Reccoa Londe is the AEUG's top spy in Mobile Suit Zeta Gundam's opening. She seems to take Kamillle Bidan under her wing as he becomes more accustomed to being both a resistance fighter and a mobile suit pilot.
She also has a running romantic - involvement with Quattro Bajeena. She has a tortured past, and because of Quattro's indifference to her feelings for him, she eventually defects to the Titans under the charismatic spell of Paptimus Scirocco.
She is mainly the pilot of the Methuss, as well as supporting in multiple other suits, but she later becomes the pilot of Scirocco's prototype Palace Athene.
