In Rising from the Ruins!, Lycanroc left its Trainer to go and find Rockruff after hearing its howling. It eventually met up with Olivia's Lycanroc and took Rockruff to the Ruins of Life. There, they encountered Tapu Lele, who attacked them. After a quick fight it uses Draining Kiss on both Lycanroc and transfers the energy to Rockruff. Lycanroc later watched as Rockruff evolved into Dusk Form Lycanroc. Afterwards, Lycanroc returned to Gladion.
After accompanying Gladion when he confronted Ash in Mission: Total Recall!, they returned to their hotel room. They were confronted by Faba, who demanded that Gladion return Type: Null, which Gladion refused to do. Alongside Umbreon, Lycanroc battled Faba's Hypno and Alakazam, only to be taken out of the fight by Hypno's Hypnosis.
In Rescuing the Unwilling!, Gladion used Lycanroc and Umbreon to fight Lusamine's Absol, which was controlled by Nihilego, to allow Ash to save Lusamine. They were eventually trapped by Absol's Mean Look. In 10,000,000 Reasons to Fight!, Lycanroc was released from the Mean Look after Silvally used Multi-Attack on Absol. Soon afterwards, Gladion and Lycanroc used Continental Crush on Absol. Although Absol appeared to have been defeated by this move, Nihilego made it get back up and continue battling. Gladion told Lycanroc and Umbreon to take care of Absol while he rode off on Silvally to get to his mother.
In The Final Four!, Gladion sent out Lycanroc as his first Pokémon in his semifinals battle with Kiawe. First, Lycanroc went up against Marowak, whom it managed to defeat with relative ease, despite taking a hit from a super-effective Iron Head. Next, Lycanroc faced Turtonator. It dealt heavy damage on him with Outrage while also enduring a hit from Shell Trap. However, Turtonator was able to endure Lycanroc's attacks and ended up learning Focus Blast, which he used to defeat Lycanroc.
In Enter the Champion!, Gladion used Lycanroc as his final Pokémon against Ash and his own Lycanroc during the finals of the Manalo Conference. Ash's Lycanroc's attempts to get close to Gladion's Lycanroc were repeatedly intercepted by Counter and Stone Edge. After powering itself up with Swords Dance, Gladion's Lycanroc got close enough to attack with Outrage, only to get confused and bite its left arm. Ash had his Lycanroc take this opportunity to attack, only for Gladion's Lycanroc to retaliate with Counter, revealing it bit itself to snap itself out of the confusion. Ash had his Lycanroc rush in with Accelerock, hoping to land one final blow. Gladion had his Lycanroc intercept with one more Counter, but just as it connected, Ash had his Lycanroc use Counter as well. This sent Gladion's Lycanroc flying into the wall, knocking it out and making Ash the winner of the championship.
In Z-Move Showdown!, after a trio of Guzzlord invaded the Manalo Conference, Gladion and Lycanroc combined their Z-Move with those of the other Trainers, knocking the second ShinyGuzzlord back into Ultra Space.
Lycanroc appeared in The Homecoming Crown!, taking a picture with Gladion, his family, and their Pokémon after reuniting with Mohn. In Helping the Hometown Hero!, it trained alongside the rest of Gladion's team to prepare for Gladion's upcoming battle with Ash.
Personality and characteristics
Lycanroc is a caring Pokémon, as seen in Rising from the Ruins!, where it left its Trainer of its own accord to go to the aid of Ash's Rockruff and defended it against Tapu Lele. It is also a powerful Pokémon, being able to overwhelm opponents with its strength. It also has a strong willpower, able to control itself even while under the affect of Outrage.
