Covering the first series (1972-1976) and up to 1981…
Swamp Thing first appeared in House Of Secrets #92, and the success of that story led to the creation of a Swamp Thing series which ran for 24 issues from 1972-1976, with creators Len Wein and Bernie Wrightson contributing to the first 13 and 10 issues respectively. Swampy then guested in several Challengers Of The Unknown issues throughout 1977-1978, and notably teamed up with Superman (in 1979) and Batman (in 1981).
The series and its creators won several Shazam Awards in 1972 and 1973:
- 1972 Best Individual Story (Dramatic Division) for ‘Dark Genesis’ (Swamp Thing #1)
- 1972 Best Writer (Dramatic Division) – Len Wein, for Swamp Thing.
- 1972 & 1973 Best Penciller (Dramatic Division) – Bernie Wrightson, for Swamp Thing.
- 1973 Best Continuing Feature.

As Bliss battles Swamp Thing, Cable smashes the orb, which restores Swamp Thing’s control over his body. Nebiros temporarily takes the physical form of a demon but requires a host quickly. Father Bliss atones for his previous deceptions by offering up his body, knowing that his frail form will not be enough to contain the demon, and both he and Nebiros perish.

“Rebirth and Nightmare”, July 1976
Gerry Conway [w], Nestor Redondo [p], Ernie Chan [c]
Swamp Thing tracks down his brother Edward, a fellow scientist, who attempts to transform Swamp Thing back into human form with the help of his assistant Ruth Monroe. Swampy is attacked by John Zero (last seen in #13), who now inexplicably has a sword for a hand and calls himself Sabre. Swamp Thing manages to fend him off before transforming into Alec Holland.
These events were ignored by subsequent Swamp Thing stories and so are now considered non-canon. Then-editor Len Wein explicitly states in the letters section of The Saga of Swamp Thing #6 (Oct. 1982) that the events after Swamp Thing #21 (Mar. 1976) did not happen – specifically, that Swamp Thing never became human again and never had a brother.
Swamp Thing #24

David Anthony Kraft, Gerry Conway [w], Ernie Chan, Fred Carrillo [p]
Alec Holland tries to adjust to being human again but is attacked by Thrudvang, The Earth Master. Despite his weakened state, he manages to defeat the monster and protect Ruth.
These events were ignored by subsequent Swamp Thing stories and so are now considered non-canon. The final panel advertises a battle with Hawkman, but the series was cancelled and Swamp Thing #25 was never published.
Swamp Thing #25 [Unpublished]
“The Sky Above”, November 1976
David Anthony Kraft [w], Ernie Chan, Fred Carrillo [p]
Alec is suffering severe pains as a side effect of his transformation back into human form. He and Ruth travel to Edward’s house but find the lab smashed and Edward missing. They decide to visit a doctor but Alec transforms back into Swamp Thing against his will and bursts out of the car onto a busy highway. Hawkman, who witnesses the commotion from a spacecraft, attacks Swamp Thing but is overpowered. Hawkman then meets Sabre, who has recently finished off the injured Thrudvang. Sabre and Edward Holland (jealous of his brother’s closeness to Ruth) convince Hawkman that Swamp Thing is a dangerous criminal and must be stopped. Hawkman again engages with Swamp Thing, dropping him from a great height into a river, from which Swampy emerges again as Alec Holland and flees the scene with Ruth.
This issue was fully scripted and at least partially pencilled and inked but was never published. Scans of many of the pages have since appeared online at Heritage Auctions and in Back Issue #66 (Aug. 2013) [see Bibliography]. The plot, script, and all of the pages (including a Yanick Paquette re-creation of p. 15) can be found here. This material was later printed in the collection Swamp Thing: The Bronze Age, vol. 2 (ISBN: 9781401294229).
