Omanyte, a Rock/Water type Pokmon, is a Generation I fossil Pokmon obtainable in specific Pokmon games. In the context of the second generation titles, it is not directly found within the game world. Instead, access to this Pokmon requires a specific procedure involving previous entries in the franchise. The original games, Pokmon Red, Blue, and Yellow, are where Omanyte is obtainable through fossil resurrection.
The significance of acquiring this fossil Pokmon in subsequent generations lies in completing the Pokdex, a comprehensive index of all known Pokmon species. Furthermore, incorporating Omanyte and its evolution, Omastar, into a team allows for strategic advantages against particular opponents, especially those with Fire or Ground type moves. While not natively available in the second generation, workarounds such as trading from the first generation games (via the Time Capsule) made it a sought-after creature.
