The metamutant Tatsu "Betsy" Braddock left her quiet home in England to travel the world and eventually became the sword-wielding mercenary known as Kokoro. Combining her metamutant powers with ninja training, Kokoro's katana blades are double deadly, allowing her to strike both a physical and mental blow. Kokoro found herself being hunted by the insidious android known as Sinistron, but she was saved by the timely arrival of Magneto and the Magnetic Men.
- Swords: Kokoro is always armed with her twin swords, which are double deadly, striking both a phisical and mental blow to unwitting opponents. Her "psionic" swords are actually mystical blades infused with her telepathic powers and are powerful enough to sunder both demons from Apokolips and the Tyrannoids of Latkovia
