Laplace

Lapras is a marine reptilian Pokémon that resembles a plesiosaur. It has a blue hide with darker blue spots and a cream-colored underside. It has large brown eyes, a short horn on its forehead, and tightly curled ears. It has a long neck and four flippers. The foremost flippers are larger than the hind. On its back is a heavy, gray shell covered in blunt knobs.

Lapras is a gentle, helpful Pokémon that enjoys ferrying people across bodies of water. In the past, its docility made it an easy target for hunters, and it was driven to near extinction. Recent protection efforts have seen Lapras become overabundant instead, which is now affecting the fish Pokémon numbers in some areas. An intelligent Pokémon, it can understand human speech. As seen in the Pokémon the Series episode Viva Las Lapras (EP115), Lapras has been known to travel in large pods across the seas, spanning both polar and tropical areas. To keep in touch with others of its kind, it sings enchanting melodies. Lapras usually sing when it is in a good mood. In the episode Holiday Hi-Jynx (EP065), it was shown that Lapras can develop psychic abilities such as telepathy. In Alola, Lapras is used as a Ride Pokémon called Lapras Paddle, Alolan natives use Larpas to travel and fish for Pokémon in the water.

Forms

Lapras has a Gigantamax form.

As Gigantamax Lapras, it becomes larger in size and more armored. Its shell resembles a cruise ship or ocarina with four gray and red stripes surrounding it, and it has four spikes on top of its shell with one steel spike resembling a funnel, which has three red clouds surrounding it. The sclera in Lapras' eyes change colors to white, yellow, and blue. A light blue ring of fine thin lines resembling a musical sheet created from ice particles circles around its shell.

5,000 people can ride on the shell of Gigantamax Lapras for a very comfortable ride without any issues. Lapras can use its giant ring to break any icebergs that may prevent it from swimming. According to Oleana, Gigantamax Lapras's shell is not part of its body, as the shell has a logarithmic spiral structure.
