The following Pokémon are also available for capture. However, they are considered to be unique, and therefore only one of each species can be in the League at any one time:
Legendary challenge matches will always be 1 on 1 and the legendary Pokémon is considered to be one level higher than your trainer level. Additionally, the legendary Pokémon is considered to be one evolutionary level higher than the challenging Pokémon.
If the legendary Pokémon is defeated, it will become a part of your squad and will always be one level above your trainer level. A legendary can be used in any match that is a 2 on 2 or higher, although it may be used in a 1 on 1 match with the consent of both trainers beforehand. Legendary Pokémon on a trainer's squad are only considered to be slightly more powerful than other Pokémon, but they will also be permitted to have a slightly more powerful signature move than usual.
