Trivia
Defeating the Elite Four using a single dual-type Pokémon will unlock three Challenge Medals. For example, using Dragonite will unlock the Flying-type Champ, the Dragon-type Champ, and the One and Only medals.
Due to the closure of the Generation V Pokémon Global Link, the Dozing Capture, Sleeping Capture, Deep Sleep Capture, Sweet Dreamer, and Good Night Medals can no longer be earned.
Indirectly because of this, the Great Adventurer, Entertainment Master, and Top Medalist Medals can also no longer be earned on a new save file. However, if the previous medals were collected prior to the shutdown, then these medals can still be obtained legitimately.
