Lapras are a very large type of Water/Ice that resemble a plesiosaur. Its skin is mainly a light blue with a cream/white underside. It has a very long neck with a rounded head. Its ears are shaped like a spiral and it has a small horn on its forehead. Having no legs, it instead has four flippers for easy mobility in the water. Lapras also have a large, gray shell on their back with "knobs" covering it.
Lapras can have the ability Water Absorb or the ability Shell Armor. With Water Absorb, Lapras can heal 1/4 of its max HP if it is hit with a Water-type attack. With the ability Shell Armor, Lapras can block any Critical Hits.
In addition to this, Lapras can ferry people on its back and also sing people to sleep. Some Lapras can use Telepathy to communicate with humans as well.
Lapras' next major appearance was in the episode The Lost Lapras, where Ash saved a baby Lapras from a group of thugs and Team Rocket. He would go on to use this Lapras to ferry him around the Orange Islands. He later found its family and returned the baby Lapras. And there is an appearance of Lapras in the Sinnoh region when Dawn mentions how beautiful it is.
