Shelgon has the Rock Head Ability, which makes it immune to the effects of recoil from moves that cause recoil, with the exception of Struggle. Its Hidden Ability is Overcoat, protects it from taking damage as the result of the effects of the weather, such as Sandstorm or Hail.
Bagon evolves into Shelgon starting at Level 30, and gains the opportunity to evolve a second time at Level 50 into a Salamence. Starting in Omega Ruby and Alpha Sapphire, Salamence can evolve into a Mega Salamence by using a Mega Stone.
Shelgon is in the Dragon Egg Group, and its Egg takes approximately 10,240 Steps to hatch. It takes Shelgon 1,250,000 Experience Points to reach Level 100.
Shelgon takes on the appearance of a dragon encased in a very hard shell.
Shelgon doesn't have any gender differences to differentiate between male and female.
In most of its game appearances, the only way to obtain Shelgon is to evolve a Bagon. Shelgon can be found at the Safari Zone's Wetland area in Heart Gold and Soul Silver, however, after placing 21 Peak Objects, then waiting 70 Days.
Shelgon appears at Endless Levels 59 & 61, Forever Level 9 and Mr. Who's Den in Pokémon Trozei!.
Shelgon appears at Mt. Freeze 1F-6F, Wish Cave 65F-69F, Wyvern Hill 9F-16F and Joyous Tower 60F-64F in the first round of Mystery Dungeon games. In Explorers of Time, Explorers of Darkness & Explorers of Sky, Shelgon appears at Sealed Ruins B1-B8 & IB1-B6 and Sky Stairway 1F-49F. Shelgon is exclusive to Blazing Adventure Squad in Mystery Dungeon 3, appearing at the Path to Treasure Valley on the odd-numbered floors from B9-B21.
Shelgon only appears during Missions in Pokémon Ranger. Shelgon appears inside the Volcano Cave in Pokémon Ranger: Shadows of Almia, and returns in Pokémon Ranger: Guardian Signs at the Interior of Faldera Volcano in the Present, and in the Dark Temple Missions Danger! Surrounded by Pokémon and Ground-Shaking Dragon Pokémon in the Past by capturing it and obtaining its Slate. Both missions have difficult bosses to beat (the latter of which features a Salamence as its Boss), making beating the missions to keep those slates a considerably difficult challenge, especially playing solo.
Shelgon can be found at Sunny Seashore Canyon 4-3 in Pokémon Rumble Blast.
Trading Card Game
Shelgon appears in a total of 11 sets and the Dragon Vault sub-set. It is listed as an Uncommon Card in the EX Dragon (2), EX Deoxys, EX Delta Species (2; both Delta Species Cards), EX Dragon Frontiers (Delta Species Card), EX Power Keepers, Secret Wonders, Stormfront and Arceus sets. Shelgon's lone listing as a Rare Card is in the EX Dragon set.
A trainer's Bagon evolved into a Shelgon towards the end of the episode Let Bagons Be Bagons!. Drake also used a Shelgon in the episode Vanity Affair. Shelgon would defeat Ash's Pikachu in a 2-on-2 battle.
Shelgon has yet to appear in any of the films as of writing.
Shelgon finds itself in the Never-Utilized Tier of Competitive Battling. While it has a good Attack and Defense Statistics, holding Eviolite give both of its Defenses a boost, making Shelgon a capable physical tank that can also hit hard.
If Shelgon doesn't have Brick Break (and Hydro Pump, to a lesser extent) in its move set, Bastiodon and Probopass will be able to wall it, set up against it and either force it to switch out or take it out. Afflicting it with a Burn will lower its Attack and limit the amount of time Shelgon will appear in battle, but the best way to take it out quickly is to hit it with Special Attacks, especially Ice-Type moves.
