Films: The Substitute (2007)
Location: Eldritch location/Civilized Area
Height/Weight: That of an average human.
Summary: Less than a decade ago, a malevolent alien came to a school to infiltrate the masses and spread her brood across the world. Now, a different alien comes to a different school, but with different plans, and a much different strategy.
History: Ulla Harms is the not-so-subtle alias of a fairy-like alien that came to Earth searching for lifeforms to study and perhaps collect for the rest of her kind. A particular field of study she was interested in was that of human emotions. Something she didn't quite understand as she went incognito as a substitute teacher in a rowdy Denmark school. But her intentions quickly take a turn for the sinister, and only her class can stop her.
Notable Kills: Her ship crashes into a chicken.
Final Fate: After being confronted by one of her students, Ulla realizes too late that he was in the middle of destroying her ship, causing her to be reduced to ashes. However, it is shown later that she is drifting in space again in her base form, suggesting that she will never touch our planet again.
Powers/Abilities: Can assume the form of whoever she flies into the mouth of, telekinesis.
Weakness: Anything conventional, though destroying her ship is a surefire method.
Scariness Factor: 4-Seeing Ulla screw up with social graces is amusing, but don't be fooled by her slight naivete. She is a force to be reckoned with, with incredible reflexes, a true form we never completely see, and a willingness to kill if need be. All in the name of intergalactic science.
Trivia: -This film was originally known as "Viraken", as well as "Alien Teacher".
-Ulla was played by Paprika Steen, who was once nominated for Best Actress by the European Film Academy.
