Mad Dummy, later known as Mad Mew Mew in the Switch version, is a supporting antagonist in the 2015 indie RPG Undertale.
She is a ghost monster that lives inside a dummy in the Garbage Dump and the other dummy's cousin. She tries to kill the protagonist to avenge her cousin, regardless of what their actions are.
Appearance[]
Mad Dummy is a ghost inhabiting a standard training dummy, resembling a beigeish-orange cotton humanoid with no limbs, an elongated nose, and a stand that acts as support. Her stomach splits open, revealing a toothy mouth. Compared to the standard dummies, the Mad Dummy's eyes are more detailed, having actual sclera instead of the regular dot eyes. It is unknown what the actual ghost that possesses the dummy looks like.
As the Glad Dummy, the dummy she inhabits turns yellow, and her eyes revert to the standard dot eyes. She gains prominent blush.
Due to swapping bodies, Mad Mew Mew is substantially different looking than her previous form. She is a pale cat girl with green eyes, pink hair, and two tufts of hair on both sides of her head. She wears a pink and white frilly dress, and bells are attached to her collar, her tail, and on both of her ears. A speaker is hidden in her chest, and despite inhabiting a doll, she is able to contort her face to make a variety of expressions, with most of her original expressions using prominent eyebrows to signify anger. In the overworld, two alternate costumes swap out her pink clothes for blue or white.
Personality[]
The Mad Dummy seems to be somewhat psychotic, wanting to avenge her cousin even if the protagonist does nothing to them. She seems to hate to feel powerless since she felt disarmed when her dummies don't kill the protagonist quickly. She also often repeats herself at least three times and maniacally laughs often.
Despite her psychotic nature, she seems to be calm and collected at times given that she can cooperate with some other people and she does leave Frisk alone after Napstablook interrupts their battle and she serves as Undyne's punching bag for training outside of her home. Additionally, it's implied that Mad Dummy harbors a crush on Undyne, but doesn't act on it as by the time she becomes Mad Mew Mew, Undyne and Alphys are already in a relationship.
When the Mad Dummy turns into Glad Dummy on the Genocide Route, she becomes so angry that she becomes corporeal with her dummy, making her happy and thankful to Frisk, so if anything, the Mad Dummy just needed to let off some steam.
She also seems to care about her cousin, but she might be a little overprotective considering that they still attack the protagonist even if they do not do anything to them.
Biography[]
Pacifist/Neutral Routes[]
When the protagonist is about to leave the dump in Waterfall, the Mad Dummy encounters them. She reveals that her cousin possessed the training dummy from the beginning of the game. No matter how the player interacted with the dummy earlier in the game, the Mad Dummy is enraged and attacks the player.
She intends to steal their soul, and after failing to kill the protagonist, the battle is interrupted by Napstablook, ending the battle, and the Dummy leaves.
She is later found outside of Undyne's house. If the True Pacifist Route is completed, the Dummy apologizes for its actions by calling herself a dummy. If the protagonist talked to her at least once during her battle, the Mad Dummy calms herself down by just a little. Otherwise, she changes her name to "Angry Dummy".
Genocide Route[]
When encountering Mad Dummy in the Genocide Route, the amount of hatred directed towards the protagonist's actions allows her to "fuse with her body," fulfilling her lifelong wish. As a reward, she is willing to spare the protagonist as soon as combat begins. Unfortunately for the newly-renamed Glad Dummy, she is now vulnerable to physical attacks. The player then has the option to spare or kill the Dummy. If they kill her, the Genocide Route continues, if they spare her, the Genocide Route is aborted.
Nintendo Switch Version[]
In the Nintendo Switch version of Undertale, after the battle with the Dummy, she finds and possess a limited-edition Mew Mew animatronic doll from somewhere around Alphys' lab. Seeing it as the perfect body for her, the ghost tries to fuse with it, yet fails to do so. For some reason, she decided to head over to the Dog Shrine under the skeleton brothers' sink in order to hide away.
After defeating Mettaton EX, the protagonist can enter the doors to Mew Mew. They can either fight or touch the doll. If the doll is touched a certain amount of times, a fight can start. Deciding to use her unbridled rage as a catalyst, Mad Mew Mew eggs on the protagonist into attacking her in order to feel angry enough to fuse. Unfortunately for her, Mad Mew Mew starts realizing that anger alone isn't enough to help her fuse, and asks the protagonist to show her what "LOVE" feels like. From there, the protagonist can either spare her or destroy her new body, and as such either making her a friend or causing her to vow revenge on the protagonist someday.
After her fight, she can appear outside of Undyne's house in the True Pacifist Route, and in the credits, Mew Mew replaces the Dummy. If her body was destroyed, she will continue living on with pure fury, but if she was spared, it's stated that she's "Meowing Into Primetime", suggesting that she's become a star on the surface.
Seeing as how both the Xbox version of the game has her in the Mad Mew Mew body despite not being fought in that form, as well as the unused Alarm Clock dialogue referring to the character as Mew Mew, the ghost becoming Mew Mew is the definitive path for her character, at least in the Pacifist Route.

Trivia[]
- It is implied that the Mad Dummy is also one of Napstablook and Mettaton's cousins according to an entry in one of the diaries found in Mettaton's home.
- Her Deltarune alternate universe counterpart seems to be living alongside Napstablook and "Mettaton" (who hasn't become a robot yet and thus is using a different, unknown name), confirming that every single ghost monster in the game is related.
- If you include the Switch version of Undertale, Muffet and Mad Mew Mew are the only two mini-bosses with their own SOUL Modes.
- Despite caring for her cousin, she doesn't seem to know their name.
- The Ruins Dummy, Napstablook, and Mad Mew Mew are the only encounters whose fights can end violently without averting the True Pacifist Route, due to none of them being able to die, and as such cannot give EXP.
- In a similar vein to her cousin, Mettaton, she's implied to be more comfortable in her Mew Mew body than as a ghost/dummy, going as far as calling it "the perfect body" for her. In the True Pacifist ending, if you won her battle via fighting her, she says that despite being in pieces, she still has to "be herself."
- This makes her the only character in Undertale to be confirmed as Transgender (or at least symbolic of the transgender experience), going from their assigned "agender" at birth to female. That said, Mettaton going from his ghost form (which should similarly be agender) to his robot body can also be interpreted as a gender transition.
- A snippet of Mad Dummy's boss theme Dummy! can be heard at two different parts of Spamton NEO's boss theme BIG SHOT.
