|Major Spoiler Warning|
This page contains major spoilers that have not yet appeared in any episodes anywhere worldwide.
In concept art, Anansi is brown-skinned and muscular with golden brown hair. As seen in preliminary sketches, her hair appears to be in dreadlocks tied back into a ponytail.
In concept art, Anansi wears a yellow tank top with white edges and a black spider design on the front. White bandages wrap around her hands and wrists, and she has black elbows pads. She also wears yellow shorts, which have a white upper band with a name in black capital letters on the front and two horizontal black lines wrapping around the rest, two black downward-bent lines on each side of the shorts, and white edges of the shorts' legs. Beneath her shorts are black short leggings.
One preliminary sketch of Anansi showed her wearing orange shorts, white sneakers with blue socks and what appear to be shin guards, and a small blue shirt with a small spider drawn on the left side. Another preliminary sketch showed the spider design covering her whole shirt, which suggests that she may have an alternate form as a hero or villain. In one sketch, her name was shown printed on her belt as "Anansi" and in another sketch as "Nancy". One sketch showed no spider design, and featured stars on her shorts.
- Anansi's name comes from the African folktale character of the same name.
- In African folktales, Anansi often takes the shape of a spider and is considered to be the spirit of all knowledge of stories.
- Anansi's existence was first teased in an earlier tweet by Thomas Astruc, where he asked the question, "Afraid of spiders?"
- On a computer screen in a photo of production by Jeremy Zag on his Instagram, there is an unfinished reference model of Anansi.
