Lucius' Arboliva is one of the fabled Six Heroes. It resided in a forest in the Paldea region but wild fires burned down a large portion of it. It befriended Liko and Roy when it saw it wanted to help heal the forest by replanting. They noticed it had an Ancient Poké Ball around its neck which it returned into and Liko took the ball with her after.

While recovering the pendant from Spinel, it came out of the ball and shone brightly, causing him to back off on his attack and allowed Liko, Roy and Dot to get on it as they floated away from the ship to escape.

During the battle at the Explorers Headquarters, its Tera Type was revealed to be Normal.
