red queen (sword)

Nero's sword in Devil May Cry 4. The Red Queen is a customized version of the blades used by the Order of the Sword and designed by Agnus. It has an ornately etched base, and appears to be modeled after the German Großes Messer (lit. "Great Knife"), but its most unique feature is that it has been specially customized with a motorcycle-like gear shift which, when pulled, spays a flammable propellant across the blade and opponent, greatly increasing the power of its blows.
