Pokémon Conquest features about ten legendary Pokémon. During the episodes, a character sometimes announces that a mysterious Pokémon has been spotted in a kingdom, marked with an exclamation point: a new location appears there, with the legendary Pokémon alone. It may be your only chance: bring the warlord who has the best Link with it. Here are the conditions, based on Serebii.
| Pokémon | Kingdom | Condition | Best warlord |
