The mobile launch of Pokémon Champions also marks the debut of Mega Raichu X and Mega Raichu Y, Raichu's Mega Evolutions introduced in the "Mega Dimensions" DLC for Pokémon Legends: Z-A.
To celebrate, a free distribution is planned: log in between June 17 and September 1, 2026 to claim a Raichu together with both Mega Stones, Raichunite X and Raichunite Y, from your in-game mailbox.
Their abilities are finally confirmed: Mega Raichu X has Electric Surge, setting Electric Terrain for five turns, while Mega Raichu Y gets No Guard, making every move land. Two very different profiles to build around.
