Olivia's Lycanroc (Japanese: ライチのルガルガンLychee's Lugarugan) is a Pokémon owned by Olivia in the anime, games, and manga. In the anime, Olivia owns a Midday Form Lycanroc, while in the games and in Pokémon Adventures, she owns a Midnight Form Lycanroc.
Lycanroc debuted in The Island Whisperer! to help Kiawe's Charizard when it was struggling to deal with an out of control Tauros. Lycanroc quickly calms the Wild Bull Pokémon down. It is later seen getting acquainted with Ash's Rockruff. Afterwards, it helps fend off a wildBruxish.
In Trials and Determinations!, Lycanroc was used during Olivia's grand trial battle against Ash, where it teamed up with Probopass to battle Ash's Rockruff and Rowlet. Despite proving to be a formidable opponent with its strength and speed, Lycanroc was eventually defeated by Rockruff's Rock Throw.
In Rising from the Ruins!, after hearing about Rockruff's disappearance, Lycanroc left its Trainer to go and find him. It eventually met up with Gladion's Lycanroc and took Rockruff to the Ruins of Life, where they encountered Tapu Lele, who attacked them. Lycanroc later watched as Rockruff evolved into a Dusk FormLycanroc. Afterwards, Lycanroc went back to Olivia.
In Securing the Future!, Lycanroc joined the rest of Alola in showering Necrozma with light so it could return to its normal form. After it returned to its normal form, it and Olivia used their Z-Move to shower Necrozma in a blinding amount of light.
In Heart of Fire! Heart of Stone!, Olivia used Lycanroc in her battle against Brock. It went up against Sudowoodo, but the battle was interrupted when Team Rocket attempted to steal the Pokémon. Lycanroc was able to stop them when Brock and Olivia teamed up, allowing Lycanroc to use a heart-shaped Continental Crush against them.
Lycanroc is depicted as a caring Pokémon. For example, in Rising from the Ruins!, it left its Trainer on its own accord to help Ash's Rockruff and defend it from Tapu Lele.
Olivia's Lycanroc appears alongside Olivia as a sync pair.
