It all started with that explosion at the chemical plant. A woman experimenting with methane compounds was caught in the blast and subsequently mutated. She was the only one still trapped inside who survived.
The cause of the explosion? No one knows for sure. The result of the explosion? The woman who survived left with a burn scar over half of her face and a butt the size of a yoga ball. Some say that her eyes seemed different, as though they had an evil glow to them. She was soon admitted to the hospital to treat her burns and possibly any other adverse effects that chemical explosion might have caused.
She was released from the hospital days later followed by an entourage of what appeared to be hypnotized slaves. It seemed that she had developed incredible powers in the incident, ones that would end up terrorizing the world in the future. She was given absolute control over her farts, which were given both a mind control and a mutative property. Anyone that she blasts with her ass gas is locked under her control, enthralled by her flatulence and compelled to adore her as their mistress. They also become glow eyed, dim witted, obese nudists with bad gas of their own, which also has transformative properties. Unlike the leader, these farts don’t have mind control power, but they will still make you fat and gassy, but those farts aren’t special.
The woman changed her name to Gastasia and decided the rest of her life to Saturday Morning level supervillainy. She too became obsessed with farts, and wished to turn everyone into her loyal gasbags. Her weakness, strange as it is, is floral perfume. If she gets it on herself, everyone but her first slave (the former hospital nurse) returns to normal and she starts suffering convulsions. She will have control of the world one day, she swears...
