Tierno (Japanese: ティエルノ Tierno) is a recurring character who appeared in the Pokémon anime. He is a Pokémon Trainer from Santalune City and a rival of Ash.



In the main series

Tierno and Ash

Tierno debuted in Summer of Discovery! along with Shauna and Trevor, and his Squirtle. He first had a battle against a Trainer's Conkeldurr and won. Later that episode, he battled Ash's Froakie. During his battle with Ash, he revealed that he dreams of forming a dance unit with his Pokémon.

In Foggy Pokémon Orienteering!, Tierno, along with Trevor and Shauna, decided to put the race on hold to help Ash, Serena, and Clemont find Bonnie. The group later encountered a mysterious Pokémon with an X mark on their way back to the camp. Although they arrived too late at the camp to win any points in the race, they declared that helping their friends was totally worth it.

In Battling Into the Hall of Fame!, Shauna, Tierno, and Trevor participated in a Team Battle with Bulbasaur, Squirtle, and Charmander, respectively. Their opponents were their new friends and rivals, Ash, Serena, and Clemont and their respective starter Pokémon. Tierno was the last to defeated in the battle, where his Squirtle was defeated by Ash's Pikachu. He was also seen in a flashback in Showdown at the Shalour Gym!.

Tierno watching a Showcase

In Good Friends, Great Training!, Tierno met Ash during their journey to the Lumiose Gym. He revealed that he already defeated Clembot and earned himself the Voltage Badge. Soon after, Tierno revealed the Pokémon that he caught after the camp: Hitmontop, Ludicolo, Politoed, and Raichu.

Both he and Ash decided to have a Pokémon battle, but it was interrupted by Team Rocket, who captured Ash's Sliggoo and Tierno's Raichu and Wartortle. After the group separated to rescue the Pokémon, Tierno and Bonnie met up with Sliggoo, Raichu, and Wartortle; and decided to go help Ash and Serena. During the confrontation with Team Rocket, Tierno watched as Sliggoo evolved into Goodra and defeated Jessie and James's Pokémon easily. Later, he battled Ash with Wartortle and Raichu, who were defeated by Goodra and Pikachu, respectively.

In Performing with Fiery Charm!, Tierno watched Serena competing in the Dendemille Town Pokémon Showcase along with Shauna and Trevor.

Tierno met Ash and his friends again in Tag Team Battle Inspiration, where he was accompanying Shauna at the Pokémon Showcase that would be held in Anistar City. He revealed that his Wartortle had evolved into a Blastoise and that he had tried to battle at the Gym of the city but lost to the Psychic-type Pokémon from the Gym Leader. Later, Tierno and Ash had a Tag Battle with Serena and Shauna which was eventually called off without any Pokémon getting defeated. He then had a battle again only with Ash, but the winner is not shown. He and Shauna remained in the group, with Tierno that assisted the Pokémon Showcase, which Shauna and Serena participated in, that happened in the next episode alongside Ash, Clemont, and Bonnie.

Tierno made brief appearances in Master Class is in Session! and Performing a Pathway to the Future!, watching the Gloire Showcase Master Class on television along with Trevor.

Tierno and Sawyer

Tierno entered the Lumiose Conference in A League of His Own!, in which he was seen talking to Trevor during the opening reception. In the following episode, he was revealed to have advanced all the way to the quarterfinals, where he was matched against Sawyer.

During the match, Tierno first sent out Ludicolo to battle Sawyer's Aegislash. He commanded Ludicolo to use Rain Dance in order to activate its Swift Swim Ability, but Sawyer's strategy of protecting Aegislash with King's Shield and raising its Attack with Swords Dance proved successful and Ludicolo was knocked out. After that, Tierno decided to use Raichu, and the Mouse Pokémon made quick work of Aegislash with its Dig attack. Sawyer then called out Slurpuff and had it use Attract, infatuating Raichu and prompting Tierno to return it to its Poké Ball.

After that, Tierno called out Blastoise, and when Slurpuff used Attract again, it had no effect. Tierno then asked Blastoise to use Hydro Cannon, rendering the Fairy-type Pokémon unable to battle and forcing Sawyer to sent out his last Pokémon, Sceptile, to the field. Blastoise managed to stand his ground for a while, even resisting a super-effective Leaf Blade, but ended up losing after it got hit by Frenzy Plant. Before he fainted, it used Rain Dance to change the weather and make things easier for his teammate Raichu. When Tierno brought Raichu back into battle and commanded her to use Thunder, he was taken aback as Sceptile Mega Evolved and gained the Lightning Rod Ability, thus being unaffected by Thunder. Tierno then had Raichu use Focus Blast, but Sawyer responded by commanding Mega Sceptile to use Dragon Claw, cutting the Focus Blast in half and knocking Raichu unconscious. As a result, Tierno was eliminated from the competition.

After losing, he decided to remain in Lumiose City to watch the rest of the League together with his friends, which he did up until Down to the Fiery Finish!.

In A Towering Takeover!, Tierno joined the fight against Team Flare. Diantha tasked him, Shauna, Trevor and Sawyer with helping the citizens during the crisis. In Coming Apart at the Dreams!, Rocking Kalos Defenses!, and Forming a More Perfect Union!, he watched the crisis unfold on television in a Pokémon Center. In The First Day of the Rest of Your Life!, Tierno watched the performance that Serena put on to boost morale.

In Till We Compete Again!, Tierno and his group watched some of the wild Pokémon who recently escaped Lumiose City during the Team Flare incident.


Tierno dancing

Much like his game counterpart, Tierno is a dancer. This is also reflected in his party as he tends to catch Pokémon with special dance skills such as Hitmontop and Ludicolo. Despite being a rookie Trainer, he can cope well when battling more experienced opponents thanks to his skills, teaching dance moves to his Pokémon so they can evade attacks with ease. He is then shown to battle strategically, like Sawyer, by Valuable Experience for All!.

Tierno is very friendly and is always encouraging his friends to do their best. He is very supportive of Shauna and often watches her Showcase performances. He has feelings for Serena, which he demonstrates every time they meet. He was responsible for introducing Shauna to Serena.
