Dying Like Animals/Analysis

The breakdown of these folks is almost An Aesop in itself:

Delusional and Apathetic

 * Bats: "Nothing's wrong." Bats are so blind that nothing can pierce their self-imposed Masquerade. No proof is strong enough to reveal the truth of the threat. Even if the threat were to expose themselves with a neat Power Point presentation about their plan, Bats would just ask where the cookies are. They'll take one look at the growing horde of evil Mooks and say that they're nothing more than a bunch of dim-witted pranksters, or—if the Mooks in question are very Obviously Evil—they may be simply "a gangon PCP". Comes from the phrase "Blind as a bat".
 * Butterflies: "Let's live like there's no tomorrow!" These party animals refuse to take action in the face of imminent disaster, preferring to keep playing around While Rome Burns. Having abandoned the notion of self-preservation, Butterflies resolve to enjoy the fun while they're still alive and kicking.
 * Crows: "All shall perish!" Crows are Obviously Evil types and see the new threat as just making their jobs easier, but are too short-sighted to see it also means their eventual downfall. They don't ever realize that if all the good guys are defeated, there will no longer be a fresh supply of carcasses for them to prey on. They'll be the type to pollute the water supply just to kill off those pesky heroes without considering where they'll be getting a drink from.
 * Lambs: "The Hero is taking care of it, so I don't have to bother protecting myself or even trying to avoid danger. After all, the hero will save me every time." Bats are blind, but Lambs have 20/20 vision and know the dangers very well. And yet, they walk right into the line of fire anyway, for any number of reasons, but always counting on the heroes to get them out of trouble when they get in over their heads. Saving them is what heroes do, right? This is particularly subversive in that many heroes seem to prefer it this way. Comes from the phrase "Like lambs to the slaughter".
 * Mice: "They're too powerful. We may as well give up." Mice are downers, often discouraging the hero from even trying to resist the Big Bad for fear of angering them. Occasionally this because they're also Suicidal Pacifists who abhor violence—even in self-defense! You can expect mice to be snitches for The Empire.
 * Ostriches: "If we hide/stay out of it, nothing bad will happen... at least, not to us." Ostriches know there's a problem and that no large group is responding to it, but they believe that ignoring it will make it go away. Yeah, tell that to the zombie of old Mrs. Withers. Comes from the old tale that Ostriches hide their heads in the sand, thinking that if they can't see the danger, it doesn't exist.
 * Reindeer: "Okay, this may be a problem, but do we really expect these freaks to save us?" Reindeer are more concerned about the heroes being their potential rescuers than they are at getting rescued. The heroes are still different from them and making their lives hell for that is what Reindeer live for. Unlike Rudolph, they'll often continue even after the hero saves them, because he's "noble" that way, no matter what they do to impair him. Comes from the behavior of the other reindeer in the Christmas carol "Rudolph the Red-nosed Reindeer".
 * Sheep: "Don't worry, I'm sure The Government knows exactly what to do." Sheep know there's a problem, but see no reason not to buy the government line of "it's fine" or to do something themselves. Surely that fiend raising The Legions of Hell can't possibly be a threat to the army. Interestingly, the more of these people there are, the more likely it is that The Government is actively involved in the Evil Plan.
 * Turtles: "We can outlast 'em easy from here." Similar to Ostriches, except that Turtles know that the enemy will still be after them once they go into hiding. However, they are confident that their infrastructures will hold and will defend them from the threat. It was always there, so they don't think it's their efforts that are going to save them as the Wolves below think. Also, it's their own safety measures they've inherited, not those put in place by the government. If it were the government, that would make them Sheep. Still, they underestimate The Virus and its capacity for getting to them. Comes from the idea that if a turtle hides inside the shell, he can survive being prey to a crocodile (but not a shark...).

Self Destructive

 * Mules: "Of course this scientific device won't cause the apocalypse!" The scientists who got everyone into the mess in the first place (For Science!) and refused to listen to any people warning them of the apocalyptic risks. Nearly always either the first or last to die, but it's always a Karmic Death at the hands of what they invented. Intelligent book-wise, but stupid when it comes to common sense (basically the polar opposite of Book Dumb).
 * Boars: "Come on, guys, we can take 'em! Let's get out the Torches and Pitchforks and we'll finish them off in a matter of minutes!" These are the brave, foolhardy souls who insist on sacrificing themselves for the greater good, even when they don't actually need to, much less help. Their courage may be admirable, but it usually causes them to get in the way of the competent heroes. Not to mention that it's hard to think rationally about how to defeat a Big Bad when you have an army of Boars squealing for his blood. Worse still is when the Zombie Apocalypse kills off the entire army and promptly turns all of them against the heroes as well.
 * Chickens: "Let's get out of here before it's too late!" Chickens' reaction to the mounting disaster is to try to put as much distance between them and it as they can. Chickens are often as selfish as Wolves, concerned only with their own safety and not with helping others escape. Their escape attempts might fail disastrously, and if they do reach their intended destination, they might find that the disaster got there first. Comes from the slang term "chicken" for a cowardly person.
 * Lemmings: "It's them! It's those terrorists the Benevolent Autocrat warned us of! Get 'em!" Lemmings are a special bunch: not only do they eagerly swallow the same load of bull the Sheep do, but they also try as best they can to help the Villain with Good Publicity catch the heroes. While they're less effective than Boars, they nonetheless hamper the hero, since he can't very well kill them, but they'll slow him down and maybe get him caught. You can expect any Love Interests the hero develops to have at least one Lemming for a friend, who promptly turns him in.
 * Rats: "I'm not sick! It'll all be okay if I keep quiet." They know they're sick (though they really don't want to admit it to themselves, let alone anyone else). They know they'll die and infect or kill their friends if they don't go away or bite the bullet. But they stay quiet and doom them all. Rats make The Virus's work easier by acting as plague carriers, much like rats and fleas during The Black Death in Europe.
 * Vultures: "These are my corpses to loot! Get your own!" Vultures are a more passive form of Wolf. They're less of a physical threat, but will steal anything that isn't nailed down or on fire (and they steal crowbars and fire extinguishers for the things that are), hampering The Drifter and other heroes by stealing his kit when he comes to help. Interestingly, vultures make for pretty good Side Kicks and Morality Pets, since one will inevitably be befriended by the hero after being caught stealing. Comes from traditional portrayals of scavengers like Vultures.
 * Wolves: "I said for years they'd come. Now they're here! What? Get your own shelter! Wait, you're one of them!" Wolves are determined survivors. They not only heeded the Agent Mulder's crazy ramblings, but also took them as gospel and prepared for the worst. Problem is, they're so paranoid and militant that they're likely to see any other survivors as competition and attack them or organize with other Wolves into formidable and hostile packs. They usually have something the Heroes need, but are nearly impossible to persuade to help voluntarily. Ironically, these guys are usually among the first to go in any survival-horror situation.

Opportunistic

 * Foxes: "Both sides are idiots! What an excellent opportunity!" Foxes are somewhat akin to Weasels in seeing the opportunities around. However, not only are they unafraid of the villains, but they are also savvy and quick enough to play both sides against each other, morality and ideology be damned. A Fox relies on his wits, his speed, and his charm to get him through, no matter which side wins, and if neither does, well, the Fox will still be on his feet after the dust settles. Unlike most of the others, Foxes can actually be quite useful or even helpful, if you can turn them to your side. Or if the villain betrays them. Or if you can persuade them there's more profit in your side winning. Basically, when in a capital-D Disaster, Foxes are your best bet. At least they're smart. Comes from the phrase "clever like a fox".
 * Weasels: "Get your anti-monster spray!" Weasels are just as scared as Mice, but they use the disaster to their benefit. They're the ones selling a gallon of bottled water for $50, cheap "protection from evil" medallions, rainmaking abilities, etc. Comes from the slang term "weasel" for a shifty person.

Sell Outs

 * Moles: "Trust me, there's nothing to worry about!" The Mole is, of course, the undercover villain who is not only forcing events along the worst possible path, but who is also likely to be encouraging all the other varieties to live down to their potential. Comes from the slang term "mole" to mean "spy", because this is a villain undercover.
 * Jackals: "Finally, we have a strong leader ready to put those malcontents in their places! Where do I sign up?" Jackals are like Lemmings and Snakes: they eagerly collaborate with the villain because they think his campaign of terror and genocide are just causes. Whether it's out of hate, fanaticism, or ignorance, they prefer the villain's despotism to a more benevolent regime. Usually, they're harmless once the villain is dethroned: their prejudice comes out only when the bad guys are in power.
 * Snakes: "Fight them? Why would I want to do that when they have so much to offer?" Snakes are a special case: they are just as able as the hero of seeing through the villains' ruse... and wholeheartedly supporting him. Whether it's for power, riches, or kicks, Snakes will join the biggest alpha predator's pack against the hero and help enslave their weaker fellows. In war movies, Snakes are the opposite of La Résistance.

Other

 * Scorpions: "I'm doomed. Better to end it before they torture me to death." These characters are usually found (and quickly die) in Crapsack World settings, or early in some horror movies as an indication that things will not end well for the protagonist. Scorpions are not suicidal out of depression or glamorizing death. They've discovered the world, or even just them, is slated for utter destruction or a fate worse than death, or they may have done it out of insanity from discovering something man was not meant to know. In short, they choose to die out of fear for a Fate Worse Than Death. Comes from the myth that scorpions will sting themselves to death when surrounded by fire.
 * Chimeras: "I know he's evil, but he just wants to make the world better. Maybe if we hand over the heroes he'll leave us be." Characters that blend two or more animals of different groups.
