"The Gel upgrade." Samus said, selecting the upgrade. She had just finished rearranging the room in her fit of power, and was currently recovering from the rush of aggression and extreme physical dominance that came with it. Since she hadn't found many yet, Samus was pleasantly surprised when it turned out to be a power suit upgrade, and quickly inserted it into her suit.

Samus waited a moment, and her suit glowed brilliantly, turning almost white in a brilliant shine, before ending abruptly, leaving Samus without any armour, and for some reason completely naked, missing her zero suit. Samus looked around her bare body for what had happened to her suit, feeling a strange weight in her chest, much heavier than usual. After a quick inspection of her body turning up clean, Samus noticed that her skin had a very shiny, almost rubberlike quality to it. She also felt strangely light for some reason, and saw a blue tinge go over her skin, spreading quickly over the rest of her body, her skin becoming smoother and even shinier. Samus held up her arm to see what had happened, and gasped in surprise as she saw through her hand! Her arm had gone transparent, the blue colour turning deeper and richer as it took on a goo-like appearance, the rest of her body following suit. Samus began to run towards the mirror, but found her steps short, and the room seemed to get larger every time. Samus looked down, and saw that her legs were melting into a puddle of slime! The melting reached her waist, and Samus flailed about, trying to move as she slowly melted into just a puddle of slime.

A minute later, after Samus had calmed down from the process of melting and realised that she could still see, tried to move her eyes around, her field of vision sliding around the puddle. She realised that she still had control over what was now her body, and imagined herself as she was before, fully human and normal. Her body began to from together, rising up to form one mass, shaped like on Samus Aran. Having regained the use of her limbs, Samus took a wavering step forward, her foot slipping apart as she desperately willed it to stay together, and took another, slowly getting used to the odd feeling of her slime body, and made it over to the mirror, her body becoming more and more cohesive with each passing moment. She looked at herself in the mirror, and examined her changes.

She was made of a bright blue shiny gel, slightly transparent, and every one of her features was smooth and blue. Her face was arranged and looked the same as before, but when she opened her mouth she lacked a throat past her mouth, and her eyes were simply an indentation that looked like them, despite still being where she could see. Her genitalia were gone, smooth orbs and lines where they used to be, making her appearance naked, but not indecent. On the back of her head her gel had arranged itself to look like her hair, one blob that acted like a very stuck together form of her ponytail.  But in her chest, she found the source of her heavy feeling. A small glowing orange core shone from her chest, seeming to be where her armour went, and what kept her cohesive and together.

Samus tried to manipulate her body, sprouting an extra arm and controlling it perfectly, reducing herself to a puddle and back, stretching and compressing into various shapes, manipulating the general shape of her body. The only limitation seemed to be that her core needed to remain in contact with the rest of her, and she was unable to move it out of her slime anyway. She also found that she didn't need to concentrate to hold her human shape, it seeming to have set itself as her default shape.

"…" Samus said, what was her mouth flapping uselessly. "…!" Samus attempted to yell, still entirely silent, lacking any vocal chords or anything to form the sound.  

"…!" She attempted to yell again, trying to figure out how to form vocal chords and lungs.
