Chara is a human with brown hair, pink cheeks, and red eyes (their eyes were originally brown). They wear a green jacket with yellow pockets, dark grey pants, red sneakers and a rainbow colored scarf that was originally owned by Asriel. They might also own a faded ribbon, since monsters cannot hurt them, but that is not confirmed.
Chara is a kind-hearted soul that loves their brother. They always prefer to be called "cool" rather than cute. They might also have a short term memory, since according to the creator they also have played every route except for genocide, but they always forgot every run they have played. They love to garden, cook, bake, and use magic, just like their parents. They also love animals, mostly dogs, as they owned a ton of pets.
