Hmm this is a tough one and mine will also be in order and I'll do my top five for each type in order as well.
1) Flying: Gyarados, Dragonite, Pidgeot, Rayquaza, Talonflame
2) Dragon: Garchomp, Dragonite, Rayquaza, Tyrantrum, Appletun
3) Dark: Grimmsnarl, Tyranitar, Umbreon, Obstagoon, Crawdaunt
4) Water: Gyarados, Kyogre, Milotic, Toxapex, Crawdaunt
5) Fire: Blaziken, Talonflame, Charizard, Rotom-Heat, Centiskorch
Kind of cool we don't share any types, all types seem well represented!
