Blaziken is a bipedal, chicken-like Pokémon. The majority of Blaziken's body is red with accents of beige, yellow, and gray. Behind its head, there are beige, hair-like feathers that continue downward and surround its chest and abdomen. It has a small red face with a V-shaped crest on its head. Blaziken's blue eyes are semicircular with yellow sclerae, and its mouth is similar to hooked beak. It has featherless, gray hands with three fingers each, and three clawed toes that are not normally visible due to the shaggy, yellow feathers on the bottom of its legs. A female has a shorter mask and hair than a male.
Blaziken has strong, muscular legs that give it great lower body strength. This lower body strength helps its kicking and jumping abilities. Blaziken's wrists have gray wristband-like markings capable of producing a tuft of fire above them. Blaziken can also make flames spout from its ankles. This allows it to cloak its feet or fists, and it uses these abilities while practicing a form of martial art. These combined abilities allow it to use its former signature move, Blaze Kick. Its flames burn more intensely when it faces stronger opponents. Every several years, its old feathers burn off, and new, supple feathers grow back in their place. While Blaziken is rarely found in the wild, it is known to inhabit grasslands.
As Mega Blaziken, it loses its yellow markings, and gains black markings on its upper legs and chest. Its hair-like feathers take on a wing-like shape and point upward, and the portion around its chest is rough around its shoulders. The crest on its head changes into a flat horn that curves backward. The fire it creates on its wrists is now longer as well. When Blaziken Mega Evolves into Mega Blaziken, it further hones the power of its kicks, always a source of pride to it. As it unleashes a flurry of savage kicks, its legs can begin to burn from the friction of the surrounding atmosphere. As Mega Blaziken's body temperature increases, its power and speed continue to ramp up. 
"A Blaze Pokémon. When up against a tough opponent, it fights a spirited battle and shoots white-hot flames from its wrists. The stronger the foe, the more intense the flames from its wrists. Blaziken also uses a combination of punches and kicks to leave targets in scorched ruin, and its strong legs allow it to easily leap over 30-story buildings."
NA: Blaziken would be the perfect star for an intense, action-packed movie. Its fiery fists pack a serious punch, and it has no problem leaping over 30-story buildings. We'd save so much on the special effects! All we need is a good name... How about Fired Up! Better yet, Fired Up 3! That way it sounds like it's already a popular series!
PAL: We should make an action film starring Blaziken. With its fiery fists and ability to spring over 30-storey buildings effortlessly, we'd save a ton of money on CGI! Let's call it... Red Renegade! Or, better yet, Red Renegade 3 - then people will think it's part of a popular series!
NA: If you find yourself in possession of a Blazikenite, you can use it to Mega Evolve Blaziken into Mega Blaziken. This Pokémon is clearly ready for a fight. This Mega Evolution has polished its attacks and is awaiting a worthy opponent. The Blaze Kick it can unleash will leave its foes charred. Mega Blaziken has what it takes to become a fighting champ!
PAL: If you're lucky enough to get your hands on a rare Blazikenite stone, your Blaziken can Mega Evolve into this magnificent Pokémon. Ablaze with fighting spirit, Mega Blaziken has honed its skills to the highest possible degree. With its Blaze Kick, it can deliver a fierce impact that will leave opponents charred!

Mega Blaziken is the only Mega Evolution officially introduced in Pokémon X and Y that is not native to Kalos.
Blaziken is probably based on a cockfighting chicken, specifically the Japanese Shamo chicken breed known for its mane and upright posture. The feathery legs resemble those of a Cochin chicken. It bears resemblance to Horus and Ra, two anthropomorphic ancient Egyptian deities with hawk heads. Blaziken may also be based on the Basan, a legendary fire-breathing chicken, or possibly the karura. It is somewhat based on the mythical phoenix, as its feathers burn off every few years. It may also draw inspiration from the taimatsu-maru, creatures that resembled raptors or tengu and trailed flames.
Its Fighting type may also draw inspiration from Muay Thai fighters, since Blaziken's official artwork depicts a typical flying knee and Mega Blaziken's stance portrays a check.
