Gas Foe

Description
Gas Foe is a mysterious entity made up of an unknown number of spirit fragments that broke away from Gas Boss. This entity is completely amorphous, able to shift between any shape at will, and is nearly invisible. However, she cannot seem to be able to keep her mouth shut when creeping up behind an enemy.

Powers and abilities
Gas Foe relies mostly on its ability to remain unseen by the enemy, and can only be detected by sight by certain beings of extraordinary visual power, such as Psychic Boss. Her main mode of attack consists of sneaking up behind an enemy and choking them to death; she radiates an aura of toxicity that will immediately pollute and poison the area around her, causing decay and death at alarming speed. However, her propensity to whisper and giggle right before she strikes as well as her inability to move quickly allows some prey to escape.

History
The cloud-like entity known as Gas Boss has an unfortunate tendency to constantly shed his regenerating body. Over time, the malicious and poisonous fragments that were shed from his body coagulated to create Gas Foe. Once she was fully formed, Xob Cigam arrived to recruit her, and gave her the impulse she needed to overpower Gas Boss completely. With the return of the Fighting Polygon, she lost just enough time and power for Gas Boss to turn the tables, allowing him to temporary reabsorb her.
