In her early years, Dominique was spoiled and pampered. Her mutant powers manifested when she was attacked by armed gunmen at school. Many years later, her father and brother met with violent ends, which Dominique blames herself for not preventing. At the funeral, a young Killjoy, one of the SHOCS who stayed with Cyberdata after Cyberforce split, is shown smiling over a young Dominique’s shoulder. After their deaths, Dominique left Chalenne, and traveled the world as a freelancer. She studied to become a doctor, while simultaneously joining with freedom fighters in the Middle East. Eventually, she grew unhappy and ended both her role in the Middle Eastern conflicts and her studies to become a doctor. She was eventually approached by Cyberdata, joined them, and was transformed into the cyborg Cyblade. She served as a SHOC until Dr. Corben, Heatwave and Stryker left Cyberdata to form Cyberforce. Dr. Corben revealed to her the atrocities she had been committing while under the control of the brain box and Cyberdata and, appalled, she allowed him to remove the device. When Heatwave and Stryke left, she went with them. She had her father’s nuance as a highly skilled businesswoman and amassed a small personal fortune, both before and after her tenure as a SHOC.
In Issue #34, Dominique’s resurrected brother Michel informed her that their father had sold many of the people of Chalenne to Cyberdata, and that the corporation had not granted them powers, but merely enhanced and activated latent meta-human powers within each of the SHOCS. It was further hinted that the Cyberforce characters were mutants or “meta-humans” in the X-Men/Cyberforce one-shot comic, which united the two most glaringly similar pairs of characters in the X-Men/Cyberforce universes, Wolverine and Ripclaw, and Psylocke and Cyblade. The crossover introduces Ripclaw and Cyblade to two Marvel villain staples, The Hand ninjas and the Sentinels, and takes place in Japan. With the two members of Cyberforce captured by the Sentinels, a wandering Wolverine and Psylocke locate and free the two metahumans, then both teams destroy the Sentinels. With the relaunch of Cyberforce in 2006, Cyblade is again shown in her role as commander, though she steps down for the resurrected Heatwave.
Cyblade has the mutant ability to generate "blades" of electromagnetic energy from her fingers. She can psionically control this power any distance from her, as long as the target is within her line of sight. Her only limitation is that the power dissipates as it travels through the air. Thus, if she fires upon someone who was 25 feet away, they are hit with the equivalent of 25,000 megawatts of power. But, if that person is 2,500 feet away, they are only hit by roughly 500 megawatts. Her blades generate heat up to 5000° Celsius, so they cut through many materials. Cyblade has also had years of martial arts training, and she is adept at the disciplines of Aikido and Jeet Kun Do. Her powers can vary between controlled blades and projectile discharges, dependent on artistic discretion and license. She is also an expert swordsman, martial artist, and tactician, owing to her upbringing.
