In Ruby/Sapphire, Torkoal was the only one that could get Heat Wave.
In Fire Red/Leaf Green, Moltres can get it (nothing to fret about). But they also made it so Charizard had it as a move tutor attack. -_-
Before that, I was sure that Slugma/Macargo could get it through chain breeding, but I guess that isn't the case looking at Serebii's Dex. And Arcanine and Ninetales are new news to me, but they still don't really learn-learn it.
EDIT: As a matter of fact... Click. Psypoke says it can.
