"Manhunter vs. Green Arrow" from Power Company #9 (DC, 2002) by Kurt Busiek, Tom Grummett and Prentis Rollins
Been slowly assembling issues of Power Company, which I missed the first time around (I was out of comics in the early 00s). If I'd been a bit more solvent at the time, I'm sure I would have been all over this. Kurt Busiek and Tom Grummett. Obscure characters that interest me, like Manhunter, Doctor Cyber... Bork from Brave and the Bold!! And Firestorm too. When I complete the run, I hope to review the whole thing on that other blog I run.
