Firebender is a term for people in the fictional universe of the animated television series Avatar: The Last Airbender who can control fire. 

Although it has not been revealed as to what originally led the first Firebenders to learn the power to manipulate fire, the rogue Firebending Master Jeong Jeong hinted that Firebenders learned Firebending from the sun, as the Waterbenders (The opposing Bending art) learned from the moon. Jeong Jeong stated that that the sun is the greatest source of fire, yet it exists in perfect balance with nature; a learning Firebender must learn to emulate the sun's balance before they are allowed to progress to the creation and manipulation of fire.

Fighting style

Firebending is based on the Northern Shaolin style of Kung Fu. These martial arts feature quick, successive, ferocious attacks that evoke the uncompromising danger of fire. Unlike other bending disciplines, firebending has few defensive moves aside from blocking and dodging, although master firebenders are able to create walls of fire to absorb incoming attacks .

Firebending uses fire to overwhelm opponents before striking a fatal blow. Swift, whirling kicks and punches generate many shapes for offensive attacks. Jabs and punches produce miniature fireballs and missiles of flame, and spinning kicks create blazing rings and arcs. Other moves include shooting jets of fire from the fingertips, creating daggers of flame, fire whips, and creating whirling disks of flame. Firebenders can also control the size of their flame.

Firebender discipline stresses self-control and breath control as a means of directing and containing the fire manifested. Poor breath control means dangerously poor control of any fire generated. For this reason, breathing exercises are one of the most critical first steps for beginning firebenders.

Fire bending have very little weaknesses. It is known that firebending weakens when the sun is down as displayed in "The Seige Of The North"
