Eight total strangers that were all within the same bar when the zombie infection hit Raccoon City. The eight of them join forces to fight the outbreak.
Kleptomaniac Hero: In lieu of actual characterization, there are hidden SP Items throughout each scenario in both games, five of which in each level are unique to your current character. Most of what's known about the Outbreak cast comes from their reactions to the SP Items, which basically comes down to what they thought was neat or interesting enough to take with them.
A police officer who attempted twice to become a member of S.T.A.R.S. but failed. He's cheerful and brave, but somewhat irresponsible; he keeps cheap liquor in the fridge at the RPD, and his bar tab is apparently huge and well overdue. Kevin was a member of the unit Leon was set to join, and they only met each other once, but are amicable with one another.
Badass: Just watch his ending where he stays in the city with Jim because they are infected.
Kevin: "Now... let's finish this like men."
Cowboy Cop: He applied for S.T.A.R.S. twice and got rejected due to his happy-go-lucky personality, and was on the verge of becoming a desk jockey due to that.
Irony: If you play as David, AI Kevin will not help you or listen. If you play as Kevin, AI David will also be spiteful. Doesn't stop the shippers, though.
Lightning Bruiser: Kevin is the fastest character and has the second most health, but compensates for this by having a comparatively short virus gauge. Even on low difficulties, Kevin's real enemy in levels like "Decisions, Decisions" is the clock, as it's very easy for his virus gauge to run out before he reaches the final boss fight.
Noob: Kevin was pretty much the newbie-bait character. If a Kevin showed up in your online game at all, he would be a complete load about 90% of the time.
The game even recommends that Kevin is for beginners.
Alyssa is a reporter for a local newspaper in Raccoon City, and an acquaintance of Ben Bertolucci's. She begins the game with a stun gun, which can inflict startlingly high amounts of damage at close range. She's a physical fitness fanatic, and her SP items that don't have to do with journalism are usually health food or exercise gear.
Action Girl: The most battle-oriented among the three female characters.
Too Awesome to Use: The stun gun can only be reloaded with a battery, which is a relatively rare item; its only other use is as a component for David's stun rods or time bombs. When it's fired, the stun gun instantly makes zombies crumple to the ground, but its real advantage is that it'll drop charges into an enemy at high speed as long as you hold down the button. You can empty it into a larger enemy in seconds.
Useless Useful Non-Combat Abilities: Alyssa carries four lockpicks that can be used to open various doors, drawers, and cabinets, but it takes forever unless you choose the right pick. There's no way to tell which is the right one and it changes in every scenario, difficulty, and instance.
What Happened to the Mouse?: If you play as anyone but Alyssa in "Flashback", she will be at the starting point of the scenario, but wanders away as you leave the cabin. On Easy/Very Easy, she can be found near the bridge to the hospital, claiming she's too tired to continue, and will give the player her taser. On Hard/Very Hard, she's become a zombie and attacks players on the forest path.
A waitress at J's Bar, Cindy is very kind, putting others' needs before hers. She carries an herb case that allows her to carry a massive amount of medical supplies, and starts a scenario with enough herbs in the case to make two 100% mixed herbs. Cindy can duck attacks, allowing her to completely avoid almost any injury if you time it right.
Back Alley Doctor: She's not The Medic because George gets that title being the main doctor, but her carrying herbs make her at least this.
The Chick: In practice, Cindy's just as capable as any other character, but she's the most chick-like of the lot.
Her SP items tend to be beauty products, cosmetics, and "cute" things like dolls or a frilly apron.
Dropped a Bridge on Her: If you play as anyone else but Cindy in "Wild Things", she will appear at the starting point of the scenario. However, after the cutscene after the zombie elephant makes its appearance, she's shown to be dead when the game resumes.
Mark is a veteran of the Vietnam War, and currently employed as a security guard. Fortunately, his wife and son live outside the city. Mark is overweight but very strong, and can move objects by himself that would usually require two people, and can rear back for a more powerful melee strike. He has the most health of any survivor and has the ability to block.
A Friend in Need: He has a mini-storyline with Bob in "Outbreak" which progresses if the player has Mark guide him along with the rest of the group to safety. It's all for naught because Bob will either commit suicide or become a zombie.
A plumber who keeps to himself, David is very reserved and silent.
Blood Knight: If you press the emote button after a boss fight, it becomes clear that David is not actually having that bad of a time with all this. The exceptions are the two possible bosses from "Wild Things," which he doesn't like having to kill.
Knife Nut: When equipped with a knife, David can swing four times in succession if you push the button with the right timing. The fourth strike is a powerful backhand swing that knocks enemies flying. In File #2, bringing four David-types to spam the fourth hit is the "knife-wall" strategy, and was the most common way to cheese the last battle in "Desperate Times."
Mr. Fanservice: David C in File #2 is just wearing a pair of leather pants with no shirt or shoes, and he lets his hair down. The women who played Outbreak didn't seem to use any other character or costume.
Mysterious Past: Little is known about him, but several of his SP Items in the first Outbreak indicate he was a juvenile delinquent.
What Happened to the Mouse?: If no one is playing as David in "End of the Road," he's briefly shown leaving the starting area. In the event the players end up leaving the sewer through the street exit, they'll find David lying dead nearby.
A subway worker, Jim relies on his good luck to survive. Jim is capable of playing dead, which makes enemies ignore him as long as he stays flat on the ground. Unfortunately, while Jim is "dead," his virus gauge skyrockets.
Ambiguously Gay: What with that highlighted hair and wimpy attitude. He also collects shoes.
Lethal Joke Character: Jim begins the game with his lucky coin. Flipping it and getting "Heads" permanently increases his critical hit rate by 15%, which stacks up to three times. If you get "Tails," however, it returns him to the standard rate. Standing around and flipping the coin until you hit "Heads" three times turns Jim into one of the single most dangerous combat characters in the game, particularly when armed with a lead pipe.
Jim's other lucky coin, which he begins with in File #2, gives a small crit bonus to any character holding it, and extends the durability of melee weapons.
When he's on the ground, Jim's virus gauge shoots up as if he's been incapacitated through damage. This can be temporarily stopped with anti-virus pills, however. More importantly, when Jim goes to play dead, he throws himself to the ground in a headlong dive, which is sometimes a more useful defensive move than playing dead would be by itself. Jim was considered a very strong character for speed runs because of this.
The Smart Guy: He's good at solving puzzles, and is usually seen carrying some crosswords.
A kind doctor and recent divorcee. He manages to remain calm and polite even under stress. George's hobbies include hiking and collecting watches.
Dropped a Bridge on Him: If no one is playing George during "Decisions, Decisions," he can be found outside the entrance to the university's subway station with a fatal injury. He dies after speaking to the player and is surrounded by several healing items.
Genius Bruiser: George can launch a more powerful shoulder tackle than any other character, which makes him (of all people) the most powerful unarmed combatant in the cast.
Kleptomaniac Hero: Almost every SP Item George gets in the first Outbreak has something to do with wristwatches, which makes it look like he's obsessive-compulsive.
A former Umbrella researcher, Yoko witnessed the attack on William Birkin and tried to get the hell out of town. Unfortunately, she didn't see the outbreak coming and wound up trapped.Yoko has the lowest health of any survivor, but her virus gauge climbs the slowest and she's got a backpack that gives her another four item slots. She also has an evasion move that, while initially seeming useless, gives her an enormous invulnerability window.
And Then Yoko Was a Zombie: If you select any other character but Yoko in "Below Freezing Point", she will appear at the starting point. After the cutscene with Monica, you later find Yoko in the control room as a zombie; how her death occurred is unknown.
Dark and Troubled Past: She was employed as a researcher for Umbrella, and was even experimented on in the development of Tyrants.
Difficult, But Awesome: Yoko is the slowest character and has the least health. Her dodge is the best in the game, however, and the extra four item slots from her backpack count for a lot. Once a player learns how to master the dodge, particularly in conjunction with the quick-turn, Yoko becomes very potent. With proper preparation, she can solo bosses that any other character would struggle with.
An Umbrella Scientist, Greg created the Thanatos Tyrant. Not wanting the corporation to mass-produce it, he began a plan to betray them, first by commissioning a Raccoon University Researcher to create a vaccine. Later, he unleashed Thanatos, who proved a grave danger to both the Umbrella Biologic Countermeasures Service and the Raccoon City survivors.
Mad Scientist: For a split second, he sounds reasonable, when talking about how much of a disaster the T-virus project was. Then he starts rambling about how bioweapons must be "beautiful, unique, and godlike".
A renegade scientist working for Umbrella, Linda is making plans to escape the city when the survivors encounter her. She holds the key to curing the T-Virus, if she can be successfully brought out of town.
Video Game Cruelty Potential: In the last part of "End of the Road," if you rescue Linda but don't give her a hand, she slowly limps after you. It is possible to use her to detonate landmines.
White Sheep: Linda remains the only example in the entire series of an Umbrella researcher or scientist who isn't at least a clinical sociopath. She's genuinely helpful at all times, the obstacles she puts in your way are not her direct doing, and her survival is a net positive for both your characters and the world.
Another Umbrella scientist, Carter is a little too enthralled by the sheer power of the Tyrant.
Early-Bird Cameo: His model is recycled in "Below Freezing Point" as a survivor found in Birkin's lab.
Hoist by His Own Petard: You can't really accuse Carter of being stupid, or even malevolent; using the Tyrant to punch a way out of the labs is actually a halfway decent idea and it works up to a point. The problem is that he just won't shut up about his admiration for the Tyrant's raw power, right up until it crushes his skull.
In the wake of the attack on William Birkin, Monica murdered several of her former co-workers at Birkin's laboratory and tried to escape with some of his discoveries. It didn't go well for her.
Dark Action Girl: Was this close to escaping Birkin's laboratory, and lasted a good while in the outbreak while murdering her former co-workers along the way before her demise.
Karmic Death: She ends up getting killed by the project that she's killed several people to get.
A short blonde patrolwoman with the RPD, Rita is one of the last surviving cops in the building.
What Happened to the Mouse?: Rita always survives the "Desperate Times" scenario, which is highly unusual for NPCs in Outbreak, and is last seen in the back of the speeding RPD van with the other survivors. She isn't mentioned again, and her escape from Raccoon City is possible but unlikely.
Regan headed into the woods with her daughter Lucy in an attempt to escape Raccoon City, and ended up trapped inside a cabin as mutated insects invaded the forest.
Lost Forever: As Regan is part of the Illusion Ending scenario in "Flashback," it is now very difficult to find or unlock her.
What Happened to the Mouse?: She and her daughter were last seen taking shelter inside Ed's old cabin in the woods. It's possible they survived, or that they were eaten by giant roaches.
