In 1991 DC sought to revive interest in Swamp Thing by bringing horror writer Nancy A. Collins on board to write the series. Starting with Swamp Thing Annual #6, Collins moved on to write Swamp Thing (vol. 2) #110–138, dramatically overhauling the series by restoring the pre-Alan Moore tone and incorporating a new set of supporting cast members into the book. Collins resurrected Anton Arcane, along with the Sunderland Corporation, as foils for the Swamp Thing. Her stories tended to be ecologically based and at one point featured giant killer flowers.
With issue #140 (March 1994), the title was handed over to Grant Morrison for a four-issue story arc, co-written by the then-unknown Mark Millar. As Collins had destroyed the status quo of the series, Morrison sought to shake the book up with a four-part storyline which had the Swamp Thing plunged into a nightmarish dreamworld scenario where he was split into two separate beings: Alec Holland and the Swamp Thing, which was now a mindless being of pure destruction. Millar then took over from Morrison with issue #144, and launched what was initially conceived as an ambitious 25-part storyline where the Swamp Thing would be forced to go upon a series of trials against rival elemental forces. Millar brought the series to a close with issue #171 in a finale where the Swamp Thing becomes the master of all elemental forces, including the planet.
