Izzy's mother. Rizz.
At first she was going to be a much more secondary character than her daughter.
But then I realized since she is the only female character aside from Izzy, who only appears later on. I decided that Rizz had to be a stronger, more important character and also Zack's love interest.
So, I decided to make her some kind of anti-hero whom Zack has a little crush on. That's why he later becomes Izzy's foster father.
She usually kicks Zack's ass but ends up being a good ally in the battle against the empire. You know, she is the kind of person who wants to be the only one who beats up Zack for no apparent reason, so she fights the imperials as well.
