Shelgon Playthrough, Competitive, and Nuzlocke Usage
Using Shelgon in a Playthrough
The Bagon line is Hoenn's Dragon-type pseudo-legendary family, evolving from Bagon to Shelgon at level 30 and finally into Salamence at the unusually late level 50. The payoff is enormous: Salamence has base 135 Attack, 110 Special Attack, and 100 Speed alongside Intimidate, making it both a powerful mixed attacker and a useful physical pivot whenever it enters battle. Generation III gives Salamence an unusual mixed profile because Dragon attacks are special while Flying attacks, Earthquake, and most Normal coverage are physical; Dragon Dance can strengthen physical Attack and Speed even though its Dragon STAB itself still uses Special Attack. The Generation IV physical/special split unlocks physical Dragon STAB such as Dragon Claw and Outrage, making Dragon Dance substantially more threatening, while the later Hidden Ability Moxie can raise Attack after each knockout and create snowballing sweeps. Mega Salamence raises Attack to 145, Defense to 130, Special Attack to 120, and Speed to 120 while Aerilate turns Normal moves into boosted Flying STAB, but every ordinary and Mega form retains a quadruple Ice weakness that must be respected.
Shelgon in Competitive Pokémon
Salamence was one of the defining threats of ADV OU from the moment it appeared, combining 135 Attack, 110 Special Attack, 100 Speed, Intimidate, a Ground immunity, and enough coverage to function as a mixed wallbreaker, Choice Band attacker, or Dragon Dance sweeper. The Generation IV physical/special split and access to powerful physical Dragon moves pushed it even further, and Salamence ultimately ended DPP classified in Ubers rather than OU. Later generations brought competition from other Dragons and Fairy-types, but Moxie preserved dangerous cleaning sets and the introduction of Mega Salamence in ORAS completely reset the family's competitive ceiling. Mega Salamence's 95/145/130/120/90/120 stats, pre-Mega Intimidate, Dragon Dance, Roost, and Aerilate-boosted Flying attacks proved overwhelming for ORAS OU and resulted in a rapid ban to Ubers, where it remained a genuine top-level threat rather than merely an exile from standard play. Its enduring counters are the quadruple Ice weakness, Rock damage and entry hazards, Fairy- and Dragon-type attacks, and faster revenge killers before setup, but few non-legendary Pokemon have matched Salamence's combination of offensive versatility and repeated high-tier relevance.
Shelgon in Nuzlockes
The Bagon line is a major long-term Nuzlocke investment because Bagon is usually obtained relatively late and does not reach Salamence until level 50, leaving a long period in which the team must protect Bagon and then the slow, defensive Shelgon. Shelgon's base 100 Defense and strong shell make the middle stage much safer physically than Bagon, while Salamence finally adds base 100 Speed, enormous offense, a Ground immunity, and Intimidate for immediate physical damage reduction. Intimidate is one of the family's strongest permadeath tools because simply switching Salamence into a known physical move lowers the opponent's Attack before damage calculations begin. The quadruple Ice weakness is the critical danger and makes unexpected Ice Beam, Ice Punch, or Ice Shard potentially lethal even to a healthy Salamence; Rock, Dragon, and later Fairy coverage also require careful scouting. Mega Salamence's dramatically improved Defense and Speed increase its margin for error, but it does not remove the Ice weakness, so the family remains strongest when its offensive power is paired with disciplined coverage knowledge.

Shelgon Biology and Behavior
Shelgon represents an extended transformation stage in which Bagon's body becomes almost completely enclosed inside six hard white shell plates made from a substance similar to bone. The shell repels most attacks but is so heavy that Shelgon can barely move, causing it to hide deep inside caves while its internal cells rapidly reorganize into the body of Salamence. During this period Shelgon is never seen eating or drinking despite remaining alive for a long time, and researchers suspect that energy stored before evolution sustains the transformation. When the process is complete, the shell peels away almost immediately rather than gradually wearing down. Even while sleeping and conserving energy, Shelgon can be observed moving its legs as though running or flying in a dream, suggesting that Bagon's fixation on the sky survives intact throughout the otherwise almost motionless pupal stage.

Shelgon Size Comparison: BETA
Shelgon is listed at 3' 7" (1.1 m) and shown in an in-chart visual comparison.

How is visual size determined?
Pokédex height is treated as the official listed measurement, but the chart uses pose-aware visual scaling so each sprite looks reasonable in a direct comparison.
For long or coiled Pokémon, the listed height may represent total body length rather than upright height. For Pokémon with floppy ears, leaves, feathers, antennae, wings, or other flexible features, the chart usually measures to the top of the solid, substantial part of the head or body instead of the tallest decorative feature.
The goal is not to replace the official height, but to make the artwork compare naturally at the size it appears to occupy.
