Kwaku Anansi was a very clever spider.
In order to obtain the power of storytelling from Nyame, the Sky Father, Kwaku had to apprehend three evildoers.
He tricked Mmoboro into a gourd, tied Onini to a stick, and lured Osebo into a pit. As a reward, Nyame gave him the gift of storytelling and imagination. Kwaku stored his powers in a spider-shaped amulet, which was used by many after him, including the legendary hero Anansi.
The trickster Anansi recently made his appearance in Justice League of America, issues 21-26, in a story arc written by Dwayne McDuffie, who also created the Static Shock version. This version lives inside Vixen's Tantu totem, and is the source of her powers. Though at first it is unclear whether he is benevolent, it turns out he merely tested the Guardian of the Totem.
