===Supernatural===
After stealing Pool from Un Cowboy, she became the primary wielder of its power, but soon caught wind of Super and Natural, for they were in possession of Pool Knife, the source of all pool.
===Fringe===
Devoted herself to safeguarding Pool from The Organisation, enlisting the help of Mr. Feet / Mr. Head and a small boy with leukaemia.

He subsequently shot her in the head, and reclaimed pool for himself.
