Cheshire was originally Jade Nguyen, a Vietnamese women who was trained to become a master assassin. Eventually, she met and fell in love with Roy Harper, secretly the Earth-One superhero Speedy, and together they had a baby. However, Harper was sent out to bring Nguyen in to justice. Having a child together made things more complicated. She ultimately battled Speedy's Teen Titans.
Cat's secret identity was unknown, although as the Earth-Two counterpart of Cheshire, perhaps she was also Jade Nguyen of that world. More a burglar, the Cat faced the combined assault of the Amazing Archers of her planet in Green Arrow and Speedy. She would not have occasion later to meet an adult Speedy as he and the Arrow were exiled into different eras, and reappeared decades later.
