Charizard

Red's Charizard was the first Pokémon acquired by Red in the Kanto Region. Red obtained Charmander from Professor Oak when he was sent out to fill up the Pokédex.

Charizard is character from the Pokemon Origins anime.

In the AWA fics, Charizard is considered a student at the AWA Academy.

Appearance
Charizard is a large, dragon-like Pokémon that differs greatly from its pre-evolved form. The red skin coloration of Charmeleon is no longer apparent, as Charizard appears to have reverted back to the orange/yellow coloration of Charmander. The single horn that was on the back of its head is now two, one on either side. The most notable difference between Charizard and its pre-evolved forms are the large wings that have developed on its back, which gives Charizard the capability of flying.

Charizard's Mega Evolution form using Charizardite X is different from Charizard, as it now has a black body color and blue flames from its mouth and on its tail. While using Charizardite Y, Mega Charizard has a big horn on the top of its head and larger wings.

Personality
As mentioned by many Trainers, Red and Charizard have a great bond between them. Charizard is very loyal to Red, even when it was still a Charmander and its Trainer was rather inexperienced. In terms of power, it is one of Red's strongest Pokémon, even able to beat powerful opponents its type is usually weak against.

Thanks to this union and its power, Charizard is able to Mega Evolve, something rarely seen in the Kanto region.

Abilities
Charizard is the Pokémon Trainer's powerhouse, boasting heavy-hitting moves, above-average dash speed (slightly faster than Pikachu), and long-range attacks. Charizard's drawbacks include large weight, subpar aerial game, and slow walking speed. Its varied arsenal of attacks includes Rock Smash, a powerful frontal attack, and Fly, a recovery move that sends Charizard skyward and allows it to glide. It can also use Flamethrower to attack from a short distance, but its power decreases over time. It uses Fire Blast in the Pokémon Trainer's Final Smash, Triple Finish.
