Films: Nezulla: The Rat Monster (2002)
Location: Haunted home
Height/Weight: That of an average human.
Summary: It is rather odd how full of killer rats the early 2000s were. But no matter how many swarms come our way, none of them can seem to top the sheer power and horror of just one rat. A rat-man, sure, but still a rat.
History: The result of a Japanese-American facility trying to craft the ultimate disease-immune super soldier, Nezulla is the worst that unregulated animal testing can do. After he slaughtered most of his creators, he kept inhabiting the ruined building. Unfortunately, his mere presence spreads a deadly plague that's choking an entire town to death. Now, a group of soldiers are sent to take out Nezulla and perhaps find a cure via his own flesh.
Notable Kills: Murders a soldier after scaring him with his spear-tail in a matter quite similar to a specific Xenomorph kill from the original "Alien".
Final Fate: After an intense brawl with the survivors, Nezulla gets a grenade shoved into his mouth by one of them. Although he tears off his arm in the process, his head is blown off, and after a bigger explosion destroys ground zero for the bacteria, his DNA is used to cure all individuals of the deadly plague.
Powers/Abilities: Nezulla has cunning intellect, can spread a deadly disease for miles, has a carapace that can deflect bullets, has a spear tail, and is adept in hand-to-hand combat.
Weakness: Anything from the inside.
Scariness Factor: 4.5-Nezulla may look a bit top-heavy, but that doesn't make him any less terrifying. Aside from his ghastly appearance, which shows how nasty tokusatsu suits can be, he very nearly killed an entire town without even having to go near most of them. And you can't even take out this mangy rodent with simple weaponry.
Trivia: -Nezulla's stock-sounding roars are often achieved via mixing the roar of a lion with that of a human.
-Rats are actually said to have an intelligence almost on par with humans. They are capable of displaying a wide variety of emotions, can outsmart a lot of man-made traps, and are very sociable.
