The Return of Swamp Thing 1989

After her mother’s mysterious death, Abigail Arcane travels to the Florida swamps to confront her evil stepfather Dr. Anton Arcane, who had been resurrected after his death in the first film.

In an attempt to stave off the effects of aging, Dr. Arcane, assisted by Dr. Lana Zurrell, combines genes from various swamp animals and human beings, creating an army of monsters known as Un-Men. Dr. Arcane captures Abby to use in his genetic experiments, but she is rescued by Swamp Thing, formerly scientist Alec Holland who was transformed into a bog creature after a confrontation with the evil doctor and his henchmen a few years earlier.

Arcane and his new hired guns track the pair and eventually re-capture Abby. During a final experiment where Arcane hopes to transfer Abby’s living essence into his own body and make himself young again, Swamp Thing assaults the Arcane compound, killing most of his men. Knocking down doors, Swamp Thing barges into Arcane’s laboratory to stop the experiment, but is attacked by one of his Un-Men, while Arcane becomes trapped under a heavy steel door. After a brief fight, Swamp Thing kills his Un-Men opponent, rescues Abby, and escapes with her before the entire building explodes, killing Arcane for good.

Swamp Thing uses his regenerative powers to heal Abby. When she is revived, she expresses her love for Swamp Thing and her desire to stay with him in the swamps. Due to Arcane’s experiments and Swamp Thing using his powers on her, Abby grows a flowering plant from her foot, signifying that she may become a female version of Swamp Thing. The two stroll into the swamps together, hand-in-hand.
