Gyarados

Performance Metrics

Gyarados has a reported usage rate of 8.02% and win rate of 45.69% in BSS Regulation M-C (Pokemon Champions) (displayed tier: E). The report covers 10/12/2026 to 10/26/2026 (UTC), with 25,083 recorded battles. 1,837 wins and 2,184 losses (4,021 recorded team appearances). Usage is recorded team appearances divided by twice the report battle count; win rate is wins divided by wins plus losses for teams containing this Pokemon. Neither metric measures individual strength. Small samples can produce extreme percentages.

Usage Trends

Usage was 4.58% in the first available period (Period 1: 2026/10/12 11:01–2026/10/15 12:54 UTC; n=12,542 team slots) and 5.18% in the last available period (Period 4: 2026/10/21 16:36–2026/10/26 10:58 UTC; n=12,540 team slots), a change of +0.60 percentage points. This endpoint comparison does not describe every intervening period or explain the cause; small samples can fluctuate substantially. Periods without sample counts are excluded. Win rate was 45.64% in the first available period (Period 1: 2026/10/12 11:01–2026/10/15 12:54 UTC; n=574 recorded appearances) and 52.23% in the last available period (Period 4: 2026/10/21 16:36–2026/10/26 10:58 UTC; n=649 recorded appearances), a change of +6.59 percentage points. This endpoint comparison does not describe every intervening period or explain the cause; small samples can fluctuate substantially. Periods without sample counts are excluded.

Rating-band Observations

Across 5 available rating bands, usage ranged from 5.23% (R1298~; n=10,132 team slots) to 10.22% (~R1089; n=9,968 team slots), a spread of 4.99 percentage points. Overall usage was 8.02%. Bands use battle-average ratings, not individual player skill. Missing bands are excluded; differences are descriptive, not evidence of statistical significance.

Recorded Moves

Among the returned moves, Dragon Dance has the largest recorded team-use count (1,515; ties may occur). Move counts refer to distinct team appearances with a recorded use by this Pokemon, counting each side once per battle. The displayed percentage divides that count by this Pokemon's distinct recorded team appearances under the same report filters. Both sides of a mirror battle count separately. This is not moveset adoption. Unused moves and missing move records cannot be distinguished here. These data do not establish which move is strongest or underused.

Teammate Observations

In the returned frequent-teammate sample: Hippowdon: 41.4% wins in 2,277 recorded pair observations; Scizor: 39.1% wins in 1,933 recorded pair observations; Clefable: 39.3% wins in 1,903 recorded pair observations. These are team-level outcomes with both Pokemon on the roster, not a measurement of synergy. Other teammates, player selection and small samples can affect these percentages.

Opponent-team Observations

Returned higher-win-rate opponent group: Gliscor: 71.6% wins in 81 recorded pair observations; Sableye: 66.7% wins in 54 recorded pair observations; Indeedee-F: 60.7% wins in 61 recorded pair observations. Returned lower-win-rate opponent group: Mamoswine: 28.8% wins in 59 recorded pair observations; Heracross: 33.3% wins in 45 recorded pair observations; Aggron: 34.7% wins in 49 recorded pair observations. Wins refer to the team containing the focal Pokemon when the named Pokemon was on the opposing roster. They are not direct one-on-one results or proof of a counter; sample sizes and other team members matter.

Interpretation Limits

These summaries describe the collected battles within the report period. Team composition, player selection, repeated players and incomplete records can affect results. Differences do not establish causation, statistical significance or a recommended build.
