Philomena Dusk

Philomena Dusk is a character that appears in Bakugan Battle Planet. She is the older sister of Benton Dusk and runs AAAnimus Inc. She owns a Haos Apollyon.

Philomena is Benton Dusk's older, meaner, and smarter sister. After Benton had serious falling out with his father, Philomena took up the mantle of Chief Officer of the Dusk business empire and took it to every corner of the planet. Ruthless and pragmatic, Philomena has no love for her wayward brother Benton. If anything, she would relish taking him completely out of the picture. With an intimate knowledge of the Bakugan phenomenon, Philomena has spent a fortune attempting to unlock their secrets and bring their vast potential to bear for AAAnimus Inc.
