Which Undertale Character Are You

Which Undertale character are you? Don’t you want to know which soul matches yours? This simple & Accurate quiz is going to reveal it by 20 questions.

An Odd to Undertale

Undertale is an RPG video game released in 2015. But the game is so amazing that it created a cult-like community around its characters and universe. You can find few indie games that could come close to Toby Fox’s fictional universe’s success.

Fans love this game so much that they filled the internet with fan-made content about it. “Which Undertale Character Are You?” is a type of quiz that roots in the desire of fans to relate to the characters and the story even more.

According to Steamspy, around 50 Undertale-related YouTube videos are uploaded each day! That is while the game released in 2015 without any major update or DLC to follow up.

We are talking about a Kickstarter project that took over the world in less than a year. And no one should ignore the beauty and magnificence of this tiny little world of monsters and humans.

Now, let’s see which of the memorable Undertale characters you are through a fun quiz that celebrates this masterpiece one more time.

Here Is an Undertale Character Quiz That Still Works in 2021

Fans won’t stop asking, “which Undertale character are you?” That is why you see so many online persona and soul quizzes relating to the underworld all over the internet. But the thing about most of them is that they are outdated. While the original game was published six years ago, the additional fan-made content never stopped popping up. And that is why our quiz is updated for 2021.

How Does It Work?

We wanted to create a Which Undertale Character Are You test that is fun to take. But the game is hard to compete with as it has so many cool features. So, we decided to make it a three-part Undertale quiz. The first part gives you some alternate encounters. The second part includes challenging decisions. And the last section analyzes your playstyle.

Alternate Encounters

During the gameplay of Undertale, you encounter many monsters (aka NPCs). Your character, Frisk, can engage in conversations with these souls and decide how to interact with them. You should do the same thing here on the Which Undertale Character Are You quiz.

We will create alternate scenarios and encounters, giving you multiple options to complete the dialogue.

Difficult Choices

You will never find the answer to “which Undertale character are you?” if you don’t make tough decisions. So, the second part of our quiz forces you to step out of your comfort zone. The choices vary from “would you rather” type of stuff to “fight or mercy” kind of options.


Undertale fans know that your playstyle affects the ending of the game. Depending on your choices, you might follow a pacifist, neutral, or no mercy path. So, our Undertale character quiz’s third part analyzes how you did or would play the game. It will help us discover your monster or human soulmate more accurately.

Which Undertale Character Are You After Finishing the Game?

Spoiler Alert: As soon as you finish the Undertale game with a pacifist attitude, you get an option to reset everything. The idea is that you can go back and do the opposite of everything you did in your first walkthrough. So, you could try killing monsters instead of giving them a chance to live. And that is when your actual character is exposed!

Our Which Undertale Character Are You quiz gives you the same option. We will be inspecting your choices throughout the test. So, even if you avoided the “No Mercy” path in the actual game, here you will face such a challenge again. And we believe that is the best way to find out your true Undertale character.

Here are some honorable mentions of the Undertale characters included in our quiz.

Frisk. Your soul might end up matching the protagonist of the story. But that is not necessarily a piece of good news! Frisk is an F-ed-up personality who can be brutal and kind at the same time.

Alphys. It would make many fans happy to know their Undertale character is Alphys. She is a shy, kind, and socially awkward monster that steals your heart right away.

Sans. If you match this guy, you are a popular person. Sans is probably the most beloved character of Undertale main story and Alternate Universes such as Underfell, Underswap, and Horrortale.

Flowey. Well, people who have the Flowey’s soul believe in the idea of “kill or be killed.” That makes them a bit of an aggressive and cruel person now and then.

Undyne. If this warrior girl monster is your Undertale character, you are a lucky person. Undyne is portrayed as a strong, passionate, and determined personality that even her body cannot resist her determination level—and that is why she melts before she dies (Oops! Sorry for the spoiler).

Asgore. You are neither a hero nor an antagonist. People whose soul matches Asgore are miserable good guys who have no idea how to deal with their past mistakes.

Or?… The Which Undertale Character Are You quiz includes more souls. So, you have the chance to end up with a surprise match at the end of the test.

The Results of the Undertale Quiz Include Shipping!

We have seen the fans asking, “Which Undertale character would kiss you?” That is why our quiz results include an answer to such questions to feed your curiosity. Shipping the video game characters has been one of the fanbase’s main interests since the very first day. And now you have the chance to see who would have a crush on you if you were living in the underworld of monsters.

How to Play?

Playing personality quizzes is straightforward: Choose the option that’s true about you—or you relate to—and select “Next.” Unlike trivia quizzes, personality tests have no right or wrong answers. But the questions are in forced-choice format. The point is to push you to choose an option that makes the most sense, not the one that’s 100% true. For the most accurate results, don’t overthink your responses. Go with options that you “feel” are the best.
