3W

3W is the future great-granddaughter of Arthur Read. She lives in the future and was seen in the opening and ending of "Background Blues". Like D.W., she can sometimes be careless and annoy her brother, R4.

Physical appearance
3W wears futuristic clothing: a cream sleeveless dress, a pink long sleeve bodysuit, yellow jetpack, and a blue belt with a yellow belt buckle. Her hair is in the same style as D.W.'s, except that 3W has a widow's peak.
