water Pokemon rule. put out fire and drown plant life and not to mention other ppl

That's obvious. Blastoise is the strongest as he has a type advantage, and is physically stronger than Charizard.

Not including type difference,they are evenly matched.If they were both normal types,then either one of them would win.Sorry,Im with charizard all the way!

Did you see Pokemon Johto Journeys 4rth or 3rd last epiosde?
In that Ash's charizard completly defeates gary's Blastoise in Johto League Quarter Final Championships!

Try to put out Charizard's fire, there is no way
you can hit what's higher than you stupid
turtle, knock blastoise on its back and its win XD

Blastoise ;)
