If you recruit any Warrior or Warlord, and you make them fight at least ONCE, it'll be registered, and if you reach the final evo and fight with it at least once, no matter which warrior, it'll be registered too.
This way, any wandering Warrior in the post-game with a Pokéball in the overworld, will have the Mon that you give them in the Main Story.
Heck, In the post-game most of the normal warriors I recruit from the start have the 100% link Poké in their last form.
