"Who is the master of each type?"

Lance is the dragon master. There’s Claire, Drake, drayden, Iris, Drasna, and probably s few others I’m forgetting, but only one is known as THE Dragon master (funny considering his party has quite a few members that are not even part dragon type).I realized today that I’ve played all the games and never thought about who is the master of each type.So for the 18 types we have, who is the master of each one? Doesn’t necessarily have to be an elite four member (ain’t nobody got time for that, some want to just chill at their gym or run an evil organization)Edit: This might help selectionhttps://m.bulbapedia.bulbagarden.net/wiki/Type_expert via /r/pokemon https://ift.tt/2rp0GDk
