(I'm bad at titles btw)
Ever since I started playing Pokemon Y in late 2013, my friends and I were imagining which type we would use as a gym leader, based on our personalities and favourites. Now my fave type is dragon, not only based on the op-ness of the type but also because I love a lot of the dragon-type Pokemons, Rayquaza in particular, since third Gen was the Gen that got me back into Pokemon and Emerald being the first game were I finished the National Dex, and my Rayquaza there being the powerhouse of my countless rebattles against the Elite Four.
Now I tried to refrain from using any legendaries for this since gym leaders do not tend to use those, and I also faced the problem of being unable to decide which type I wanted to base on (in case you wonder which types there were, you can see the (albeit German) linstings of the types and Pokemons I considered on the sketch in my Scraps), so I decided to say "Fuck It" and just assembled a team that became a mixture of all of those types. Maybe I'm just one of the bad guys or something.
Ignore the too big keystone, for some reason I remembered them bigger than they actually are game-canon-wise.
If you can tell which 'mons I have on my team without looking at the sketch where it's more or less spelled out, cookies to you, my dear.
