9. Monsters Unleashed #1 - 11 (Marvel, 1973-75)
I didn't have time reread this run, so I am basing it's place on my list on my admittedly faulty memory. However, I am nominating it on the strength of the fantastic "Frankenstein 1973/1974" storyline that ran through the majority of the run. Written by Gary Friedrich (with Doug Monech taking over for the last few installments), this tale deals with Frankenstein's Monster being awoken in the modern world and attempting to make his way through a world in which he is even more an outsider than he was originally. Free from the constraints of the Comics Code, Friedrich was able to tell a much darker tale than the one unfolding concurrently in Marvel's mainstream Frankenstein's Monster book. Friedrich did an excellent job of capturing the essence of Shelley's noble monster trapped in a world he never asked to be in. This was ably assisted by evocative black and white art, initially by John Buscema and later by Val Mayerik.
And a couple of covers by Boris Vallejo don't hurt either.
