These are characters who arn't available at the start of the game (unlike a Starter Character), but must be unlocked. Unique conditions must be met in order to unlock a certain character. In Clash, they are unlocked immediately after the condition is met, no challenge to fight them required. OR, you can go to the "Secret Store" and purchase them with coins. You can even unlock some during the corse of Story Mode.
