The Battle Arena now fits in your pocket. Pokemon Champions, the competitive battle simulator that launched earlier on Nintendo Switch, arrives on iOS and Android today, June 17, and it brings the full battling experience with it. The Pokemon Company International is positioning the mobile release as a true companion to the Switch version rather than a cut-down spin-off - complete with cross-platform play and cross-save progression through a standard Nintendo Account.
That cross-save support is the part dedicated trainers will care about most. Build a team on Switch, pick up your phone on the commute, and your roster and progress travel with you. Pokemon Champions is free-to-start with optional in-game purchases, lowering the barrier for lapsed competitive players who have wanted a dedicated, accessible place to practice team-building and battle strategy without the overhead of a full mainline RPG.
A simulator built for battling
Pokemon Champions strips the experience down to what competitive players actually want: deep, strategy-driven battles. It is designed to be the go-to home for honing teams and learning matchups, with a training suite aimed at helping newcomers and veterans alike understand the mechanics that decide high-level play. Bringing that to phones - where a quick battle fits neatly into a spare few minutes - is a natural fit, and the seamless handoff between Switch and mobile is the glue holding it together.
A free Raichu to celebrate launch
To mark the mobile rollout, The Pokemon Company International is running a cross-platform log-in campaign from June 17 through September 2. Players on both Switch and mobile can claim a free Raichu, and - more enticingly for the competitive crowd - two brand-new exclusive Mega Stones: Raichunite X and Raichunite Y. Mega Raichu making its debut as a launch incentive is exactly the kind of hook that gets theorycrafters experimenting, and it neatly rewards players for logging in across whichever platform they prefer.
Part of a bigger update
The mobile launch arrives alongside a broader game update, underlining that Champions is being treated as a live, evolving service rather than a static release. With cross-play uniting the Switch and mobile player bases into a single pool, the competitive ladder should feel busier from day one - a meaningful boost for a game whose entire appeal rests on finding good matches quickly.
Pokemon Champions is available now on iOS and Android as a free download, with optional purchases, and supports cross-play and cross-save with the Nintendo Switch version. Pre-registration ran ahead of today's launch, so anyone who signed up can jump straight in and start claiming their Raichu.
