Generation I and III

In the Generation I and III games, the Helix Fossil is a Key Item.

In Pokémon Emerald, the Helix Fossil (as well as the Dome Fossil and Old Amber) is found in the game data, but it is not legitimately obtainable and has no effect. The player is unable to regenerate this fossil in the Devon Corporation.

Generation IV onward

From Generation IV onward, the Helix Fossil is no longer a Key Item, and is a normal item. Therefore, multiples of them can be obtained, they can be held, and sent to other players via trading.

Trivia

• In the first Pokémon Red and Blue run of Twitch Plays Pokémon, the chaotic control scheme resulted in the player constantly using the Helix Fossil. This lead to jokes that the game's protagonist was constantly consulting it for advice. This resulted in memes that the player worshiped the Helix Fossil and fans referred to Omanyte as "Lord Helix".
  • In Pokémon Omega Ruby and Alpha Sapphire, when the language is set to French, before battle Brawly says, "J'ai découvert le secret de la vraie puissance en fixant un Nautile pendant des jours et des jours...", referencing the aforementioned meme.
