Shelgon is technically a pre-evolution of Salamence, but it holds its own in formats where Eviolite is allowed. Only weak to Ice, Dragon, and Fairy. It relies on priority moves or Scarf to keep up. Known as the Endurance Pokemon.
Shelgon's spread isn't flashy. Defense leads, Sp. Def trails, 2 stats clear the bar. Tough to catch and worth 2 Defense EVs, on a slow 1.25M XP grind.
The cells within its shell transform with explosive speed, preparing it for evolution.
They lurk deep within caves—motionless, neither eating nor drinking. Why they don’t die is not known.
Shelgon Weakness
AvgShelgon is weak to Ice, Dragon, and Fairy-type moves. It resists 4 types, giving it decent defensive coverage. Shelgon's physical bulk (base 100 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
Shelgon is the middle stage between Bagon and Salamence. It's a three-stage line with one more evolution to go. For breeding, takes forever to hatch with no compatible partners via one egg group. Defense has grown the most so far (+40), but there's still another 180 stats to gain in the final evolution.
How to Evolve
Breed with Shelgon to get Bagon eggs from the Dragon egg group. Notable egg moves include Defense Curl, Dragon Dance, Dragon Pulse and 7 more.

Shelgon isn't fully evolved, so it's not built for competitive play. You'll want to evolve it into Salamence to unlock its full potential. At 420 BST, it's a stepping stone rather than a team anchor.
Rock Head is the go-to ability for Shelgon. It protects against recoil damage. Its hidden ability Overcoat can work in specific setups.
Shelgon fills the balanced role. It's a physical attacker with base 95 Attack. Base 50 Speed is low. Priority moves or Trick Room are the way to go. And it's enough bulk to take a hit or two.
