- Unlike most Princesses in different anime. She is the second Princess to fight with swords the other is Sailor Moon's princess form, Princess Serenity.
- Her appearance and outfit is a nod to Xena: The Warrior Princess.
- Her role in the anime series is a blend between a Princess and a Warrior making herself as a Warrior Princess.
- When Spaak pleads his sister not to fight during their sword fight a reference in Sailor Moon Sailor Stars' Episode 200, where Princess Serenity pleads not to fight while Sailor Galaxia continues to fight her during their sword fight.
