Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition. The flame is the visible portion of the fire. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems across the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Fire has been used by humans for cooking, generating heat, signaling, and propulsion purposes. The negative effects of fire include water contamination, soil erosion, atmospheric pollution and hazard to life and property.

Flying Dragon, known in Japan as Hiryū no Ken Twin (飛龍の拳ツイン, Hiryū no Ken Tsuin?, "Twin Fists of the Flying Dragon"), is a fighting game with role-playing video game elements that was developed by Culture Brain and released for the Nintendo 64 in 1998. It was published in Japan by Culture Brain, and by Natsume in North America and Europe. Its most notable feature was the game's SD mode that featured a character progression system, in which characters advance in levels as they become more experienced, and in which it is possible to collect credits and treasure items to equip characters with. The game received relatively low scores on specialized reviews at the time of its release. It had a sequel a year later, titled S.D. Hiryu no Ken Densetsu. Flying Dragon was also an NES game released by Culture Brain in 1989, where the player controlled a martial artist trying to recover magical scrolls stolen by the evil Tusk Soldiers. It was afforded a nominal sequel with Flying Warriors.
