No. 3: Phyllis Summers Abbott

Played By: Michelle Stafford (1994-97; 2000-present); Sandra Nelson (1997-99)

Feminine Wiles: To ensnare Danny into wedlock, firecracker Phyllis pretended he was the father of her son, Danny, Jr., and faked paternity tests to prove it. She later ran down Danny's ex, Chris, on her wedding day, leaving groom-to-be and rescuer Paul impotent after the accident. She then slept with her marriage counselor, Dr. Tim, to enlist him in her schemes. Once Phyllis's manipulations were uncovered, Danny divorced her and she lost custody of Danny, Jr. Phyllis left town in 1999, but returned the following year and fell in love with Jack. Much to the Abbott family's chagrin, the pair married at Christmas in 2001.

No. 4: Tricia Dennison McNeil

Played By: Sabryn Genet (1997-2001)

Feminine Wiles: Innocent debutante Tricia fell for Ryan McNeil, lost her virginity to him, and they later married, which upset his ex, Nina. The following year, Tricia got pregnant, but miscarried. Disturbed by the budding romance between her sister Megan and grease monkey Tony, Tricia backed her car into him, but swore his death was an accident. Meanwhile, Ryan grew closer to his ex, Victoria. He divorced Tricia, who fell into an abusive relationship with bad boy Matt Clark. In 2001, she went over the edge -- literally, with Matt in the car. He died, but his influence carried over from the grave. Tricia moved in with Victor after her dad had a stroke, framed him for rape, and crashed Ryan and Victoria's wedding. Gunning for Vicki, she fatally shot her beloved Ryan. Tricia's current residence is now the looney bin.
