During the events in the movie, he was transformed into his Lickilicky due to a combination of Darkrai's Dark Void and Palkia's interference with space. Lickilicky dreamed that it was Alberto and thus Alberto became Lickilicky. Angered by this, Alberto offers a reward to whoever could take down Darkrai. Later on he turns back to his normal form when the effects of Dark Void fade. Alberto appeared again during the ending credits of Arceus and the Jewel of Life. He is piloting his own hot air balloon and still attempting to win Alice's heart. He also made a cameo appearance in I Choose You!, which is set in a timeline separate from the main series. He was seen with his Lickilicky in Alamos Town. (Source: Bulbapedia)
