Lots of people like to claim that Felicia is just a rip-off of Catwoman, but I think there is one subtle difference: while Selina works best in the 'gray' area, Felicia actually kind of works as a full on hero as she's spent more time that way (how many times has she teamed up with other heroes not just Spider-Man).

Dead father Figure
Start's out as really irrepsonsible
Has a sense of fun and power from being a costumed vigilante/criminal
Hopefully a future writer notices this and re-rails her character
