Infernape is hands down the best Fire-type starter to me and overall my favorite Fire-type as well. I love its design and the Fighting sub-type only makes it way more awesome. Charizard, well, I don't really like the species, but it isn't that bad compared to the others. Plus, Ash's Charizard is funny sometimes. ^^ Typhlosion looks cute, but sadly it is a boring pure Fire-type. Blaziken's design is really weird and Emboar would be the second in my list, should its type be Fire/Dark instead of Fire/Fighting.
