The biggest reveal by the Pokemon Company leading up to the release of the Isle of Armor DLC Package for Pokemon Sword & Shield revolves around the brand New Legendary Pokemon Evolution Chain of Kubfu and Urshifu. Soon after arriving on the Isle of Armor, you will meet Mustard, the owner of the Dojo located within the island, who will introduce you to Kubfu. This kung fu bear is a pure Fighting Type Pokemon, the same with the ability Inner Focus.
Ultimately, Kubfu will travel with your trainer throughout the Isle of Armor on your way to the Tower of Two Fists. Kubfu will evolve into Urshifu after you defeat one of the two towers. Should you defeat the Tower of Darkness, Urshifu will be in its Single Strike Form and thus will be a Fighting/Dark Type. If you defeat the Tower of Water, Urshifu will be in its Rapid Strike Form and thus will be a Fighting/Water Type. No matter which form it is in, Urshifu will have the new ability of Unseen Fist. Both of Urshifu's Forms have special Gigantamax Forms as well, with its Single Strike Form having the G-Max Move of G-Max One Blow and its Rapid Strike Form having the G-Max Move of G-Max Rapid Flow (both doing maximum damage even if an opposing Pokemon uses a move like Protect or Detect).
