Ash's Krookodile evolved from Ash's Krokorok during a battle against Iris in the semi-finals round of the Pokémon World Tournament Junior Cup.

Isshu League Tournament

Ash's Krookodile participated in the Isshu League Higaki Tournament. It was matched up against Stephan's Liepard in the first match up of the third round battle. The two had a sudden clash between Shadow Claw and Dragon Claw and their strength appeared to be even. They then used Shadow Ball and Stone Edge which collided in mid-air and those attacks also proved to be even. The match up proved to be a very direct battle which was expected from Ash Ketchum and Stephan. The match up began to change when Stephan's Liepard began to use Double Team in combination with its other moves to confuse Ash's Krookodile and finally land hits. The match up ended though with two consecutive Shadow Claw and Dragon Claw attacks against each other with Ash's Krookodile being the one able to endure the attacks best and win the match up.

The final match up of the third round ended up being Stephan's Sawk vs Ash's Krookodile, both of which were very injured from the previous battles. Both of them did their best to muster up their reserve strength but in the end a surprise move of Aerial Ace by Ash's Krookodile was super effective against Stephan's Sawk and it knocked it out to give Ash Ketchum the victory while eliminating Stephan from the tournament. Stephan realized after the battle that the reason that Ash Ketchum withdrew Waruvial after the first battle was because Ash Ketchum knew that Stephan would definitely send out Dageki, so he didn't reveal that it knew Aerial Ace and saved until the end.
