Jo Slade is an overweight, abusive and downright degenerate mall police officer who acts as a boss in the video game Dead Rising, she was a psychopath (also hinted at being a rapist) who was abusing female victims and then murder them before the protagonist confronted her, trying to reason with her but failing, saying that Frank is interfering with "offical police business" and that she will start with Frank before other -thus Jo was engaged in a battle where she used a taser to paralyze the protagonist while returning to her victim, the goal of the battle is to ensure Jo is defeated while also making sure her victim stays alive.
Once defeated Jo falls on the ground complaining bitterly that she was defeated by a "worthless prick" before she dies painfully.
