- "My Daddy will always keep me safe."
- —Katey Greene
During the events of "The Las Vegas Outbreak," Pam became zombified, and bit Katey on her left arm, infecting her, and forcing Chuck to constantly procure Zombrex to keep her alive. She was bit at the young age of four, and Chuck has been determined to find Zombrex for her ever since.
Over the years, the bond shared between Katey and her father has grown to be unbreakable as Chuck claims that he would do anything for her, even if it means facing a zombie horde to bring Katey a stuffed animal. Katey always needs to be given a daily dose of Zombrex to prevent herself from turning into a zombie (two doses a day in Case Zero).
Dead Rising: Road to FortuneEdit
In the first issue of the series, Katey is briefly seen at the end of the story heading to Las Vegas with her parents. She expresses her excitement over winning the big money in Chuck's upcoming motocross tournament. Chuck happily agrees with her, and promises that this trip will soon change their lives "forever".
Dead Rising 2: Case ZeroEdit
Her father dotes on her and will do anything for her after the loss of her mother, which has greatly affected both of them. She has been infected by her mother, who turned during the outbreak. The pair arrive in Still Creek after fleeing the Las Vegas Outbreak, and all is calm until the zombies appear and their truck is stolen by an unidentified survivor. She stays in the Brockett Gas Station as her father looks for Zombrex and a way out before the military arrives to wipe out everything within 50 miles of Las Vegas, including Still Creek.
Later that night, after receiving her second dose of Zombrex, a psychotic mechanic arrives at the gas station and tries to kill Katey when he learns she is infected. Chuck manages to kill the mechanic, and he and Katey escape Still Creek on a motorcycle soon after, just as the military begins their cleanup operation.
Dead Rising 2Edit
Katey comes to Fortune City with her father before the outbreak. Because of the steep cost of Zombrex, Chuck Greene becomes a contestant in Terror Is Reality in order to make money for her Zombrex. During the contest, Katey is taken to the green room by the TiR Employee. After the zombie outbreak, she is carried by her father to the Emergency Shelter where Sullivan comments on her bite. He allows her to enter the bunker when Chuck tells him that he has Zombrex although he does not.
When Chuck leaves the bunker, as he must do multiple times in the course of the story, Katey remains behind. Stacey Forsythe looks after her in Chuck's absence. At least once every 24 hours, Chuck must return to her to administer Zombrex to her; after the third dose, she becomes suddenly ill and passes out, but apparently recovers completely. If the player successfully achieves Overtime, Katey is captured by TK, along with Stacey. Both are subsequently rescued by Chuck, and leave Fortune City together.
Failure to get Katey Zombrex will result in Ending F in both Case Zero and Dead Rising 2. Failure to give Katey her Zombrex will not immediately end the game. Instead, a cutscene will play, indicating that Katey has turned. Katey then disappears from the game.
Dead Rising 2: Case WestEdit
Although Katey doesn't make an appearance in Case West, she is mentioned by Chuck at one point in a cutscene.
Dead Rising 3Edit
- Main article: Annie
After the events of Dead Rising 2, Chuck began a relationship with Stacey Forsythe, who became a motherly figure for Katey. However, in 2017 government Zombrex chipping became law, forcing Chuck to go to illegal means to keep Katey from being chipped and tracked by the government. This slowly turned Chuck into a shadow of his former self; he began making terrible mistakes. This withered his relationship with Stacey, and after it ended, Katey felt she was a burden on Chuck and ran away. She then began using her middle name, Annie, in order to evade Chuck. She soon joined the group of Illegals in Los Perdidos.
When the Los Perdidos outbreak occurs, Annie joins Nick Ramos and other survivors. Three days later, she returns to the Illegals, where they intended to fight the government who were murdering survivors.
Nick soon returns to Annie, after receiving a deal from Gary to turn her in to his boss for fuel that he could use for the plane. However, feeling guilty, Nick shortly regrets attempting to go through with the plan. He then begins working with Annie and Red.
Throughout the game Nick and Annie begin developing feelings for one another. Annie confesses to Nick that prior to the events of Dead Rising 3 she was in a relationship with Red, but this did not last. After Red turns on them, Annie assists Nick in defeating him. After Red's death, Nick and Annie's feelings for each other reach a climax and they kiss.
This is shortly followed by the return of Chuck Greene, who is revealed to be Gary's boss. Although wary of each other at first, Nick and Chuck soon become allies when they work together to stop General Hemlock from harvesting the king zombies as a weapon. Once Hemlock is defeated, Katey escapes the city along with Nick, Chuck, Dick, and Isabela Keyes.
At the end of the game, Annie and Nick begin a relationship.
- In her notebook picture in Dead Rising 2: Case Zero, Katey's pigtails are missing.
- She has a large bite mark on her left forearm, where she was bitten by her mother.
- During Overtime Mode, Tyrone King will administer Zombrex to Katey.
- In Dead Rising: Road to Fortune, she has her look of Dead Rising 2 instead of Case Zero (which is before Dead Rising 2). This could simply be an error from the artist.
- Katey has a mock PSP where she can be seen playing Mega Man.
- Even if Katey turns, it is impossible to see her zombie form, even if the player chooses to continue. Upon turning, she disappears from the game, except for her backpack. It's possible that Sullivan or another survivor killed her to protect the other people in the bunker.
- When Katey turns, she's listed as DEAD in the notebook, as opposed to other infected survivors who are listed as UNDEAD when they turn.
- She is one of the youngest survivors in the Dead Rising series.
- It is possible to level Chuck from 1 to 6 just from gifting items to Katey, without killing any enemies or rescuing any survivors.
- In the beta version of the game Katey was originally called Cindy. Evidence of this can be seen in the PC version of DR2 as all of Katey's texture files are labeled as Cindy, E.G. Her jeans texture is called Cindy jeans cm.
- In Off the Record, if you go into the green room where you find Katey in the original Dead Rising 2, you will find Katey's PSP and backpack on the floor in a pool of blood, with Frank saying, "Who would bring a kid in here?" Katey's whereabouts remain unknown, but it can presumed that she either didn't get her required Zombrex dosage (hinted at by Chuck's dialogue 'there's still some more time' or was killed/turned by a zombie, with the evidence of some form of fight (bloodstains and some child-sized bloody handprints) around the room.
- It is not known who gives Katey her daily dose of Zombrex during the events of Case West, although it can be assumed she is in Stacey Forsythe's care and thus was given Zombrex by Stacey.
- She says to Chuck at the start of Dead Rising 2, "Look Daddy, I got a new power on Mega Man!", clearly referencing Capcom's game Mega Man. However, Mega Man was never made for the PSP, so she is actually playing the Powered Up remake.
- She was seven when Dead Rising 2 took place in 2011, so that would mean she was born in 2004.
- She is similar to her father in the sense that she is appalled by larger powers killing the innocent for personal gain.
- She seems to have a strong belief in not giving up on family regardless of what it takes. This is possibly due to growing up watching Chuck desperately fight for her survival.
- By Dead Rising 3 she had developed a gothic appearance. This is most likely an effect of being an illegal.
