So, sorry about this, but I always thougth Golbat and Senketsu had things in common (and yeah, both of them suck blood too).
Maybe I took the crossover thing a little too far, but hey, it´s Golketsu. . . yeah, is the only name I came up with.
Anyway, I know Senketsu has its patch in the other eye, but I accidentally drew the whole thing inverted, and I really don´t know how to export inverted pics in Sai.
