Baboons

Baboons are hideous creatures. While most species of monkeys are friggin' awesome, there is always going to be some exceptions this particular rule. In this case, the exceptions are baboons. These hateful, ugly monsters are known for their big, blooming red asses and huge fangs. Seriously, they actually have fangs. These disgusting primates are usually found in Africa. Baboons can also be found in various zoos across the world.

In the 1976 horror film The Omen, Katherine Thorn decided to take her darling baby Antichrist, Damien Thorn, to a zoo in London, England. As they drove through the monkey habitat, a voice over a loudspeaker warned them that "the boons" were dangerous, and that they would be advised to keep their windows rolled up. Didn't matter much though, because these animals instinctively sensed that there was something off about this kid and attacked the Thorn's car in droves. Katherine freaked out while Damien remained pretty chill in the car. Fortunately for them, bot mother and son emerged from the affair unscathed.

In the 2007 werewolf film Hybrid, a scientist named Andrea Hewitt came up with a process involving eye transplant surgery. In addition to restoring the affected person's eyesight, this process had the added benefit of endowing them with some of the donor's aptitudes. In one experiment, she gave a baboon the eyes of a tiger. As if these monsters weren't loathsome enough, you gotta go and give 'em cat eyes. The baboons in question eventually managed to get out of their cages and made a complete mess of the entire laboratory.
