4th Gen Fire Pokemon... What Happened To Em?

[Super Puppy]

Yeah, there are only two Fire Pokemon that can be caught in the Sinnoh Dex (plus their evolutions; five if you count them). It's actually quite funny. I laughed out loud when they tried to have a Fire guy (Flint) in the Pokemon League and he got stuck with a Drifblim, Lopunny, and Steelix because there were only two Fire-types. Hahahaha! Anyway, if you want Fire Pokemon, just migrate them. Though they've never been the most common Pokemon, there are still plenty to be found in the older games. That's what I did, anyway.

There may not be many fire types, but most pokemon can learn a half decent fire move (Fire Punch/Fang or Flamethrower)

Or maybe the weather in Sinnoh is too cold for fire types to live =x

It's supposed to be pretty far north isnt it
