Potential Pokémon Champions leak
Mega Heatran, Mega Magearna and Mega Tatsugiri box icons have reportedly surfaced.
However, their authenticity is questionable, especially since Mega Tatsugiri's icon looks hand-drawn, most notably the Mega symbol.
To be confirmed. If legitimate, this could hint at their inclusion in the December update. Mega Heatran was already confirmed, but Mega Magearna and Mega Tatsugiri are not.
