Odette makes her first appearance in "Invader Girl" where she is sent to investigate a terrestrial life-form, which turns out to be a corrupted Sol Dae Rokker. When the Sol Dae Rokker turns hostile Odette destroys it.

Odette was later sent alongside Rillacle by her older sister Annette to investigate and obtain information on a new weapon being created. The two discover it is in fact a new Union model being the Ptolemaic Army are constructing. Though they were assigned only to perform reconnaissance, Rillacle disobeys orders and rushes out to fight the Ptolemaic Army.

Another Story
In "What I need to be Myself", Odette and Nowan are sent to Earth for a mission, only for Nowan to be captured by the Rebel Army. Odette tries to save Nowan, but while they succeed in breaking out they are defeated by Allen O' Neil and his son and captured. Luckily for them, Annette soon arrives and rescues both of them before escaping with them back to the Invaders' homeworld.

When Nowan and Schwarz Metzelei were paired together for a mission to Earth, Schwarz attempted to eat Nowan because they "looked" too much like prey. Odette goes to defend her comrade, causing their ship to crash-land near a Rebel Army base. The two later find an alien ship and escape back to the Invaders with it. Odette reports Schwarz's behavior to Annette and she decides to leave Schwarz on Earth as punishment.

Odette later heads to Earth to spend a summer vacation there but when arrives she discovers almost everyone has had their aggression ramped up because of a "boreal matter" that someone unleashed. Coming across Nova and Rita, Odette explains the situation to the two and goes with Nova to find the person who unleashed the "boreal matter". Along the way, they encounter a group of Ptolemaic soldiers led by Miharu and several. After Miharu is somewhat brought to her senses, she compliments Odette for her dress and states that if she had a child, they'd look a lot like her. The two eventually discover that the Professor is the one behind the "boreal matter" after encountering a Mars Robot and go to confront him. The two fight the Professor in Rugname X, but eventually learn that the "boreal matter" is only temporary and will soon wear off. Nova attempts to pursue the Professor but Odette holds her back to prevent her from being crushed by Rugname. With everything back to normal Odette resumes her vacation.
