Previously i think in the idea that a superheroine with giant breasts can use her breasts like if it's Thor hammer, you know, punch criminals and also using it to fly because unlike other superheroes, Thor can't do it but he uses the laws of physics with his hammer to compensate it.

So yeah, her breasts are her powers to fight crime despite she's captable to fight hand to hand, using a special suit that allows control her own gravity in a low scale to make possible carry her giant breasts and to use it as a weapon or like a vehicle that needs of her natural tornado skill to make it possible.

Tasmasteroid is a "respectful" hero who previously was a astrologer until she crossed with an alien spaceship, for the curiosity, she tries to know what's inside the ship but it explotes before she entes, giving some cosmic radiation that instead of giving powers, just make her breasts grows a lot and gives her the fortress to spin without any complications. The only thing that survives from the explotion was a suit that only makes comfortable the whole situation.

She became into a hero because looks like a place where voluptuous women can be taken a little bit seriously even if everything is ridiculous unlike astrology, also to make useful her strange condition after see her breasts can break metal.

Unlike Milkshaker who is infamous for her looking, she's something beloved at the point close of 70% of her villains are just people who wants to fight aganist her because wants to be punched by her breasts... At least she earns on merchandise and many heroes wants something with her.
