Head Case made a brief appearance in issue six.  The idea of a tiny little guy operating this robot character struck me as vaguely funny, and it is a pretty interesting design.  To be honest, I never thought up a back story for Head Case, because his appeal pretty much begins and ends at his cool visual for me.  Now that I think of it, most of our characters are far from high concept—I think it makes for an interesting juxtaposition when you take “lame” characters and treat them complete seriousness.  It’s part of that old saying, “there are no bad ideas, just bad writing.”
