Fire Boss

Description
Fire Boss is a winged humanoid being made entirely out of flames, slightly larger than an adult human.

Powers and abilities
Fire Boss has the ability to control all kinds of fire, and can use this ability to shoot fireballs or create giant dragon-head-shaped flames that can chase enemies down. He can also use the mutability of his body to change shape, although his most common alternate form is that of a giant bird made of fire. He can take control of other sources of fire to use as energy, and only gets stronger when fire-based attacks are used on him.

History
Fire Boss began life as a small spirit of fire dwelling in the magma chamber of Mt. Volcarius, an active volcano. Over the ages, he grew in size and power, but remained dormant in the volcano until some trespassers awoke him. In a fury he started rampaging in a large area surrounding the volcano until Magic Box arrived to recruit him. He then spent more time at his home, waiting for the Fighting Polygon to arrive and challenge him, until one day, his own attack gained enough sentience and power to turn on him. His attack, now in the form of Fire Foe, siphoned a great deal of energy from him, leaving him vulnerable and helpless until the Fighting Polygon returned to rescue him. After countless years, his power expanded to such a degree that he was capable of setting whole planets on fire.
