While he’s not one of the most well-known characters in the DC Comics mythos, Swamp Thing has certainly collected a sizable fanbase since being introduced in the early 1970s, whether he was being published by DC proper or under the Vertigo imprint. Within the last decade, he led his own series during the New 52, and Len Wein, who co-created Swamp Thing with artist Bernie Wrightson, wrote a six-issue miniseries centered on the character a year before his passing.
