I'm good with quite some types, but Fire is probably the type that I would consider my specialty. I believe Fire is one of the best types, since it has many great Pokémon (Heatran, Infernape, Blaziken, Ninetales, etc.) and it has a really nice weather to back it up. So yeah, Fire types are my specialty.
Fun Facts:
-Water is my favorite type. I find it funny since it is the opposite of Fire.
-When I was a kid I disliked Fire types. Now, as a fifteen year old guy Fire types are my second favorite type.
