TLDR: Karone=Leon the Professional's Mathilda (Natalie Portman) & Zeiram's Iria

As a bounty hunter, Karone has been chasing the criminal trails of Divatox for years, but always seemingly falling one step short. Following the latest stream of Tox drug shipments to Earth, she now possibly has her chance to finally extract her revenge for the murder of her family. She has little concern for macabre villains or teenage Power Rangers--as long as they both stay out her way in settling her personal vendetta.

In another reality, Astronema has risen to power as the omnimous avatar of the Dark Spector--a ethereal force responsible for helping with balancing the scales between good and evil throughout the universe. A scale that has become unended thanks to the rise and threat of Lord Drakkon's empire. 

Marshalling forces to help put an end to this unnatural imbalance, Astronema and Spector's forces work on creating an ultimate weapon to topple Drakkon for good--the Gravezord. Loyal to her master,  Astronema won't suffer the likes of interlopers like Pink Ronin, Lami, or even Lord Drakkon's own Ranger Slayer from hijacking Dark Spector's grand design for their own ends...
