In this case, we have an early character who plays the role the far more iconic character plays so they could be seen as a prototype of their successor in many ways.
Alica from Batman 89
Basically, Jack Napier's girlfriend whose supposed to be dating his boss, later takes on a white mask. This character can be seen as a prototype to Harley Quinn who would be introduced a few years later in Batman: The Animated Series.
Lotus Blossom from the original Ninja Turtles cartoon
She's a deadly warrior, a thief, has a rivalry/relationship with Leonardo who sees some good in her and wants to change her. These roles are usually given to Karai in later adaptations who in the comics wasn't introduced until 1992 and would be introduced to a wider audience in the 2003 show.
