Some have speculated that, in a world where Charmeleon was the end of its evolutionary line, firebombing as a weapon of war would not have been developed until the invention of airships and airplanes.
Unfortunately for many of their victims – those who have seen homes burned, crops ruined, and been scorched alive – Charmeleon evolve into Charizard. And although their extreme weakness to any competent rock-type pokemon has kept them away from the massive battles of ages past, Charizard corps have continued to be used throughout the centuries to give peoples who resisted in spite of broken armies a bitter choice between surrender or massacre in flames.
Today, war is rare and international law prohibits the use of Charizard against civilian populations. The only flock of Charizard left is a small, migratory order centered around two secret training valleys, one each for summer and winter. And yet whenever they take to the skies on their majestic, semi-annual flights, many of those old enough to have lived through the war find themselves running for their lives or screaming in blind terror.
