Kiefer Bauer was a minor character on General Hospital. The role debuted in June 2009 and ended April 6, 2010, after the character's death. The role was presumably created for a SORASed version of Kristina Davis. Kiefer was portrayed by Christian Alexander.
Since his debut, Kiefer has been proven to be violent towards Kristina. In May 2009, Kiefer gets in to a bar fight with Kristina's 17-year old brother Michael Corinthos, who recently got out of a coma. Kiefer constantly harasses Michael, leading to the point where the two fight at the Port Charles Country Club. Months later, Kiefer proves to be untrustworthy when he begins flirting with another senior while dating Kristina. Kiefer helps Kristina cover her tracks in July 2009 when she ran over a pregnant Claudia Zacchara Corinthos, who later suffers a miscarriage.
Kiefer has also voiced his opinion on Sonny Corinthos but is proven to be a coward in front of him. Kiefer becomes jealous of Kristina's friendship with Ethan Lovett, which turns in to a crush. After Kristina ditches Kiefer for Ethan, Kiefer beats Kristina up. To protect him from Sonny's wrath, Kristina tells everyone that Ethan was the one who abused her. Sonny's lieutenant and best friend, Jason Morgan, realizes that Kristina is lying and convinces
Detectives Dante Falconeri and Lucky Spencer to investigate further. On April 2, they finally discover that Kiefer was the culprit.
Out of rage, Kiefer beats up Kristina again but this time, Kristina's mother Alexis witnesses Kiefer exiting the house right before finding Kristina unconscious on the floor. While driving to the hospital, a distraught Alexis runs over her daughter's abuser. Kristina's sisters Molly Lansing and Sam McCall find Kiefer's body and he dies shortly after being admitted to General Hospital. Alexis hides her guilt for a while, but eventually confesses. Meanwhile, Kristina is questioned by Dante and finally identifies Kiefer as her attacker on both occasions. The truth quickly becomes public knowledge, and Ethan is cleared of all charges and given a clean slate.
Kiefer appears one last time on June 2. Kristina has a dream of Kiefer being next to her bed, telling her to get up so they can go to the beach together. Kristina refuses, and Kiefer quickly becomes violent and slaps her right before Kristina wakes up.
