Whew, this one took a while to get a proper reference for. Honestly, this is one of those sona ideas that you just think about and go "Yeah, I could dig it." Honestly, I've been thinking about this since quite a couple conversations between myself and  Ipsum , especially about the interactions slimes have the world and especially between fellow slimes. So, here's a slimesona. A physically shapeshifting slimesona that can mimic just about anything in shape and a fair bit of size. Usually holds a human male form with fair features, a slightly athletic build, and curly hair, or what's shaped like curly hair.

Consider this a personal slime form, I guess.

This piece was done by  TechSupportGirls and I'm quite grateful to have it done.

Like I said though, he loves physical shapeshifting. This means that he can modify his body to do just about what he wants in a physical sense. If that means something like moving his head to sticking out of his stomach or having an eye on the end of his palm, or changing his physical composition completely, he can do that. Normally, the consistency of his body is jelly-like, meaning that it had a fair bit of give if you push on it, and can jiggle a bit sometimes if his body is in a semi-solid state. Body shape, color, etc, he can change them all. He's a bit of a slacker, but also at the same time fun to be around as he likes to simply enjoy good company, but isn't always the best at maintaining it.

Malcolm is formless, ageless. What is known about him is that he is an exceptionally curious individual whom has been around for a very long time. He was formed from the grey matter of a great scientist whom wished to experiment with the various fluids of the body and see if any could viably be used to create artificial lifeforms. Interestingly, the chemistry worked in his case, and yet with this, the creativity of the human mind and more was given form through a slime. To be honest, this is something that he doesn't talk about. Not due to a foul experience of his creation, but instead due to his curiosity leading him to not dwell on that matter for long periods of time. Considering what he was born from, it's remarkable to consider that he actually is limitless in what he can utilize his body for. All the initial things you would consider a slime to do and more, for certain, but creativity and curiosity are his primary attributes. Shapeshifting, gendershifting, intellectual pursuits, languages, rapid learning, sound composition, and so much more are within his reach to utilize.

For all intents and purposes, he can shift himself more fluidly than most other slimes, and it lends itself to a variety of situations and instances in which he learns quite a lot, and he uses that information for future interactions. A living, learning creature.

Malcolm generally holds a masculine human male appearance, somewhat modelled after the grey matter he originated from, but this is more a default form held when interacting with others. Things like growing more body parts and such are not out of his reach to do as a slime. His default body color is also not really static either, he just uses one based on his environment and such. The one thing about him
that does stay static is some aspect of his eyes. He is prone to keeping his eyes green, no matter what colors he takes on.

His body structure is set up in a layered format. An external layer and an internal layer, which both perform separately or uniformly. This is usually most often noticeable when he changes body color to a certain way, allowing his internal layer to be more visible. This internal layer is more or less his core, but it's indeterminable exactly what is fueling him or how he survives, because of how relentless he can seem at times. In reality, it's more than likely that he thrives off of knowledge, and that's what keeps him going.

Malcolm's personality is indeed curious and creative. He has understanding of concepts such as personal space, privacy, money, art, and much more. His long life has led to him understanding many things, yet because of his nature, he's prone to brash first impressions. He's more likely to simply just be there rather than taking the time to introduce himself. A full-on slave to curiosity and a hunger for knowledge, but also completely willing to hold a conversation if need be.

He's a bit hard to describe in that way, because of how complex that leads him to be.
To be honest with you, his past and his present are things that really are passing in nature as he doesn't dwell on them. Perhaps at some point, I will expand on it, but he doesn't seem too keen to, so I won't for now.

He absolutely loves music, especially any type of music with heavy beats or high bpm, anything that can make his body vibrate.
