Juan

Milotic debuted in The Great Eight Fate, where it was first used in a water exhibition. It also won in a battle against Team Rocket. Milotic is Juan's strongest and most experienced Pokémon, having helped Juan in his career as a Coordinator by winning many Pokémon Contests years ago. With the help of Milotic, Juan was able to win the Grand Festival, earning the Ribbon Cup and the title of Top Coordinator. Nowadays, Milotic uses all of its experience against challengers who come to the Sootopolis Gym.

Juan used Milotic as his final Pokémon in the Gym battle against Ash. With its elegant grace and power, Milotic was able to gain the upper hand against Ash. It defeated Ash's Swellow with Hydro Pump and Twister, then put up a good fight against Pikachu thanks to its ability to Recover from Electric attacks. It was also able to draw in Pikachu's Thunder with Iron Tail. However, Pikachu pulled Milotic below the water and used Thunder to defeat it, thus earning Ash the Rain Badge.

Milotic's known moves are Twister, Hydro Pump, Iron Tail, and Recover.

Luvdisc first appeared in The Great Eight Fate!, where it put on a dazzling performance with Juan's other Pokémon. It was later captured by Team Rocket, but was freed.

During the second round of his battle with Ash, Juan chose Luvdisc against Grovyle. Luvdisc started out with Water Pulse, but Grovyle dodged in time and countered with Leaf Blade. Luvdisc, however, was fast enough to dodge that attack and used Sweet Kiss, confusing Grovyle. Grovyle hit itself in its confusion, and Luvdisc finished it off with Water Gun, which resulted in a loss for Grovyle despite the type advantage. Ash switched back to Corphish. The two Pokémon kept dodging each other's attacks until Luvdisc dived underwater and Ash ordered Corphish to hit the water with Crabhammer. Corphish's attack sprayed the battlefield with water, simulating heavy rain, which activated Luvdisc's Ability, Swift Swim, allowing it to move even faster than before. Eventually, Corphish managed to hit Luvdisc with another Crabhammer, taking it out of the battle.

Luvdisc's known moves are Water Pulse, Sweet Kiss, and Water Gun, and its Ability is Swift Swim.

Sealeo made a cameo during its first appearance in Team Rocket's electric net, but was eventually freed.

In the next episode, Sealeo was one of two Pokémon Juan used in the first round of his battle with Ash. Sealeo used Blizzard on Pikachu and Snorunt, but Snorunt countered it with Icy Wind. It then tried to hit Pikachu with Aurora Beam, but Pikachu dodged. When Ash switched Snorunt for Corphish and attacked with Bubble Beam, Sealeo dived into the water and tried hitting Pikachu again, but once again, Pikachu dodged. After Sealeo was left alone against both of Ash's Pokémon, it used Ice Ball repeatedly and almost won the battle, but was eventually taken down by Corphish's Crabhammer.

Sealeo's known moves are Blizzard, Aurora Beam, and Ice Ball.

Seaking battled alongside Sealeo in the Double Battle against Pikachu and Snorunt. It used Horn Drill to reflect Pikachu's Electric attacks at Snorunt. When Ash's Pokémon were attempting to attack from up close, Seaking hit Snorunt with Hyper Beam, forcing Ash to switch Snorunt for Corphish. Seaking then dived and used Horn Attack, but Corphish caught it by the horn. Seaking followed up with Horn Drill, damaging Corphish, but was then hit by Pikachu's Iron Tail and fainted.

Seaking's known moves are Horn Drill, Hyper Beam, and Horn Attack.

The fourth Pokémon Juan used against Ash was Whiscash, who easily defeated Ash's Corphish with Surf and Rock Smash. Ash then chose Swellow, but Whiscash grabbed it and used Tickle followed by Hyper Beam. Juan thought he won the round, but Swellow recovered and used Aerial Ace, even after Whiscash dived underwater. After missing another Hyper Beam and getting hit by another Aerial Ace, Whiscash was unable to battle.
