What the Data Mine Found
A routine update to Pokemon Champions pushed to the test server was intercepted and decompiled by the well-known data mining group Silph Research, who published their findings on their community site within hours of the update deploying. The files contained the full Season 9 Battle Pass asset package including images, internal identifiers, and reward tier assignments. While the developers have not officially commented on the leak, the contents appear complete and consistent with previous season pass structures.
The free track of the Season 9 Battle Pass contains 30 tiers of rewards including Pokeball cosmetic overlays, trainer card backgrounds themed around a mountain and storm aesthetic, and a bundle of 10 Rare Candies split across tiers five and fifteen. The free track structure mirrors Season 8 in value density, offering meaningful rewards without requiring a purchase for players who complete all tiers through regular play.
The premium track spans 50 tiers and contains a significantly more elaborate reward set. Among the extracted assets are six new trainer outfit color variants, a new Battle Arena theme called Stormpeak featuring animated lightning effects on the field borders, three exclusive Pokemon portrait frames, and at tier 50 the headline reward that has generated the most community discussion: a Mega Stone identified in the files as Flygonite.
Flygonite was previously data-mined in an earlier update as an item that existed in the game code but had no acquisition method attached to it. The Season 9 Battle Pass represents the first distribution path for the stone. Mega Flygon has not yet been confirmed through official channels but the stone existence and a set of animated transformation effect files found in the same data packet strongly suggest the Mega form will be added to the game alongside Season 9.

The New Pikachu Forme
One of the more surprising elements of the data mine is a new Pikachu Forme with assets distinct from all previously released Pikachu variants. The files contain a full sprite sheet labeled internally as PIKACHU_STORMPEAK and an audio file for a unique cry variant. The forme appears to feature a charged electricity effect around the ears and a different base color scheme trending toward a deeper yellow with dark accent marks, visually evoking a thunderstorm aesthetic consistent with the Season 9 storm theme.
Based on the data extracted, the Stormpeak Pikachu forme is likely a cosmetic variant similar to previous event Pikachu formes such as Pikachu Pop Star and Pikachu PhD, which are visual reskins without stat differences from standard Pikachu. If this is the case, the forme would be available as a Mystery Gift or event reward concurrent with Season 9 and would be functionally equivalent to any other Pikachu in competitive play.
Community reaction to the new forme has been mixed but skewing positive. Pikachu formes have a strong collector following in Pokemon Champions and previous event formes have maintained high trade value in the Player Exchange for extended periods after their distribution windows close. Players who are interested in the collector market should prioritize obtaining the Stormpeak forme early in the Season 9 window if its trade value follows historical patterns.
The developers have introduced one surprise distribution that was not data-mined before launch in each of the last three seasons, suggesting that additional Season 9 content beyond what was found in this data mine may still be undisclosed. The Silph Research group noted that several encrypted asset bundles in the update could not be decompiled and may contain additional surprise content intentionally protected from pre-launch extraction.
Flygonite and Mega Flygon: What We Know
Flygon has been one of the most requested Mega Evolutions by the Pokemon Champions player base since the game launched. Polls conducted on the community subreddit in each of the last four seasons placed Mega Flygon in the top three most-wanted unreleased Mega Evolutions alongside Mega Milotic and Mega Jynx. The development team acknowledged this player feedback in a producer letter published in Season 6 and stated that they were exploring options for Flygon, which represented the first indirect confirmation that a Mega form was in consideration.
The data-mined files include stat tables for a Pokemon identified by its internal Pokedex number followed by a Mega modifier flag. Based on the stats extracted, Mega Flygon appears to retain its Dragon and Ground dual typing and gains a significantly boosted Speed stat reaching 120, bringing it above the critical speed benchmarks for the current competitive meta. Attack and Special Attack both increase, suggesting a mixed attacker role rather than a pure physical or special set.
The ability assigned in the data files is listed as SOUNDPROOF_UPGRADE, an internal identifier not previously seen in the game files. Based on naming conventions used for other ability upgrades, this likely refers to an enhanced version of Soundproof that additionally gives immunity to one additional move category, though the exact implementation cannot be confirmed from identifiers alone. Community theorycrafters have speculated this could block Feather Dance and similar utility moves in addition to sound-based attacks.
No official announcement from the developers has been made as of publication time. Past precedent suggests the developers will publish an official Season 9 preview article two to three weeks before the season launches, which will formally introduce Mega Flygon if the data mine contents are accurate. We will update this article when official confirmation arrives.
When Does Season 9 Launch?
Based on the Season 8 end date of March 31, 2026, and the standard two-week gap between seasons observed in previous transitions, Season 9 is expected to launch on approximately April 14, 2026. The data mine files include a placeholder timestamp suggesting an early-to-mid April window consistent with this estimate. Season transitions in Pokemon Champions include a ranked reset, new Battle Pass activation, and typically a brief maintenance window of two to four hours during the changeover.
Players currently in the Diamond and Master Ball ranks of Season 8 should complete any pending season milestone purchases before the March 31 cutoff. Season-specific reward items available through the ranked milestone shop are removed when the season ends. Checking your milestone progress in the Ranked section of the main menu and spending any accumulated Battle Points on season-locked items before the deadline is recommended.
The Season 9 Battle Pass price is expected to match the Season 8 price of 950 in-game premium currency based on the file structures, which mirror previous season pass pricing implementations. No price increase signals were found in the data mine, though official pricing is always subject to change before launch. Early purchasers of the Battle Pass in previous seasons have received a small bonus tier headstart in two of the last three seasons.
We will publish a full Season 9 preview guide once the official developer announcement drops. Subscribe to our newsletter or follow our social media channels for notification when the official article publishes. In the meantime, the competitive guides on this site remain relevant for the remainder of Season 8 and for Season 9 preparation since the core mechanics and team archetypes are not expected to change dramatically with the seasonal transition.
