Sketch a Lesser Known DC Character.

Try to draw a lesser known DC character. 
This sketch on the bottom is not mine, it's my younger cousin's. But I got permission from him to upload it. 
It's pretty good considering he is an amateur (okay maybe a little better than an amateur) at drawing.  
It's a sketch of Sgt. Rock. 

I'll give him points for the rifle.
It looks like a flamethrower. :D

This is interesting but its hard for me to think of any hero that is not much known in DC... but will research some more.
