. He faced her Swoobat, who she had previously predicted would beat him. Krokorok struggled in the battle, having all his moves evaded while narrowly escaping Swoobat's. Krokorok finally landed a single hit with Stone Edge before Swoobat countered it with a powerful Air Cutter, defeating him.

Krokorok training with Ash under Brycen

In Guarding the Guardian of the Mountain!, Ash chose Krokorok for some special training with Brycen and his Beartic. When the training began, Krokorok and Ash had problems following Brycen and Beartic's techniques, especially when they had to jump down a waterfall, which Krokorok refused to due to his fear of water. Later, Krokorok was used in a battle against Pokémon poacher Rizzo in an attempt to free the guardian, Volcarona, of the mountain they were training on. He battled a Jellicent and was hit by a super-effective Hydro Pump after missing with Crunch. Regardless, Krokorok got back up and landed several hits on his opponent with Stone Edge before using Crunch again, though it was deflected. Krokorok attempted Crunch from a different angle, only to receive a painful hit from Jellicent's Hex attack. Persevering, Krokorok avoided his opponent's Confuse Ray with Dig and finally landed an effective hit with Crunch on the Ghost-type Pokémon. Krokorok tried another Crunch, only to be stopped by Hex again, though he dodged Confuse Ray with Dig and hit Jellicent with Crunch, as he did before. Rizzo then brought out a second, female, Jellicent, which hit Krokorok with her Confuse Ray. Krokorok was then hit by a double Hydro Pump and sent into Rizzo's cage with Volcarona. Brycen and Beartic eventually rescued him and the Sun Pokémon.

In Caution: Icy Battle Conditions!, Krokorok was pumped up for the upcoming Gym battle and accompanied Ash to the Gym outside of his Poké Ball. He started off battling Brycen's Vanillish and began with a Crunch but was halted by Vanillish's Astonish. After the collision of Stone Edge and Icicle Spear, Vanillish launched a Blizzard that froze Krokorok while he was attempting to dodge with Dig. Ash recalled Krokorok after a Mirror Shot thawed him. He was later sent out to battle against Beartic. Krokorok's Stone Edge was deflected by Beartic's defensive Icicle Crash, causing the Stone Edge to hit Krokorok. Krokorok's Crunch was countered by Ice Punch freezing his mouth. Krokorok narrowly escaped a super-effective Brine by using his tail to jump onto an ice pillar; climbing it and shaking off the ice before finally landing a direct hit with a super-effective Stone Edge while mid-air. Krokorok was then able to land a direct hit with Dig; however, this allowed Beartic to grab him by the tail and throw him across the battlefield into a large mound of ice. Seeing the broken ice made Ash think of Stone Edge and gave him an idea. Ash ordered a Stone Edge attack that was deflected again by Icicle Crash. However, Krokorok jumped up and grabbed two stones, charging down from the air with the Stone Edge in hand to meet Beartic's Aerial Ace attack. After the collision, Beartic was knocked out, leaving Krokorok the victor and winning Ash the Freeze Badge.

Krokorok battling Iris's Dragonite

In Ash, Iris, and Trip: Then There Were Three!, Ash used Krokorok during his battle against Iris's Dragonite in the semi-final round of the Pokémon World Tournament Junior Cup. Krokorok's attacks were initially dodged, and he was hit by Flamethrower. Krokorok managed to dodge many of Dragonite's attacks with Dig, though he still took some hits and clamped down on his opponent's tail with Crunch. He was thrown off but still managed to hit Dragonite with Stone Edge before missing with Crunch and getting hit by Flamethrower. Krokorok tried another Crunch attack but was rapidly hit by two Flamethrower attacks and an Ice Beam. To everyone's surprise, Krokorok evolved into Krookodile and hit his opponent with a newly learned Dragon Claw. Dragonite began to thrash about, launching its attacks all over the place in temper, but Ash ordered Krookodile to attack anyway. Krookodile finally won the match by easily dodging Dragonite's Dragon Rush with Dig and landing a direct hit with Stone Edge.

In Meloetta and the Undersea Temple!, Ash sent Krookodile out to battle Meloetta after Oshawott had refused to battle it, not wanting to hurt the Pokémon he loved. Meloetta started the battle with Hyper Voice, which was strong enough to push Krookodile back. The Intimidation Pokémon then attacked with Stone Edge, which was, however, blocked by Meloetta's Close Combat, much to Krookodile's astonishment and annoyance. Ash then told Krookodile to use Dragon Claw, but before the attack could hit, the battle was interrupted by Ridley's Golurk, as he thought they were trying to hurt Meloetta. The Melody Pokémon was, however, able to convince him that Ash and his friends were harmless.

Krookodile and Ash

In Strong Strategy Steals the Show!, Ash chose Krookodile as his first Pokémon in his Vertress Conference battle against Stephan and his Liepard. The battle started with a clash of Liepard's Shadow Claw and Krookodile's Dragon Claw, after which the two continued to match each other in power and skill. To prevent Krookodile from attacking Liepard after resurfacing during a Dig attack, Stephan had Liepard use Double Team. Thanks to this, Liepard was able to strike Krookodile with Shadow Claw and Shadow Ball in succession before Krookodile finally managed to strike Liepard with a Stone Edge. However, Liepard quickly hid amongst its copies again with another Double Team, and successfully hit Krookodile with a Hyper Beam, despite his attempt at dodging with Dig. Ash told Krookodile to use Dragon Claw once again, while Stephan had Liepard use Shadow Claw. As this sideswipe of moves didn't cause either of the weakened Pokémon to fall, the same clash was repeated, and this time, Liepard was defeated. When Stephan sent out Zebstrika, Ash recalled Krookodile. The Intimidation Pokémon was later sent out to battle Stephan's final Pokémon: Sawk. After a fierce exchange of Dragon Claw and Close Combat, when Sawk prepared to strike back with Karate Chop, Ash surprised Stephan by telling his Pokémon to use a new move: Aerial Ace. The super-effective move on the Fighting-type Pokémon did its work, and Sawk was defeated, winning the match for Ash and eliminating Stephan from the tournament.

In Team Plasma and the Awakening Ceremony!, Krookodile was sent out alongside the rest of Ash's team to help Ash and N dig up to the surface of the White Ruins after they had fallen into a pit. He used Dig to help Charizard and the others get through the earth that Oshawott had softened with Hydro Pump. While battling Team Plasma, Krookodile cleverly used Dig to fire tons of rubble toward the opposing Pokémon to weaken them. However, when Colress turned his mind-controlling machine on them, Krookodile was quickly recalled to his Poké Ball along with Ash's other Pokémon. In What Lies Beyond Truth and Ideals!, Krookodile later helped trap Ghetsis, Colress, Aldith and Barret with Stone Edge so they wouldn't be able to escape and could be arrested by Looker.

Decolore Islands

Krookodile remained on Ash's team as he began his travels in the Decolore Islands. Even so, he was eventually sent to Professor Oak's Laboratory in Butterfree and Me so that Ash could receive Leavanny to assist with a Caterpie. He was reunited with Ash and the entire Unova team at the lab in The Dream Continues!. He joined the others in a group attack on Team Rocket with his Stone Edge to send them blasting off for the last time in Pokémon the Series: Black & White. Krookodile later posed in a group photo with the rest of Ash's Pokémon. Then, he was left at the lab when Ash set off for the Kalos region.

Pokémon Journeys: The Series

Krookodile with Snorlax and Totodile

In Advice to Goh!, Krookodile reunited with Ash during his visit to Professor Oak's Laboratory with Goh.

Krookodile, along with the rest of Ash's Pokémon at the lab, reunited with Ash in Friends, Rivals, Lend Me Your Spirit!. During the visit, he was seen relaxing with Snorlax and Totodile and later watched the battle between Ash and Paul. Before Ash left, he posed with the rest of Ash's Pokémon in a group photo with him.

From Battling as Hard as Stone! onwards, Krookodile watched Ash's Masters Eight Tournament matches against Steven, Cynthia, and Leon. In Partners in Time!, Krookodile appeared as a vision to Pikachu during his battle against Leon's Charizard.

In Heroes Unite!, Krookodile, along with the rest of the Pokémon at the lab, welcomed Ash back to Pallet Town after his victory over Leon.

In The Rainbow and the Pokémon Master!, Krookodile assisted Ash in looking for a missing Charmander around Oak's lab, but to no avail.

Personality and characteristics

Krokorok's lack of confidence without his sunglasses

As a Sandile, Krookodile had a very caring side, trying to save a group of wild Pokémon after sensing an imminent geyser eruption in A Sandile Gusher of Change!. He's also highly competitive, confident, and proud of his abilities, even to go so far as to follow Ash throughout his entire journey, up until Battling the Bully!, wanting to battle Pikachu, who he sees as a rival. However, it was revealed in Dancing With the Ducklett Trio that whenever he lost his trademark sunglasses, he would immediately become timid and cry until he got them back, scrambling to find them.

Despite his intelligence and compassion, he could be reckless and cause problems he never meant to; for instance, throwing Cedric Juniper's pen away and getting it stuck in a Klinklang when he was not looking. He also tends to react suddenly, often attacking without warning. Krookodile seems to prefer to help those that need him, though, such as when Mick was battling with Ash's Pikachu and needed a second Pokémon to battle against Sean and Glenn. After he became a Krookodile, he became significantly faster and stronger, being able to defeat powerful opponents like Iris's Dragonite and Stephan's Sawk while at a disadvantage. It is unknown whether he is still timid without his sunglasses, as he never lost them after being captured.

Description: A variant of Stone Edge used by Ash's Krokorok when he grabbed two of the Stone Edge shards and used them as daggers. Krokorok used this technique to defeat Brycen's Beartic during their Gym battle. It was inspired by Bianca's Emboar's use of the move Fling to catch a Stone Edge attack from Trip's Conkeldurr during A Clubsplosion of Excitement!.

  • It took 62 episodes from Krokorok's debut to his capture, longer than any other Pokémon in the anime.
  • Krookodile is Ash's second Pokémon which evolved on-screen before his capture. The first one was Primeape. Unlike Primeape, however, Krookodile's evolution and capture were in two separate episodes.
  • As a Sandile, he was the first recurring wild Pokémon to evolve onscreen.
  • Krookodile is the first Dark-type Pokémon belonging to a main character to have evolved on-screen.
  • Krokorok was the only Dark-type Pokémon Ash has owned that was caught, seeing how Scraggy hatched from an Egg, while both Greninja and Incineroar gained the type upon evolving.
  • In BW030, Professor Oak's Pokémon Live Caster showed a clip that revealed that Krokorok was to appear in at least one of the two unaired episodes. The script of these episodes, which surfaced in May 2023, reveals that Krokorok would have appeared in the first one of these two episodes, providing a distraction to allow Ash and his friends to board Team Rocket's helicopter in the Desert Resort.
