    *When The Titans first met Blackfire, they seemed to like her so much, Starfire was beginning to think they wouldn't need her around anymore.

    But just as Starfire thought about leaving, a couple of aliens thugs showed up to haul her away. The Titans discovered that Blackfire had framed her sister for crimes in the Centauri System. Blackfire was hauled away to prison, swearing revenge.*
