This is a thread to share interesting Trivia about the games, the regions and the characters. This thread is not for personal experiences, it's for general facts, like if a Pokemon learns (or doesn't learn) a specific move, or the origins of someone's name, or under leveled Pokemon.
Here's one! Sinnoh is the first, and currently only, region lacking a Dragon specialist.
Johto: Clair (and Lance, but Indigo Plateau is in Kanto)
Unova: Drayden/Iris (Though Iris only uses half a team of dragons as Champion)
Though Cynthia uses Garchomp, and Draco Meteor was introduced. Dragon Tamers were also vastly more popular than in R/S.
