Tenchi Muyo Wiki
Tenchi Muyo Wiki

In the Tenchi Universe continuity, like the other characters, Washu's background is different from her OVA counterpart. Washu is still the greatest scientist in the universe, but she was banished from the Universal Science Academy for producing weapons of mass destruction capable of destroying countless planets, and was imprisoned in a capsule device which itself was encased in a large crystal, and sent into space. Eventually, the capsule fell on Earth and was placed in the Masaki Shrine where Washu remained for 700 years. That is, however, until she is freed during a squabble involving Ryoko (who is not her daughter) and Juraian princess Ayeka. Washu is not a goddess, being portrayed more as an egotistical mad scientist than in the official continuity, but still possesses her aloof, witty, and all-knowing nature.

Washu Universe

Washu with A and B.

Humorously, Washu has two dolls named A and B that pop up on her shoulders to proclaim her greatness and to cheer her on ("Washu, you are a genius!", "You can do it, Washu!," etc.).

Washu, near the end of the series, talks with Tenchi, who was depressed as his grandfather was easily defeated by Kagato. Washu informs the downtrodden Tenchi that she has sensed enormous power and potential coming from him ever since she first met him and is able to convince him that he will be able to defeat Kagato because of his Jurai power surpasses his grandfather's.

In the final battle, Washu, unable to get the Juraian Army to cooperate with the extended Masaki clan, then disables a portion of the Jurai fleet with her supercomputer virus. After the battle with Kagato, Washu was elected honorary president of the Universal Science Academy, promising to only use her powers for peace. She was kicked out a month later for developing a weapon capable of destroying the entire universe (though as Tenchi narrates, no one was surprised). Washu eventually returned to Earth along with the other girls.

Washu is instrumental in saving Tenchi in Tenchi Muyo! in Love. She is able to shield Tenchi from fading away from existence because of the assassination of his mother in the past and sends the other girls to the year 1970 to protect her from the sinister Kain.

In the final installment, Tenchi Forever!, Washu searches far and wide for the missing Tenchi and when he is finally found, she is able to harness enough power from Camellia trees around Japan in order to defeat Haruna, the woman keeping Tenchi in her dream world against his will.

It would seem that like the OVA version, Washu is in the form of an adolescent girl. It is unknown if this is her own doing or just the way she naturally is.


  • The movie, Tenchi Muyo! Daughter of Darkness. and the series, Ai Tenchi Muyo!, both have tenuous connections to Tenchi Universe, but are their own distinct continuities and Washu's depictions in each can be found in the Other Spin-offs tab.
