Ryo-Ohki

Ryo-ohki is a creation of Washu created from the life form, Mass, and an unknown mineral source. Her purpose is to serve as the space transport for Ryoko. Ryoko, under Kagato's mind control, used Ryo-ohki to destroy dozens of planets until she was destroyed by Yosho. Over 700 years later, Ryo-ohki was revived by Ryoko to crash land Ayeka's ship into Earth where she was destroyed again. Ryo-ohki reproduced itself into a cabbit and is mostly seen playing with Sasami or trying to get carrots, her favorite food, from Tenchi's carrot crop. She assisted Tenchi and the gang in stopping Kagato and Dr. Clay. After assimilating with the Masses-formed woman, Ryo-ohke has the ability to transform into a humanoid version of herself.

Ryo-ohki has three forms she can change into: her cabbit stage, spaceship, or a humanoid. Ryo-ohki can even create dozens of other copies of herself as well as generate an energy blast in both her cabbit and spaceship forms. She has a telepathic link to Ryoko. Ryo-ohki can also phase through walls but it takes her two or three times most of the time to phase through a wall. In her human form, Ryo-ohki is having trouble learning to walk as she currently takes the form of a toddler to learn how to walk in the form.

Ryo-ohki has the characteristics and physical appearance of both a cat and rabbit. Nontheless, she seems to show the most care for Tenchi and Sasami. She's mostly seen sitting on top of Sasami's head or trying to sneak into Tenchi's carrot patch to get carrots. She can get quite giddy whenever there are carrots, usually putting Ryo-ohki in unusual situations as she will do anything for carrots.
