Welcome to the Yandere Simulator Mary Sue Litmus Test. Sometimes, RPing with a character that is "too perfect" is an unpleasant experience. Maybe they steal the spotlight from your OC, or maybe they overshadow them by being better at everything. That character is often called a "Mary Sue" on this wikia.

The Litmus Test is primarily for fun, but can vaguely measure how much a character fits that description too. I'd recommend an OC review by a fellow wiki user over this test, since a human can undoubtedly give a more accurate review, so you can interpret your results on this test how you will.

This test is heavily based off the Original Fiction Mary Sue Litmus Test, but with some extra things added to fit the universe. This test was contributed by Porcy. If you have any questions, feel free to ask him.

How to Take the Test

Every question on the test will have a number attached to it. These numbers represent points.

Method 1: Pen and Paper

  1. Grab a pen and paper.
  2. As you read through the questions, for every question you answer "yes" to, mark the attached number on that piece of paper in tally marks.
  3. When you've gone through the entire test, compare the amount of points you have to the results.
  4. Some questions may contain a negative value, in which case you can subtract that from your final score.

Method 2: Calculator

  1. Grab a calculator.
  2. As you read through the questions, for each question you answer "yes" to, add the attached number into the calculator.
  3. If it says "-number points", then subtract that number in the calculator.
  4. When you've gone through the entire test, compare the final number on your calculator to the results.


  • Do not add any points for questions about things you cannot control (e.g. if a ton of other users made their OCs have crushes on yours and you had no way to stop them).
  • Remember, not all of the traits in the test are Sueish on their own. It is possible to make a demon character, for example, and still make them balanced and interesting.
    • Think of them as spices. Add too much and your food tastes like shit, add too little and it tastes bland. Add just the right amount, and your food tastes delicious. Same with OCs and these sorts of traits.


  • Do not lie, or cherry-pick specific questions to answer. Answer every single one 100% truthfully no exaggeration, or your score will be inaccurate.
  • Every single time I have ever seen a debate over whether or not a character is a Mary Sue, the critic says "This character has a 200 on the test!" while the creator says "I got a 4!". This is the result of exaggeration, like I mentioned before.
