Nega-Suu

Black Suu is a giant Black Slime that stowed away aboard a cargo container ship to Japan. Upon discovery, the President of the Black Lily Advanced Materials Laboratory attempted to transport her to his facilities without the government's notice but a chance encounter with Suu saw Black Suu escape her transport truck and enter the water canals around Tokyo. An aggressive and stronger slime, Black Suu found Suu's unique experiences desirable and intended to draw Suu to her and absorb the younger slime's body into her own; eating the smaller slime's core to gain her experiences and abilities.

Physical Traits

 * 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.


 * Poison expulsion: After absorbing poison, Suu can expel it out of her mouth in a stream with a good deal of force, paralyzing those that get hit by it.


 * 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.

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. A similar event happened when Suu absorbed a bottle of a Honey Bee's Royal Jelly, causing her to once again grow to giant sizes.
 * 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.


 * Conscious digestion: Suu can choose whether or not whatever falls into her to be digested or not, this way, when a member of the house falls into her the only danger they will face is the threat of drowning. Any organic material (liquid or solid) can be dissolved and absorbed.


 * 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. One method she displayed was by breastfeeding Kimihito like a baby, while secreting her internal water through her teats in his mouth. The exact process behind this hasn't been revealed. She can also heal simple wounds such as cuts by putting them in her mouth.

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.
 * 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. She can even form nipples to secrete her own water. 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.


 * 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.


 * Slime Tentacles: The two tentacles that are part of her "hair" are actually prehensile appendages. They can grab things, absorb water and perform tentacle rape. They might be more useful than her hands, as those are not that strong due to a lack of muscle and bone.


 * Sense of taste: Suu's mouth is only ornamental, but she will choose to consume food or items from there if she wishes. Suu's sense of taste seems to be more of a survival ability. While she is only slightly affected by poison, Suu was able to identify edible plants from poisonous ones. Because of this, she has no problem eating food that tastes absolutely disgusting, such as Miia's cooking, or things that aren't considered food. However, on episode 6 of the anime series. Suu is shown with the others to be suffering from the effects of Miia's cooking( though she can digest Miia's cooking no problem, it's possible that certain chemical mixes within Suu might cause side effects/lack of nutrients). Another example would be manga chapter 34, where Suu is shown drinking a bucket of fresh cow milk, quoting that the milk was tasty. This leads to believe that Suu does posses a sense of taste, however her other body traits as well as digestion of harmful material may lead to believe that her taste is meant for survival purposes. Suu can eat for pleasure though, when in manga chapter 35, during Kurusu's banquet restoration, Suu ended up eating several dishes of seafood cuisine. Because the location was a hotel resort near the ocean, its most likely that Suu ate the food simply because it was delicious.


 * Voice-Mimicry: Suu is also capable of mimicking people's voices, though this is done through the combination of copying the person's general attitude, mannerisms, and raising or lowering her voice as necessary. In the anime it's shown that while her voice may not sound exactly the same, there is no question to whom she's speaking to of whom she's supposed to be.


 * Mind reading: When touching someone's head with her antenna, called her "Slime Feeler", Suu can view their memories, thoughts and emotions. She can vocalize the subject's inner monologue in real time, allowing her to broadcast their true thoughts and intentions to everyone in her immediate 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.


 * Eidetic memory: It's implied Suu may possess eidetic memory, as she was capable of perfectly memorizing and mimicking everything that was said and demonstrated to her when Kimihito was sick.


 * Acting: Suu seems to be a convincing enough actress that she can fool everybody around her into thinking she's not as smart than she actually is.


 * Miscellaneous: Suu has no need to breathe.


 * Weaknesses: Despite all these strengths, Suu is not invincible. Throwing her in a body of water can temporarily immobilize and stun her, as she becomes diluted. If the body of water is large enough, like a lake, the dilution effect would be strong enough to kill her. Heavy rain is also dangerous to her, as the impact of all the water drops dissolves any part of her body exposed to it.


 * Also, exposing her to higher temperatures dries her out. If she dries out, she shrinks in size, to the point where she can fit in a small bucket, and makes her lose her humanoid form. However, doing so is the equivalent of starving her, and during that time Suu will mercilessly molest anything with even the slightest trace of moisture on them, no matter the circumstances.


 * Additionally, due to being a living liquid, she is also susceptible to freezing temperatures.
