This is not the first -- nor the last --drawing I've done of old Z-D .
His name is pronounced 'zed,' and while he isn't a zombie, per se, he does have a corrupted life energy. Z-D's body tends toward the static rather than a more natural tendency toward the dynamic. His mood is also static, being very angry when his lifeforce was corrupted, he's is still not happy.
Ink on paper, from my sketchbook.
