Mobile Launch: Free-to-Play on iOS and Android

Both the Apple App Store and Google Play versions of Pokémon Champions are available globally starting June 17, 2026 . The game is free to start, with optional in-app purchases for items and cosmetics . Players who pre-registered can download and jump straight into battles.

Version 1.1.0 Update

• Pokémon and held-item support for Regulation Set M-B
• Fixes to battle visuals
• Fixes to certain network-related issues

Regulation Set M-B and Ranked Battle Season M-3

A new competitive format, Regulation Set M-B, went live on June 17, 2026, at 02:00 UTC, following scheduled maintenance . This is the second Mega-focused regulation format in Pokémon Champions and it runs until September 2, 2026, at 01:59 UTC .

The accompanying Ranked Battle Season M-3 began on the same date and runs until July 8, 2026, at 10:59 UTC (or July 7 depending on time zone) . Higher tiers — Champion and Master Ball ranks — unlock one week later on June 24 .

Regulation M-B uses the same general rules as Regulation M-A (Singles: 3–6 Pokémon set to Level 50, 7-minute match timer, 90-second team preview; Doubles: 4–6 Pokémon) .

22 New Pokémon and 16 New Mega Evolutions

Regulation M-B introduces 22 additional Pokémon to the ranked-legal roster and 16 new Mega Evolutions . Notable among them is Mega Staraptor, highlighted in official Japanese press materials . The full roster is already live on community resource sites like Serebii and Pikalytics .

Mega Raichu X and Y: Abilities and Differences

Two new Mega forms for Raichu debut with this update, each with a distinct Ability:

• Mega Raichu X — Ability: Electric Surge. Sets Electric Terrain upon switching in, boosting the power of Electric-type moves and preventing Pokémon from falling asleep .
• Mega Raichu Y — Ability: No Guard. All moves used by or against the Pokémon will always land (ignoring accuracy checks) .

This marks the first time Raichu has received dual Mega Evolution forms in the main competitive series.

Free Raichu Distribution with Both Mega Stones

To celebrate the mobile launch, all players who log into Pokémon Champions on any platform (Nintendo Switch, Switch 2, iOS, Android) between June 17, 2026, and September 1, 2026, at 6:49 p.m. PDT can claim a free Raichu plus the Raichunite X and Raichunite Y Mega Stones . The items are delivered to the player's in-game mailbox . No purchase or special event entry is required — just log in and claim.

Cross-Platform Play and Shared Save Data

Pokémon Champions fully supports cross-platform play and cross-save progression. By linking a Nintendo Account, players can access the same save data on Nintendo Switch, Nintendo Switch 2 (via a free upgrade), and mobile devices . Battles can be played against opponents across all platforms, unifying the competitive player base .

What's Next?

With the mobile launch now live, the competitive scene shifts to Regulation M-B. Players can expect usage data, move-set trends, and tournament results to surface in the coming weeks on analytics sites like Pikalytics . The next regulation set (M-C) is expected after September 2, 2026. For now, the priority is claiming that free Raichu and experimenting with the new Mega forms before Season M-3 ends on July 8.
