Squadron Supreme #7

Two figures locked in a desperate mid-air struggle dominate Gary Frank's cover for this 2006 installment of J. Michael Straczynski's Squadron Supreme — one in a rust-red costume, the other in civilian clothes, both tumbling through open sky with clouds billowing behind them. The raw, kinetic energy of the image makes "Turnabout" feel like exactly the kind of confrontation where no one has the clear upper hand. It's a compelling visual hook for this Marvel series that never shied away from putting its characters through genuine peril.
