Best Gyarados IVs by league
| League | Rank 1 IV | Lv | CP | 15/15/15 |
|---|---|---|---|---|
| Little | not allowed — must be unevolved and able to evolve | |||
| Great | 0/14/15 | 16.5 | 1499 | #3,613 |
| Ultra | 0/15/14 | 27.5 | 2500 | #2,464 |
| Master | 15/15/15 | 50 | 3834 | #1 |
Gyarados cannot enter Little League because it has already evolved. Little League only takes Pokémon that have not evolved yet and can still evolve, so the 500 CP cap is not the only rule.

Rank 1 IVs across the evolution line
IVs carry over when a Pokémon evolves, so pick the spread for the league you mean to play it in, not for the stage you caught it at.

How good is Gyarados in the current meta?
PvPoke rates Gyarados #58 of 409 in Master League, with a score of 81.8 out of 100. The usual moveset is Dragon Breath, Aqua Tail and Crunch.
| League | PvPoke rank | Score | Usual moves |
|---|---|---|---|
| Great | #279 of 1,154 | 80.3 | Dragon Breath, Aqua Tail, Twister |
| Ultra | #78 of 851 | 87.1 | Dragon Breath, Aqua Tail, Twister |
| Master | #58 of 409 | 81.8 | Dragon Breath, Aqua Tail, Crunch |
These are two different questions. The IV ranks further up say which Gyarados to build; the meta rank says whether Gyarados is worth building at all. Ranks and movesets come from PvPoke, whose battle simulations produce them, and they move as the meta does.
How to find a good Gyarados
The search-string generator builds a string you can paste into the search bar in Pokémon GO. It matches the CP, HP and appraisal stars of the top spreads above — pre-evolutions included — so you can sweep a whole storage box in one go.
To check a Gyarados you already own, open the IV ranker and set its IVs. It ranks every stage of the evolution line at once and shows the meta rank beside the IV rank.
