Sign Up for the Terastal Crescendo Online Competition
Get ready for dazzling Double Battles that are bound to be brilliant.
Ranked Battles Season 35 is underway in the Pokémon Scarlet and Pokémon Violet games—and registration for the upcoming Terastal Crescendo Online Competition is now available! In this competition comprised of Double Battles, you’ll take a team of just two Pokémon—one of which must be Koraidon or Miraidon—into battle. You’ll Terastallize together in terrific battles against other Trainers and earn rewards just for participating.
The Terastal Crescendo sign-up period is open from Thursday, September 25, 2025, at 5:00 p.m. PDT to Sunday, October 12, 2025, at 4:59 p.m. PDT. You may register after the event period has begun, but we encourage you to sign up in advance to jump right into the competition when it starts!
For Terastal Crescendo, the only special restricted Pokémon that can be selected for battle is Koraidon or Miraidon. Only Pokémon obtained in Pokémon Scarlet or Pokémon Violet—including those found in The Hidden Treasure of Area Zero—or those transferred from Pokémon HOME are eligible for your team. Certain Pokémon may not be used.
Choose the most Tera-rific partner Pokémon for Koraidon or Miraidon, Trainers, and sign up for the Terastal Crescendo Online Competition!
