Pokémon Gym Leader Matching Quiz #2

Quiz Description:

Given 4 Gym Leaders from across the series*, can you match each to the correct Region, Type, Badge, and Ace Pokémon.** (This is the second in a planned series of many similar quizzes.) *Because gyms looked a little different starting in Gen 7, only the first 6 are represented. **This just means their strongest/last used Pokémon. Not trying to make trick questions.
