Lapras has gained notoriety from being one of the companions of the anime’s main character, Ash Ketchum. Additionally, the character was one of the rarer Pokémon in the original series of games, making this water/ice-type all the more unique and desirable. Lapras may not have any evolutions, but that has not stopped this Pokémon from being one of the most seldom encountered in all of Pokémon Go.
Coming across a wild Lapras is almost unheard of for most gamers, but it is, of course, hatchable using a 10km egg. There are 17 possible Pokémon that could be hatched from an egg, so this still leaves players with a fairly slim chance of actually adding the rare Pokémon to their respective teams.
There are a few gyms out there sporting this uncommon beast, but they are most likely the lucky few who were fortunate enough to hatch a Lapras from a 10km egg.
