The Dees

Gandra Dee. I learned there was one in the original Ducktales. I read that she was a spy in both versions, so here's my AU:

The original Gandra is a single mother with a daughter named after her: Gandra Dee II (her little "DeeDee"). She starts off single until after she becomes an agent of F.O.W.L and meets her daughter's father. They have a relationship, but he ultimately wants to end things. When she refuses to give up on their relationship, he crosses a line that he swore he'd never cross: murder. He then becomes corrupt and leaves her a single mother. She resigns from F.O.W.L and raises DeeDee (who eventually prefers to just be D) to know about her father but never to trust him. Sadly, D's curiosity and intellect leads to her running away from home to find and be with her father...as a F.O.W.L agent.

Their clothes are cyberpunk style.
