Katejina Loos (カテジナ・ルース Katejina Rūsu) is a character and an antagonist from the Mobile Suit Victory Gundam TV series. She is voiced by Kumiko Watanabe.
Katejina is a strong-willed seventeen year old girl from Uwig who was a pen pal of Uso Ewin. Separated from her parents around the time of the destruction of her home town by the invading BESPA forces of the Zanscare Empire, Katejina joins the League Militaire with young Uso Ewin. However, Katejina disapproves of the League's reliance on Uso as a Mobile Suit pilot due the mounting toll on his young body and mind.
Katejina is captured by Lt. Cronicle Asher and taken to the Zanscare Empire where she becomes Cronicle's personal assistant. Later, she trains as a soldier, eventually becoming a mobile suit ace. It is during this period that her attraction to Cronicle, and hatred of Uso begins to grow. Her personal support for Maria's matriarchal ideals, her annoyance at Uso's continual attempts to interfere with what she views as her true happiness, and her sheer admiration for Cronicle turn her into a dangerous Zanscare loyalist. She and Uso battle on several occasions, where she succeeds in killing several members of the Shrike Team and Odelo Henrik in the process. However, she ultimately loses her memory and what appears to be her eyesight while fighting Uso during the Battle of Angel Halo. After Cronicle is defeated by Uso in the Battle of Angel Halo, Katejina returns to Earth to live out her remaining days in peace.
- Despite his predilection for killing off several main characters during the final phases of his shows, producer Yoshiyuki Tomino allowed Katejina to live, saying "life was a heavier punishment for her."
- Katajina Loos can be seen very clearly in the second episode of Mobile Fighter G Gundam, she reacts in shock to Domon's sudden attack on Chibodee.
- In the Mobile Suit Victory Gundam novelization, which follows a different interpretation of the original TV series, Katejina is badly burned during an attack and is retrieved by Chronicle for medical treatment at a Zanscare Empire institute. There she undergoes an operation at the Super-Psyco Research Institute and is transformed into an Cyber Newtype. In the novel, she is ultimately killed in battle with the LM313V10 Second Victory Gundam.
- Katejina served as both a "Navigator" for players and also piloted the Gottrlatan unit in Mobile Suit Gundam: Extreme Vs. She and Haman Karn were the only two Navigators in that game to pilot a unit, and were carried over to the follow-up, with Nena Trinity being a third Navigator that was selectable.
