NObreathing

Character for the CA weekly contest
Chow145: Supervillain Self-Portrait
Here's my concept:
Due to a mistreatment of a rare bacteria infection as asthma that implicated steroid abuse, NObreathing, with her lungs completely destroyed, found a way to survive. She needs huge O2 quantities that only by processing Earth's atmosphere can be supplied, and that makes her not a nice person. She is bounded to a tornado machine, with the only superpower that steroids can can give: super aggressivity!
