So what happens when you take the creative team behind MPD Psycho and have them do a fantastical take on Dororo? You get this.
MADARA (Moryu Senki MADARA), written by Eiji Otsuka & art by Sho-u Tajima. First published in 1987 and first published in North America in 2004.
PLOT:
For fifteen years, Madara was content to spend his days in his peaceful village, helping the local blacksmith out with the aid of his nearly all-mechanical body. Then one day the forces of the evil Emperor Miroku invade, and Madara learns that not only are his mechanical parts capable of great power, but that unsealing that power and defeating powerful enemies gives him the chance to spontaneously regrow parts of his body. Now with his childhood friend Kirin at his side, Madara sets out on what just may be a journey of destiny.
