Flareon doesn't learn heatwave naturally by level. This move has to be taught to the pokemon by a move tutor. A move tutor can teach this move at any level
it depends, sometimes its level 43 and some times its level 45
Leonarage: It does not learn that move. (Sources/Proof): http://serebii.net/pokedex-dp/136.shtml
flareon is a fire type flamthrower is th most powerful Moves but you think it was fire blast.
Around level 15-20. Flareon learns fire spin at level 36, and flamethrower at level 52. Although I am playing the leaf green version, they should be the same except if you are playing Diamond, Pearl or Platinum, then Flareon learns a different attack set.
Flareon learns ember at level 16 in leaf green
He can't learn flamethrower.But you can give him a TM (flamethrower).
Moltres, flareon, (the charmander evolutions), vulpix, ninetails, mankey, primeape, ponyta, rapidash, and arcanine are some of them. Not all fire types can learn this move (like magmar)
