Washu Hakubi (白眉 鷲羽, Hakubi Washū?), the self-proclaimed greatest scientific genius in the universe, is a fictional character in the anime and manga Tenchi Muyo!. Her character differs depending on the continuity, though she sometimes displays a number of innate powers which she rarely uses, preferring to solve problems with reason or technology. In all incarnations, Washu has also shown to be somewhat prudent and is generally trickier to fool than Tenchi or the other girls, which makes it harder for her to fall into an enemy trap. In all three Tenchi series Washu had also created an inter-dimensional laboratory in the closet of the Masaki house, although her laboratory is a lot bigger in the OVA series than in both of the TV series.
The name "Washū" is an ancient one for Japan; specifically, the region around Osaka. The name "Hakubi" was derived from the name of a train line, the Hakubi Line. When translated, Washū means "eagle-feather", and hakubi means "excellence". Washu's hair is derived from a costume from Noh plays, intended to resemble the (usually black) legs and claws of a crab. For her, it's a red crab, because this is a food specialty of Osaka. As such, the red crab logo appears on much of her merchandise and miscellaneous apparel.
