Allison (Nikki Ziering) is a villainess from the 2002 comedy, Serving Sara.
She is the personal trainer for main antagonist Gordon, and was sent after Joe once he and Sara discovered Gordon working out at a gym. Joe was reluctant to fight due to his unwillingness to fight a women, but that didn't stop the evil Allison from fighting him. She easily throws three quick punches to his face and knocks him down with a kick. Joe finally attempted to fight back against the villainess, but Allison's assault continued by placing him in a headlock. While in the headlock Joe comments on Allison's tight butt. This further angers her as she sends him through a running treadmill Gordon was running on. She adds insult and further injury by kicking him in the groin as he becomes aroused during the beating. She finally gives him a knockout punch standing over him and walks off to continue her workout.
