If Morana had two outlets to keep her anger under control, the first would be playing some lovely jazz music...
The next is becoming a superhero, and using her ice powers to beat the ever living tar out of the gangs and criminals that harass the local New Bedford residents...and the mobsters that hope to use the city harbor to their advantage. Hospitals know her well...
Morana thought it'd be funny to have a name rife with irony. Playing into her own hotheadedness, and having ice powers, she'd choose "Inverno" as her superhero name (It's Portuguese for "Winter"). Her parents aren't too proud of her fighting crime (let alone subjecting the criminals to extremely high medical bills), but they support her efforts to make a difference.
Whether it's in the local venues or the city streets.
