5 Terrifying Serial Killers Who Happened to Be Animals

There are three theories as to what caused this sloth bear's insatiable hatred for human beings. Some say it was a mother sloth bear avenging her murdered cubs in the grizzliest fashion imaginable (we're not even sure if that was a pun or not). Another local legend claims the bear fell in love with a girl and was taking vengeance on the closed-minded villagers who kept them apart. Or maybe a painful injury simply drove the animal to madness.

Whatever the cause of the sloth bear's rampage, it came to an end when Kenneth Anderson, a professional writer and monster hunter, shot the creature in the chest. Sloth bears aren't traditionally difficult to hunt, but Anderson had to make three separate attempts to stop the sickle-fingered face-eater.

The Time: 1991 to today

The Place: Canada to Orlando, Florida

Once upon a time in Sealand, a Canadian water park, there was a killer whale named Tilikum, which means "friend" in the Chinook language. Stick with us, the irony will set in shortly.

Tilikum was 11 years old and weighed a strapping 12,000 pounds. He was a perfectly friendly, trick-performing gigantic whale, with enough charm and personality to disarm everyone who worked with him. By all accounts, there was not one shred of malice in his flippered body. That is, until one day he dragged a female grad student underwater after she fell into his tank.

Tilikum blocked the panicked woman from exiting his tank and tossed her body around with his two female tank mates. The girl was killed, but since this was his first offense, Sealand chalked the killing up to a terrible accident and didn't hold Tilikum accountable.

Sealand eventually went out of business, and Tilikum was moved to SeaWorld in Orlando. He won over that community as well with his tricks and his charm, and seemed every bit the fun-loving performer he was before. Then in 1999, an irresistible opportunity wandered into the park. That opportunity was a 27-year-old homeless man who sneaked in after hours to visit his favorite whale.

What happened next is open to speculation, but by the time the park opened the following morning, said homeless man was found lying dead and naked on the whale's back. Almost as if he was posed that way.

Two mysterious deaths weren't quite enough to negate the giant stacks of money whale-watchers forked over to watch Tilikum perform tricks on a daily basis. He stayed at SeaWorld, and another 11 years passed without incident. Then, in February 2010, in front of a packed crowd of 5,000 people, Tilikum threw a wet fart into the face of subtlety and snatched his trainer off of dry land.

Eyewitness reports differ, but depending on who you believe, Tilikum either pulled his trainer into the water while she was rubbing him down or leaped up and snatched her while she was standing near his tank. All the reports end pretty much the same way, with Tilikum drowning his trainer for no reason. The report also goes on to deliver the immortal quote "The normally docile whale had killed twice before," suggesting that they are perhaps unclear on the meaning of the words "normally" and "docile."

As of March 30, 2011, Tilikum is still performing at SeaWorld.

We all know elephants are capable of killing if they have to. They're gigantic and intelligent, so we're not at all shocked when one manages to kill a hunter or rampages through a village in search of food. But they're hardly violent creatures; we think of them placidly wandering around the shores of a river, spraying water on each other with their trunks and dropping poops the size of a tractor tire. It's impossible to imagine an elephant hunting anything, let alone human beings.

Yet for two years, a single male Asian elephant terrorized the villagers of Sonitpur, killing at least 27 people. The locals named him "Osama bin Laden" for reasons that are not abundantly clear.

Being much bigger than any person, Osama preferred trampling or goring people to death. In one six-month period, he ran down 14 people in separate incidents. He also destroyed homes and businesses, melting back into the surrounding wilderness whenever search parties came looking for him. It wouldn't have mattered much if they could find him, though, because he reportedly had no fear of firearms. Picture the climax of Scarface with Babar instead of Tony Montana.

After two years of carnage, the government issued a "shoot to kill" order for Osama, though to be honest the fact that such an edict had to sit in the legislative oven for 730 days raises serious concern. He was finally caught outside of a tea estate and shot to death by a licensed hunter. But, in true Opera/Red Dragon fashion, there is substantial doubt as to whether or not that hunter killed the right elephant. Which means Osama bin Laden (the elephant) could be anywhere right now. Even right behind you.

The Time: 1999

The Place: Birnin Kudu, Nigeria

As a general rule, it's true that snakes -- even venomous snakes -- are more scared of you than you are of them. After all, they tend to be tiny and quite vulnerable to shovel or boot-based attack. However, as small, unassuming psychopaths throughout history have proven, you can be comparatively weak and still poison the shit out of anyone.

One such snake, a cobra with a chip on his shoulder, went on a 10-day killing spree in the city of Birnin Kudu. While most snakes only strike when threatened, Cobra Commander just balls-out rushed people, one after the other. Humans may be big, but most of us have pretty terrible situational awareness once we're suddenly shot full of poison by a tiny, fast-moving animal, so the little bastard was able to strike and disappear like Solid Snake (pun absolutely and totally intended).

According to reports, the Nigerian Ankle-Biter (as we have officially named it, just now) "would appear suddenly, strike a victim before disappearing, only to reappear to bite yet another." There was no warning, and no discernible reason for the attacks beyond "screw you all for having legs."

As it turns out, Birnin Kudu has a major problem with overgrown weeds, which provided our venomous mass murderer with the means to sneak up on a vast number of victims. The government has since gotten a hand on its "killer" weed problem, which seems to have cowed the rapacious snake for the time being. However, somewhere on the outskirts of town, there is still a mass-murdering poisoner with a taste for blood and a kill count in the double digits.

The Time: 1907 to 1938

The Place: The Indian subcontinent

For a brief period in modern history (about 1907 to 1938), nature tried to stage one last hurrah against humanity by unleashing a bizarrely coordinated assault by the big cats of India. Among them were the Leopard of the Central Provinces, the Leopard of Rudraprayag, the Leopard of Panar, the Champawat Tiger, the Thak man-eater and the Tigers of Chowgarh. All of these predators went batshit banana sandwich crazy at roughly the same time, suggesting some cosmic alignment or contagious insanity or maybe just something in the freaking water. Whatever the cause, these cats all shared a sudden, mighty need for man flesh.

The Champawat Tiger alone was responsible for 436 documented deaths in Nepal and Himalayan India, which, for those of you keeping track, is more than any human serial killer in modern history.

This cat attacked during the day, while the Leopard of Rudraprayag attacked at night, sometimes busting down the doors of its victims like goddamned Leatherface and dragging them screaming into the darkness. All told, more than 1,200 men, women and children were killed by 33 big cats over the course of three decades, establishing a legacy of terror that has yet to be equaled.

The killings might have continued unabated were it not for this man:

Over those 30 years, Col. Jim Corbett of the British Indian Army was repeatedly dispatched to personally "resolve" the problem animals. He was able to bag all 33 of the murderous felines, starting with the Champawat Tiger. See, that was back in the days when any good project's first step was "Kill a tiger."
