Lapras made a cameo appearance in Ash Ketchum vs Charles Darwin.
Information on the cameo
Lapras is a dual Water/Ice-type Pokémon from the Pokémon series. Its species is the Transport Pokémon. It is most often used by many trainers to cross large expanses of water. Ash Ketchum previously owned one throughout the Orange Archipelago arc, where he used it to travel across the sea between islands, before releasing it afterwards.
Appearance in the rap battle
Lapras makes an appearance at the end of Ash Ketchum's second verse. Ketchum rides off on the back of the Pokémon as he says the line, "Set sail and Galápago-suck on these!"
