Charizard had its chance. The Flying type is packed with better representatives.
Nope, it did not "have its chance". As a dual-typed Pokemon by definition it has two chances.
And no, Charizard is the best representative of every type. Even water. As the best and most popular Pokemon (save my contests are not a good indicator of popularity, so it not winning Fire is irrelevant) Charizard not winning either of its type categories would be a little bit terrible.
