Greg Capullo is adding fuel to the speculation fire, tweeting out a strong suggestion that he's set to work on a Swamp Thing comic. The post follows rumors that originated this summer, when Capullo told a fan at a convention that he was set to tackle the fan-favorite DC Comics monster after he wraps up his work on the hit event series Dark Nights: Metal.

Asked, "Which comic should I frame next in my room? (Whoever responds first wins)," Capullo replied promptly, "My first Swamp Thing issue when it comes out."

Swamp Thing's last ongoing series kicked off with the dawn of DC's New 52 initiative, under writer Scott Snyder and artist Yannick Paquette. After the series' conclusion with its 40th issue, the character starred again in his own series from the veteran comics team of Len Wein and Kelley Jones. The miniseries ran for five issues in 2016; Swamp Thing hasn't had a starring role since.

Created by comic book legends Wein and Bernie Wrightson, Swamp Thing made his debut in 1971's House of Secrets #92 before starring in his own ongoing series. The character would see a revival in the '80s under Alan Moore and Stephen Bissette, among other revered artists, as the character skyrocketed to international stardom, while cementing Moore as one of the most influential comic book writers of the '80s.
