Fissure

Fissure was first introduced in Generation 1. In the pokédex, the first Pokémon recorded with this move is Diglett. Fissure is a one-hit KO move. Like other one-hit KO moves, the foe must be a lower level than you in order to have a chance to hit(a small chance at that.) If the foe is a higher level than you, it will fail. It is a ground type move and can be used by many Pokémon such as: Groudon, Diglett, Dugtrio, Camerupt, Trapinch, Barboach, Whiscash, Wormadam (Trash Cloak), Hippopotas, and Hippowdon by leveling up. Vibrava and Flygon can learn it if Trapinch has already learned the move when you decide to make it evolve. Lapras, Snorlax, Swinub, Piloswine, Mamoswine, Phanpy, Donphan, Wailmer, Wailord, Torkoal, Spheal, Sealeo, Walrein, Shieldon, Bastiodon, Shellos, and Gastrodon can learn fissure by breeding.
