Jason's Charizard is a elderly and powerful Pokémon, caught by Jason's grandfather some time ago. Back then, it was still a Charmander. He caught Charizard sometime near the end of his career as a Pokémon Trainer, but he still managed to train it and fully evolve it into a Charizard. Charizard currently resides inside the Old Ball that it was captured in, and is the possession of his owner's grandson, Jason Reid.
Unlike its pre-evolutions, it has wings that can allow it to fly. Charizard is a very dragon-like Pokémon. Like its previous forms, it has a long tail with a fire burning at the tip. It has extremely sharp claws, a long neck, and two horns protruding from the back of its head. The front of its two wings is blue, while the back is orange like the most of its body. Although hardly visible, Charizard's iris is light blue in color. Its belly and the undersides of its feet are cream-colored. Jason's Charizard has brown markings on it's body, possibly a side-effect of age.
As its pre-evolutions could, it can use a variety of Fire-type moves. Being the last evolution of a Fire-type starter, Charizard has the ability to learn Blast Burn. Its fire is incredibly hot, and described to be hot enough to melt boulders. Because of the wings it has grown upon evolution, Charizard can fly and can use many other Flying-type abilities, and its wings are able to carry it close to an altitude of 4,600 feet.
It also has access to Dragon-type moves, such as Dragon Claw, DragonBreath, and Dragon Rage as well as Dragon Pulse. It also is able to use many variations of clawing moves such as Slash, Cut and Shadow Claw, and can expel obscuring smoke to lower the accuracy of its opponent.
Since Charizard is a fully evolved Pokémon, it can use Hyper Beam and Giga Impact.
It's ability Blaze increases the power of a Fire-type move by 1.5× if the user has less than or equal to ⅓ of its maximum HP remaining.
