Running six issues before its cancellation and cover-dated December 2005 to May 2006, the series featured a fictional team set in the Marvel Universe, consisting of supernatural characters employed as a unit of the espionage agency S.H.I.E.L.D.

Although Marvel superspy hero Nick Fury is the title character, he only appeared in a cameo in the first issue.

Marvel returned to the concept in 2015 with Howling Commandos of S.H.I.E.L.D., a series canceled after six issues where that version featured a spiritual successor to the team that is established by S.H.I.E.L.D.

He journeys to the United Kingdom where he transforms the entire country into a fantasy realm.

Others, such as Goom, Grogg and Groot, were monsters from pre-superhero Marvel science fiction/fantasy anthology comics of the late 1950s and early 1960s.
