"Enginehead Blueprint" from Enginehead #6 (DC, 2004) by Joe Kelley and Ted McKeever
I don't know a whole lot about this quirky 6-issue mini-series, except that the mechanical protagonist is made of parts taken from relatively obscure DC characters or their equipment, people like Professor Emil Hamilton, Automan, Rosie the Riveter, Brainstorm and Doctor Cyber. He met other mechanicals, including Metallo and the Metal Men, but I don't think I've ever heard of him appearing in anyone else's book. I'm thinking of checking it out, but have never been sold on Joe Kelley's work. Anyone?
