Gyarados Mega stats, sets and usage in Smogon Champions OU

This profile aggregates every signal Smogon publishes on Gyarados Mega for the Champions OU format : monthly usage rate with month-over-month delta, top moves with their pick rate, top items, top abilities, EV spread distributions, the most common Tera types, and the Pokémon's top teammates ranked by co-usage. Each datapoint is sourced from the live monthly snapshot, no editorial picks, no curation, just what high-rated players actually run.

The Checks & Counters panel ranks the Pokémon that handle Gyarados Mega most reliably, scored by Smogon's matchup score (a synthetic metric that combines win rate, switch-in safety, and KO chance). Use it to find the threats your team has to answer. The Compare button at the top opens a head-to-head view against any other Pokémon in Champions OU, and the radar chart in the hero shows Gyarados Mega's base stats relative to the format's median (so you immediately see if it's a bulky, fast or balanced pick).

The Smogon Sets panel below the analytics pulls Smogon's strategic dex sets, the curated movesets the Smogon community considers viable, distinct from the popular sets derived from raw usage. Use the popular sets when you want to mirror the metagame ; use the Smogon sets when you want a tested baseline written by tier specialists.
