Marvel Feature was a comic book showcase series published by Marvel Comics in the 1970s. It was a tryout book, intended to test the popularity of characters and concepts being considered for their own series. The first volume led to the launch of The Defenders and Marvel Two-in-One, while volume two led to an ongoing Red Sonja series.
Volume one
Marvel Feature was one of three tryout books proposed by Stan Lee after he transitioned from being Marvel Comics' writer and editor to its president and publisher, the others being Marvel Spotlight and Marvel Premiere.[1] The advantage of such tryout books was that they allowed the publisher to assess a feature's popularity without the marketing investment required to launch a new series, and without the blow to the publisher's image with readers if the new series immediately failed.[1]
