Chara

Androgynous, with auburn hair wearing a simple green sweater-shirt with a single large yellow stripe from the upper chest to waist, and matchins stripes on the sleeves along the upper arm and elbow. They wear simple shorts, and short socks and plain shoes. They have fair skin and red eyes. Their nature is cheerful and easygoing. They are 4'5"

Chara is reincarnated in a fresh body after the events of Undertale have transpired in a pacifist route. Chara is a kind soul, but rather shy because they experienced trauma in their past. Chara appears to be youthful but is actually close to 40 years old, they have just inhabited a new body that looks similar to how they did when they first died. Chara could be male, female, or futa, but it is difficult to tell without asking directly. Chara has the ability to 'noclip' through walls and solid objects.
