If you're fighting a heavy like then catching him in a jab cancel combo is near guranteed to keep him caught into a jab 1 uptilt or jab 2 upsmash.
Charizard should become readable when you're trying to get close they'll use the flamethrower as a way of forcing you away so if you can manage to see it coming go in for a dair if your above or a fair approaching. If recovering from flamethrower is a problem then just time your descent and aether him out of flamethrower.
Most charizards have bad air game and need the ground for a solid fight though you should watch out for his fair dthrow and nair the fair has a good knockback at high percents same for his dthrow and the nair could cancel your attacks just space properly read well and you'll be fine the mu is in our favor.
