Charizard Charmeleon Charmander
trade from leafgreen or firered
You can't catch Charizard in Diamond. You'll have to migrate or trade Charizard to get it in Diamond. You can have a Charizard in FireRed/LeafGreen and HeartGold/SoulSilver and X/Y, if you evolve Charmeleon. To get Charmeleon, you need to evolve Charmander or in X/Y you can find it at the Friend Safari. In FireRed/LeafGreen Charmander is a Starter from prof. Oak and in HeartGold/SoulSilver you can get it as reward from prof. Oak for defeating Red.
You can't evolve Charizard, because it's the last form of Charmander. Charmander (lvl16) -> Charmeleon (lvl36) -> Charizard. Good Luck!
Trade from firered or leafgreen... or cheat... but don't cheat.
get charmander as a starter and it will evolve into charizard eventually
all you have to do is not get beaten
Charizard is the late evolved form of Charmander which is a starter pokemon at the start of Pokemon Firered you can only get this pokemon through the beginning or by trading one from another Firered or even Leafgreen.
U either cheat or transfer from leafgreen or fire red
