Mr. Zero

Mr. Zero is a mysterious villain whose identity currently remains hidden, despite having a feared reputation in both the west and the east. Despite its size, not many people can actually predict when Mr. Zero comes in for the strike until the very last second. Mr. Zero acts very quick, with its most common robberies being that of powerful grimoires. This can explain why the clover kingdom usually have a hard time catching the "creature", due to its speed and the nature of its Grimoire. Some have speculated who Mr. Zero truly is, some theorizing that it was originally a woman from the clover kingdom who had disappeared after being unable to pay debts to the local gangs. Or even a magic knight turning rogue, seeing as how the villain life would benefit it more. Its true identity remains a mystery that has formed a following that sees Mr. zero as a celebrity rather than a villain.
