Seeing as To Be a Tomboy is dead for now, pending an eventual rewrite...
Usagi:
1) Usagi was very happy when her daughter Chibi-Usa was born, but was surprised when she was born before the Great Freeze. She was even more surprised when she found out that she and the others had prevented the Great Freeze from happening... and managed to get involved in Politics.
2) Usagi managed to get the world united under one banner, when the invaders came. She and the other Senshi stood side by side with the armies of the world, prepared to stop the alien threat. It was because of her leadership here that she became Neo-Queen Serenity... The world was on her side.
3) Neo-Queen Serenity considered the cleansing that had been talked about in the future, but decided against it. Instead she offered to use her crystal to extend the lives of those subjects who desired it.
4) When the serial killer known as Death Phantom was brought before her, the courts left her two choices for the man: the death penalty or exile. Being merciful, she chose to exile him off planet, knowing what this would likely mean for her future. Still she prepared for it.
5) Oddly enough it was Akane who eventually taught Usagi how to cook. The two of them together managed to destroy four of the royal kitchens before they got what they were making right. Pity the royal cleaners.
6) Neo-queen Serenity stepped down from her throne after her elected time was up, giving the throne up for a senate seat. She made sure to train her successor in the politics of the seat, and was applauded for a successful reign.
