- "Aww, why so serious all the time?"

Tornada, the Goddess of Air, also known by her experiment codename, PG-004 (pronounced "Pee-Jee-Double-Oh-Four), is a character from SolarBlaze's episodic fanfic, Knuckles' Chaotix: Elements of Power. She is a creation of Dr. Nega's, and the second to last in his line of Parallel Goddess Experiments, modeled after her dimensional equivalent, Storm. Like her older sisters, Tornada has made her debut in Dimensional Chaos.
So far, most of the Parallel Dimension Goddesses have some aspect of their personality that's the exact opposite of their dimensional counterparts; Tornada is by no means an exception. Unlike Storm, who's usually uptight and serious, never (or rarely ever) smiling, Tornada is a lot more cheerful and upbeat, sometimes to the point of annoying those around her.
In addition to the above, Tornada is also a bit clumsy, and lacking somewhat in the intelligence/common sense department, causing many people to see her as a "ditz" or an "airhead". Despite these qualities, she's still quite capable in combat, and is no one to take lightly as far as her abilities are concerned.
Tornada is the younger sister of Stonia. Woodra, and Electra, as well as the fourth and second-to-last of Dr. Nega's Parallel Goddess Experiments that he created after he, Volcana, and Metal Blaze raided Dr. Robotnik's base and stole the blueprints for the EG Experiments and the Egg Merger.
After deceiving the Wave Goddess, Oceana, into believing that he posed no threat, and was merely working on these projects for the benefit of mankind, Dr. Nega asked her for a blood sample; a request that she willingly complied with. After creating the Nega Egg Merger, and infusing Oceana's blood and an ordinary, colorless gem with air/wind-based element samples, this eventually resulted in the creation of PG-004/Tornada, followed by Goldra sometime afterwards.
