Pokemon Yellow

Omanyte Yellow Guide

  • Revive the Helix Fossil at the Pokemon Lab on Cinnabar Island. The Helix Fossil is found at the end of Mt. Moon. Choose between it or the Dome Fossil.. Omanyte is revived at level 5. Give it Rare Candies or experience-share if you want it ready for the late-game. Note: this fossil is only available in Yellow. The other version of Yellow has a different fossil.

  • In Yellow, Omanyte does the job early-game if you need a Rock/Water type on your team. Evolve it into Omastar before the later gyms and it holds up fine through the story.

  • In Yellow, Omanyte plays as a support. It's slow, so Trick Room or priority moves are key. so pick your spots carefully.

Game Availability

Omanyte has been part of the series since Red & Blue, appearing in 19 titles across all 9 generations. As a Gen 1 original, it's one of the most consistently available Pokemon in the franchise.
