"What is the Witchblade?
For thousands of years it has existed. An intelligent, symbiotic weapon of incredible power. A living gauntlet that becomes one with its wearer. The Witchblade: Only women of unmatched strength of mind, body and will have ever successfully worn it. Its legacy has created a warrior bloodline back through time and forward into the future. Joan of Arc wielded the blade as did other great warrior women throughout the ages. But to wear the Witchblade is to be both its master and its servant, as this mysterious weapon draws to it what it needs and casts aside what it does not. Stirring to life at times of crisis -- during wars, famines, pestilence -- the Witchblade has been used to cut a swath of blood and viscera through the ranks of previously insurmountable evil. For decades it has lain dormant, but now in the early days of the 21st century, the Witchblade has chosen a new bearer of its power.... and its curse."
The WitchBlade is a bracelet which expands itself into a gauntlet and eventually a full armour suit with a integeral sword as well as other weapons. It cam only be used by women, and only fully by some women known as blade wielders.
