Furious Feline Foes of Teen Titans: Cheshire and The Cat

Cheshire was originally Jade Nguyen, a Vietnamese womAn 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 to bring Nguyen in to justice. Having a child together made things more complicated. She later battled Speedy's Teen Titans, and eventually left her daughter in the care of the child's father as Roy had legal status.

The Cat was a mysterious criminal strategist who led a master thief using a specialized mask with a radio transmitter to coordinate a gang of crooks. After a number of appearances, Earth-Two's Ace Archers of Green Arrow and Speedy were called into to bring the Cat to justice. After a couple of clashes, the second involving the capture of Speedy, led to the big reveal that the Cat was a feminine feline. What motivated her into adopting the alias of the Cat is unknown*, but the red-haired lady seemingly quit her criminal career following this caper.

* It is quite possible the Cat's inspiration was the original Cat, aka Selina Kyle, who made a well-known name for herself as Catwoman years before this.
