Pokemon 731

Pokemon 731 (AKA ghost, dex #731, missingo. form 3) is a pokemon who can be encountered in Pokemon tower, which is south of Lavender town.

Pokemon 731 appears when you encounter a pokemon in Pokemon Tower and you dont have Silph Scope.

When encountered, it knows the moves "Leer", "Mean look" and "Beat up", however, it is uncatchable and will dodge pokeballs.

When encountered while a Silph Scope is on hand, Pokemon 731 instantly turns to a Marowak and is catchable.

You can catch it if you do the Missingo. glitch while the letter Y is in the sixth slot of your name, when this happens, the pokemon is named "Missingo." and only knows the move "Water gun".

When caught, it will instantly transform into a normal Rhydon.

Due to Pokemon 731's mysterious nature, many Creepypasta stories sorrounding it have been made.
