Because not a day goes by without someone here at Cracked fantasizing about punching an animal, we felt particularly well-suited to answer this question (which we posed to provoke fantasies about punching animals). What follows, then, is a study of the five animal species best poised to take back this planet from us. Here we shall discuss their strengths, their weaknesses, and how, if push came to shove, these species would fare against an elite team of Humanity Marines in a battle to control the world.

So it's only in the past couple decades that scientists finally got around to looking at octopuses, at which point they found out that they're actually pretty smart. Spookily smart. Because it'll eat most things smaller than itself, the average octopus has got a whole mess of different hunting techniques it uses to capture the various prey. They're tool users, nest builders, and presumably pretty good blackjack dealers. And they've got excellent memories; scientists have taught octopuses all sorts of tricks, like disassembling LEGO models, opening locked cages, and solving mazes.

Less charmingly, they can all use these memories to hold grudges. There's a case of an octopus scientist (octologist?) that a particular octopus took a particular dislike to, possibly because she messed up a complicated octopus handshake ritual. The octopus hated this girl so much that any time she walked by his tank, he'd spit on her. She disappeared for a while, because who's got time for that, only to return a year later to find that, yes, the octopus recognized her, and yes, he was going to keep spitting on her.

"This is my Tank and I am the Law and I am the Lash."

If that doesn't sound so bad to you, like if you don't live next to any octopus tanks, well, just know that they can move around pretty good on land, too. In captivity, they apparently leap out of their tanks all the freaking time, at which point they scurry along the ground like all the nightmares ever. Octopus scientists (octometrists?) have found them behind desks, on bookshelves, and in teapots. Also, some of them are shape-shifters, meaning everything around you right now could potentially be an octopus. If you didn't plan on sleeping this week, say hello to the mimic octopus:

Yeah. So, octopuses are intelligent, tool-wielding, shape-shifting grudge holders, and the only reason they haven't attacked us yet is because to them, we don't taste very good without being deep fried either. As soon as they master boiling-grease technology, humanity is on notice.

Mission Log, Operation: Terror in the Deep

Zeke: I don't like this, Sarge.

Sarge: You don't have to like it. You just have to do it. We have to get these eight-legged SOBs back for what they did to Buenos Aires. That's why we're taking the fight to their home.

Frenchie: But our guns! They don't work underwater.

Biscuit: I'm also getting sand in my mask.

Sarge: Get back in formation, Private Biscuit.

Biscuit: But I dropped my mask. Wait. Here it is.

Zeke: Biscuit? BISCUIT!?

Biscuit: Oh God it wasn't my mask it was a shape-shifting octopus oh God HAAAAAAAALP!

Sarge: Shoot!

Frenchie: We can't!

Sarge: Then kick him! Kick him in the head!

Biscuit: IT'S IN MY HAIR IT'S IN MY HAIR IT'S IN MY HAIR.

Weight: not so big

Terrain: Africa, South America, Asia

Special Powers: strength, numbers, strength in numbers

Population Available for Military Service: numbers do not go up this high

"Army ants" is a description of a few different species of nomadic ants that move and hunt in massive colonies, sometimes numbering millions of ants at once.

How many grad students had to die to complete that census?

Army ants are also, happily, completely carnivorous, and with millions of them in one place at a time, they essentially never stop killing, tearing through hundreds or thousands of prey an hour. They only stop killing for a few weeks a year, but don't relax -- that's just because they take a breather to make more army ants.

They're clever, too, moving by day in a variety of formations to protect the more valuable members of the colony, and to drive and trap their prey before them. Witnesses have observed army ant waves 65 feet wide. And at night, the ants stop, forming a colony out of their own bodies, full of tunnels, passageways, and public spaces, filled with what still must surely be a tremendous amount of murdering other species.

They can turn cow corpses into skeletons, and yes, have already been known to kill humans, although for now it's just been the slowest and weakest -- people unable to move out of the way of the relatively slow-moving columns. But don't take too much solace in that, because they can move underground, too. And were they to ever organize on a scale larger than a few million, that could change. Because boy howdy, there are a lot of them. In terms of total body mass, all the ants on Earth may outweigh all the humans, and when you consider just how enormous humans are getting, that amounts to a whole lot of ants.

Mission Log, Operation: Zergling Rush

Zeke: Feels quiet.

Sarge: Last civvies evacuated yesterday, Zeke. After what those six-legged SOBs did to Kuala Lumpur, no one's taking any chances.

Frenchie: Listen! Zey are coming!

Sarge: Eyes up, team. Wait. Where's Biscuit?

Zeke: He went to go take a leak.

Sarge: Biscuit, get back on the concrete right now!

Biscuit: What's going on ... OH GOD NO!

Frenchie: Zut alors!

Sarge: Shoot!

Zeke: We'll hit Biscuit!

Frenchie: And our bullets! They are too big for the leetle ants!

Biscuit: THEY'RE IN MY HAIR THEY'RE IN MY HAIR THEY'RE IN MY HAIR.

Why are they so deadly? Well, they'll attack just about anything that gets too close to them, with no provocation (other than "existing too close to them"). Humans, cars, trucks, whatever. They'd probably run down a tank, but no one's been willing to risk one of their tanks yet.

Also of note, along with being the size of cars, they, much like cars, are not brought down by casual gunfire. Their bones are so big that they are essentially bulletproof when shot at with many smaller calibers. It takes massive, thumb-sized bullets to take them down, and even then, often more than one; Cape buffaloes have been known to sprint away after taking grievous wounds. And not just to go wander off and die somewhere. No, getting shot just seems to piss them off. Cape buffaloes are notorious for leaving blood trails and circling around on the people hunting them to try and take them down from behind.

That's right. While wounded, they use themselves as bait, in a trap that will result in them frontally attacking a truck full of people carrying small artillery pieces. They do not take shit from anyone, and were they ever to organize themselves militarily, or even just stop standing still while we carefully aim at their brains, humanity could be in a lot of trouble.

Mission Log, Operation: Cow Patty

Zeke: Here they come.

Sarge: Frenchie, get up on the 50. As soon as they get over that rise, you give them hell.

Frenchie: With plezure. Come get some, you bastards. This is for Gretchen and Claude and Flaubert and all the others from Marseille.

Sarge: Good. Biscuit, you deployed that razor wire in the alley behind us, right?

Biscuit: Is that what you asked me to do? Oh man. That makes so much more sense than what I did.

Sarge: So the alley behind us isn't a mass of razor wire?

Biscuit: No. I built a high shelf and put the stack of wire up there.

Sarge: What? Why!?

Biscuit: I thought you wanted to raise it. Like to stop bears from eating it. I don't know.

Zeke: They're coming from behind us!

Biscuit: Sorry, guys, that's on me.

Sarge: Brace yourselves!

-A massive impact rocks the Humvee. Frenchie falls from the roof turret-

Zeke: Frenchie! Are you OK?

Frenchie: Non!

Zeke: They're on the roof!

Sarge: It's OK. This is armored. We'll be safe here.

Frenchie: Merde!

Zeke: He's right!

Sarge: They're pooping on us! They're pooping in the turret!

Biscuit: IT'S IN MY HAIR IT'S IN MY HAIR IT'S IN MY HAIR.

Also of note, they've fully earned the adjective "wandering," given their propensity to roam into all sorts of places humans would rather they not be. Houses, cars, log piles, boots, clothes, your nightmares. They're particularly well-known for hiding in and around banana plants, forming a particular health hazard not just to people involved in harvesting bananas, but also to people who simply like to eat bananas, when they chance upon a saucer-sized spider in their bananas. They've even been known to show up in banana shipments sent as far away as England.

That's right. We're dealing with an enemy that has already mastered international smuggling.

And if upon hearing this news you still eat a banana without a gun carefully trained on it, you are a liar or a fool.

This spider's particular venom is a highly potent neurotoxin that causes paralysis, asphyxiation, and death, and just because these spiders are dicks, blinding pain. Also, just for fun this time, the venom seems to cause massive erections. So you're not even leaving a very elegant corpse behind.

So, if they are highly venomous, like to sneak up on people, can travel the seas, and give their victims death boners, how is it we're not living in silos right now while the Brazilian wandering spiders roam the surface? Well, it turns out that scientists have determined that these spiders don't always inject their venom when they bite humans. These imbeciles have concluded that we can thus relax, when even the tiniest bit of thought would actually conclude that we should panic immediately, as we have proof that the bastards have been holding back. Clearly, the Brazilian wandering spider has been biding its time, waiting to distribute adequate numbers of themselves around the world via banana shipments until they have enough to launch a massive simultaneous strike on humanity's command structure.

Mission Log, Operation: Suspicious Banana

Zeke: London. Washington, Tokyo. All gone.

Sarge: Keep it together, soldier. We've got a job to do, and these six ... eight? Whatever-legged SOBs are going to pay.

Biscuit: I don't know if they're really SOBs, Sarge. I think the bigger ones are actually female. They'd be daughters. I guess they'd be DOBs.

Sarge: Private Biscuit, what the hell is wrong with you?

-A klaxon sounds, echoing throughout the base-

Sarge: All right, everyone. Get dressed. We move in five.

-They get dressed. Everyone watches nervously as Private Biscuit puts his helmet on, without incident-

Zeke: Huh.

Biscuit: What?

Zeke: That seems odd. Am I wrong?

Frenchie: No, I thought that, too.

Biscuit: What's everyone staring at?

Sarge: It's nothing. Keep moving, people. These many-legged daughters of a bitch aren't getting past us today.

Biscuit: Oh no! My boot!

-Private Biscuit leaps into the air, dropping his boot, which is crawling with spiders-

Sarge: Shoot them!

-They shoot the spiders-

Biscuit: Holy crap! Thanks, guys.

Zeke: Huh. I guess that's ... OK.

Frenchie: It does feel like we are missing something.

-Private Biscuit takes off his helmet to wipe his brow. The ceiling collapses above him, sending spiders cascading down into his hair-

Zeke: There it is!

Biscuit: WHY HAVE YOU FORSAKEN ME, HAIR-GOD?

Native to Northern Australia, Papua New Guinea, and countless sweat-soaked nightmares, the brown tree snake is perhaps most famous for its work on the island of Guam, where it is considered an invasive species. On Guam, with none of its natural predators around, the brown tree snake has essentially taken over the entire island. On an island about 30 miles long, there may be 2 million of them.

On the surface, an individual brown tree snake is not that dangerous to humans, as its venom isn't that deadly. On Guam, though, they're considered a serious nuisance. Given the sheer number of them, at any moment one of them is probably crawling on some electrical equipment, causing it to burn out. That's right. They're prodigious breeders, experts on island-hopping warfare, and they have considerable experience attacking our infrastructure. Also, and this cannot be understated, THEY ARE SNAKES THAT LIVE IN THE TREES.

"Hello again! Wait! Why's everyone running and peeing themselves?"

How much trouble is humanity in? Well, in yet another case of good news that is actually the worst news possible, scientists report that the population of brown tree snakes on Guam is actually decreasing. They figure that the snake has exceeded the carrying capacity of the island.

Which means this island-hopping, fast-breeding snake-o-war is motivated to move.

Mission Log, Operation: Death from Above

Biscuit: I'VE GOT A BAD FEELING ABOUT THIS ONE, GUYS.

Sarge: Calm down, Biscuit. We're going to be OK.

Biscuit: I DON'T KNOW, MAN. I AM FREAKING OUT.

Zeke: I think he's right, Sarge. I don't think we should have brought him.

Sarge: We need every man we've got if we want to avoid what happened in the entire Western Hemisphere.

Frenchie: But, sir. Taking Biscuit into the woods? He is not handling this so good.

Biscuit: AMAZING GRACE, HOW SWEET THE SOUND, THAT SAVED A WRETCH LIKE ME.

Sarge: Keep it down, Biscuit. You'll give away our position.

Zeke: There! In the trees!

Biscuit: AAAAAHAHAHAHAHAHHAHA!

-The entire squad fires wildly into the woods, snakes falling everywhere, just a carnival of violence-

Sarge: Hold your fire!

Biscuit: AAAAAAAAAH!

-Private Biscuit shouts and spins, dry-firing his rifle in every direction-

Sarge: Biscuit! Get a hold of yourself! We're OK. We got them.

Zeke: Look at the markings on this one. It's the Snake Commander. We got them. We did it!

Frenchie: Formidable!

Sarge: You did it, Biscuit. I'm proud of you.

-Sarge gently tousles Private Biscuit's hair-

Biscuit: THEY'RE IN MY HAIR THEY'RE IN MY HAIR THEY'RE IN MY ... derp.

-Private Biscuit goes into a catatonic state and never recovers. Later, a statue of him is erected in the Eastern Hemisphere. As he would have wished, the statue was made bald.-
