I drew this a few years ago. Its my alternate version of Nero's Red Queen from Devil May Cry 4.
Unlike Red Queen, Blue King can allow Nero to stap and has an extra Exceed Gauge. Also, unlike Red Queen which is nitrous injected, Blue king runs on alcohol like dragsters. As you can guess, Blue King produces blue flames, which we all know is hotter than red flame. It also lacks a hand break as well as not being able to turn its handle. This is because it uses a pulling system instead (I don't like to copy). To get an idea of size difference, the Blue Kings blade is out further than the Red Queen's fall off point near the handle.
The final feature of Blue King is that it can allow Nero to travel or launch long distances with the sword alone.
