Dr. Gravely and Billy are a scientist and his boy, co-created with writer Sean Frost. They first appeared in the 1950s horror-comedy DOPE FIENDS OF THE ZOMBIE CAFE, but have appeared in a bunch of other places (such as HEAVY METAL) as well. Here are a few short stories:
2012: Written by Justin Jordan (Luther Strode, Team 7). Inspired by two cosplayers at the 2012 Baltimore Comic Con. This is, by far, the most widely read comic I have ever drawn.
In order to increase awareness of The Bill Mantlo Project and to perhaps help raise funds for his continuing medical care, Rob Harrington put together the ROM Remix Project. I joined a bunch of other comic artists to redraw every page in ROM Spaceknight #1. This is my page.
