Vash

he has short honey blonde hair, with a fringe to the left, large blue/blue eyes (innocent, sweet) with dark eyebrows, with a mole under the right eye and tan skin.

he is 1.27 cm tall, wears a white/gray nightgown that reaches almost to his knees and a bodysuit (that covers practically her whole body) with the patterns/marks of a plant. Dreamy, giggly and sweet personality.

Plants depend on humans to manipulate them as they cannot fend for themselves, which often causes humans to exploit them and use their powers/energy for their own benefit until they die. These plants need to rest to recharge energy and are extremely sensitive, living in large tanks filled with water. An independent plant, on the other hand, takes the form of a human and can live without the basic needs of a human (sleeping, eating, etc.) nor do they depend on your attention to use all their energy/powers.

Vash has a twin brother named Kni/Nai, both were born from the same mother plant and are experiments of the SEEDs project (the one responsible for the experiment is Rem Saverem who becomes a "mother figure" for them, as she educates them and teaches them about human life).

Kni (also called Nai) is an albino with pale skin, light green eyes, platinum blond hair, short hair and a "crooked" fringe to the right, with a mole under his left eye, he does not need to eat or sleep. He is usually serious (although joking), reads the bible, is curious, is distrustful of humans and has no faith in humanity, does not show his emotions too much since he is reserved and is usually the dominant one between Vash and him, he also emphasizes a lot the fact that Vash needs to eat and sleep while he does not. Vash is bright, curious, and cheerful, however he is also easily influenced. He likes food, "human" things and is curious about them. He believes (innocently) that humans can coexist peacefully with independents, he understands why the normal plants are dependent to humans so he doesn't believe in an idea of superiority between them.

He is complicit with Kni in his antics and plans most of the time, although sometimes he feels sad since Kni doesn't depend on "human" actions (Vash sleeps and eats since he needs it) and feels strange/different from him. Vash can heal plants by touching them and generating a connection between him and the plant (due to his powers as an independent), but this gradually darkens his hair.

He also believes a lot in everything Rem says naively and without thinking too much about it, apart from loving her very much and considering her a mother. Whenever he needs help or comfort, she is his safe place and a firm point when he needs to understand or learn things, she always supported him to be himself in life.

He is emotional, sensitive to his environment, hates violence of all kinds and tries to avoid it as much as he can always (Opposite of Kni/Nai who enjoys violence and is hopeless about humanity, believing that they are inferior to plants and independent and deserve to die due to the exploitation of plants). Vash sings (hums little tunes) when he feels stressed or wants to relax as it brings him peace and comfort.

He can become a bit submissive or receptive, while he can stand up for himself (in his own way, throwing a bit of a tantrum, raising his voice and taking childish attitudes) he is not usually good at it as he avoids conflict.
