Suu (スー, ) is a Slime Girl that snuck into Kurusu's house without notice while looking for sources of water. She is the fourth girl to move in with him, albeit unofficially. Prior to her appearance Slimes were still considered fictional creatures by humans and, thanks to Ms. Smith not wanting to bother, are still thought of that way outside of the people she interacts with.

Notable Attacks/Techniques/Abilities:

  • Liquid Body: As her physical makeup is a liquid substance, her body acts in the same way. She can place people and objects inside of her body, or have them pass through. This makes her difficult to catch, as she can simply pass through the restraint, such as with Rachne's webs.
  • Invulnerability: Her physical makeup also makes her seemingly immune to any form of physical damage, as seen when Centorea's sword harmlessly passed through her. Even when she solidifies herself, she is still immune to any form of blunt impact, as seen when she used herself as a living shield to protect a girl from being hit by a truck.
  • Adhesive body: Suu also has the ability to stick to any surface, such as ceilings.
  • Poison and Disease Immunity: Due to her unique biology, Suu cannot catch any Human diseases. She is also capable of consuming any foods that could result in food poisoning to both Humans and Extraspecies, and even discerning what's poisonous and what isn't. The only side effects being that she develops a more abrasive way of speaking after eating poison and poisoning the liquid she spat at Draco.
  • Water absorption: As it's seemingly her only basic need, Suu is capable of absorbing water into her body. All she has to do is make physical contact with water and it will be absorbed. However, it's not clear if it happens automatically or if Suu can control it. Depending on how much water she absorbs she can also change her size and body proportions. She can also expel her internal water in pressurized streams from any part of her body. Suu is also capable of filtering her own internal water. Her breasts are capable of storing the same volume of water as a fish tank.
  • Absorptive properties: Suu's personality, appearance and even abilities can change depending on which substance she has recently absorbed, though over time she will return to normal. Taking in water that is full of minerals will increase her intelligence by a notable degree and make her speech more sophisticated, while taking in poisonous liquids will make her more rude and make bubbles come from her body and turns her purple. The water she expels also becomes poisonous as well. Likewise, taking in seawater will make her more mature (in both appearance and personality) and lustful. The most extreme example was when Suu absorbed a full tank of experimental fertilizer, which caused her to grow to gigantic proportions, made her seemingly more intelligent, grow extra hair tentacles and allow her to fire an "atomic breath" from her mouth.
  • Healing: Suu has shown that she is capable of curing at least a severe cold by having the sick person drink from her internal water. The exact process behind this hasn't been revealed. She can also heal simple wounds such as cuts by putting them in her mouth.
  • Shapeshifting: Suu seems to have an almost complete control over her own biology, which grants her shapeshifting powers that might even surpass that of a Shapeshifter like Doppel. For one, Suu can mimic the appearance of anyone, Human and Extraspecies alike. Suu's shapeshifting is so versatile, she can even transform into clothes or objects, like boxes. She seems to have enough control over her own anatomy that she can control her own solidity and texture, as seen when she transformed into clothes without making whoever wore her wet. Miia once thought of using this ability to have Suu be "worn" by Papi and Mero to disguise them as Humans. The disguises were capable of fooling Kimihito and Ms Smith. However, unlike Shapeshifters, Suu's shapeshifting has one major drawback: her antenna and signature eyes will always be visible. Also, repeatedly changing forms in a short time is exhausting for her. The slime that makes up her eyes stores the information she needs to imitate people accurately.
  • Size shifting: Suu changes in size depending on the amount and type of water in her body. The more water she absorbs, the larger (and more voluptuous) she becomes, with seawater having a more noticable effect. Also, with the absorption of certain products, such as a full tank of experimental fertilizer, she can grow to be giant size.
  • Voice-Mimicry: Suu is also capable of perfectly mimicking people's voices, though she hasn't used it in combination with a disguise yet.
  • Mind reading: When touching someone's head with her antenna, called her "Slime Feeler", Suu can view their memories, thoughts and emotions. Combined with her ability to mimic voices, it allows her to broadcast a person's thoughts to everyone in her area.
  • Fast learner: Suu also seems to be a fast learner, having learned to talk interact with others in few days, and later on is able to mimic her friend's word-for-word in order to help them "talk" with Kimihito while he was sick, and eventually started speaking on her own.
  • Miscellaneous: Suu has no need to breathe.

Key: Normal Suu | Giant Suu (after absorbing industrial strength nutrients) | Suuzilla (anime only)
