Films: Deep Blue Sea (1999), Deep Blue Sea 2 (2018)
Alias: Makos, Bull Sharks (Bella)
Location: Ocean/Haunted home
Height/Weight: Twice that of average makos.
Summary: Sharks are quite the smart predators when they want to be. Many even travel in schools because they know how much stronger they are in numbers. The same doesn't apply to the Mako shark...until science did things to its mind...
History: It was a crazy idea to begin with. Because sharks apparently never get cancer, a research facility in the middle of the sea has been studying and altering the brains of Mako sharks to see how they can cure Alzheimer's Disease. Unfortunately, their experimentation has led to the Makos becoming larger, hungrier, and much smarter. So much that they figured out a way to destroy their confines so that they may munch on the people and escape into the ocean to become top of the food chain.
Notable Kills: Sam Jackson's infamous death mid-speech. But before that, the sharks flood the facility by ramming a gurney with a still-alive person into the glass like a battering ram.
Final Fate: The Makos are shocked, blown up, and all pretty much destroyed along with all the research. No new experiments ever since...until many years later, when idiots decided to boost the intelligence of bull sharks, leading to a group of them led by a mother named Bella. They're still around, by the way.
Powers/Abilities: Highly increased intelligence.
Weakness: Anything conventional.
Scariness Factor: 3.5-Some of the bad CGI (especially in the sequel) gets in the way of much scares, but dear God, they knew which shark would scare us the most. A mako is bad already with those jagged teeth, but now we have ones with the coloration of great whites and the minds of killers. The bull sharks are fine.
Trivia: -No movie, sharks aren't immune to cancer. But they do get it at a drastically lower rate than humans do.
-Apparently, the final girl at the end was supposed to deal the final blow on the sharks in the first film, but test audiences hated her character for starting the whole mess so much that they had her killed off.
