Koraidon and Miraidon are the two boxed Legendaries for Pokémon Scarlet and Violet, and they can both climb. In a refreshing twist, you befriend these Legendaries almost at the start of their respective stories. They become your traveling companion throughout the game, which is different from previous titles where boxed Legendaries were usually final bosses. You can ride Koraidon or Miraidon, and each Legendary has skills you can use to traverse the vast region of Paldea. You can climb mountains and hills with Koraidon and Miraidon, but that’s an ability you have to unlock in the game.

How to unlock the rise of Pokémon Scarlet and Violet
You unlock Koraidon and Miraidon’s abilities by completing the Path of Legends quest. The Path of Legends quest has you battling Titan Pokémon across the Paldea Region to help Arven gather special herbs. Every time you defeat a Titan Pokémon and feed Koraidon or Miraidon one of Arven’s special sandwiches, Koraidon or Miraidon will learn a new ability.
To unlock the climbing ability for Koraidon or Miraidon, you must defeat the False Dragon Titan in Casseroya Lake. The False Dragon is a very small Tatsugiri, which you can find on the marker on your map. The Titan Tatsugiri will be swallowed by a Dondozo as soon as you interact with it. You must defeat the Dondozo and follow it to a cave where the herb is. Beat it again, and then fight Tatsugiri. After you defeat Tatsugiri, Arven will access the herbs and make the sandwich to feed Koraidon or Miraidon. When the Legendary eats the food, they unlock the power to ascend.
How to climb
Climbing with Koraidon and Miraidon is simple; if you are facing a wall, press B to jump to the wall, and your Legendary will stick to the wall. You can climb vertical surfaces, you don’t need to hold B to stay glued to the wall. To stop climbing, hold B again to jump or get to a flat area where Koraidon and Miraidon can walk.
