Is Omastar Good in Gold & Silver Playthrough?

Postgame fossil revival. Omastar's special power is wasted on Kanto gym rematches that don't challenge most teams. A collectible more than a team member in Gold and Silver.

How to Get Omastar in Gold & Silver

No wild Omastar and no fossil to revive here. An Omanyte reaches level 40 to evolve, but since Omanyte itself only comes from breeding a transferred parent, the whole line starts outside these two games.

Omastar Weakness

Omastar's Rock/Water typing leaves it vulnerable to Grass, Electric, Fighting, and Ground. Grass hits land at 4x, so they're the biggest threat. 5 resistances help offset the weaknesses. Omastar's physical bulk (base 125 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Pokedex Entry

Apparently, it cracked SHELLDER’s shell with its sharp fangs and sucked out the insides.

Once wrapped around its prey, it never lets go. It eats the prey by tearing at it with sharp fangs.
