Evil Alba (hereinafter EA)

Some of Alba's defining traits are the need to be free and devotion to the cause and the crew
Since Alba once exchanged her connection with her family for personal freedom, she tries very hard for her newfound family - on the ship she is a navigator, a scout, and a treasurer
EA would follow the path that her parents prepared for her - she would get married
But not for too long - after getting rid of her husband in the most unnoticeable way, she'd set off on a free voyage, but would immediately contact Thunder and gradually become his right hand, gaining his trust
And on the most peaceful day, she'd simply kill the old man somewhere on another expedition, without arousing any suspicion

And there are obvious differences in appearance, reflecting differences in personality:
- Alba does not wear trousers, skirts, or heavy jewelry - they interfere with her when flying, while her the evil version wouldn't limit herself in glitter
- Alba wears a short haircut not only for personal aesthetic reasons, but also for convenience. EA gathers her hair, but it's still long, this detail is connected with the fact that she would cleverly manipulate the entire crew, forcing them to happily do her own work, while for everyone around her she would appear to be a hard worker and an excellent deputy captain
- EA would wear a ring on her neck to evoke pity and indulgence from others

You can choose which of these two (evil Alba or Salty) you despise more
