Cammy Travis, also known by the full name Camellia Travis and later Camellia Green, is a significant supporting character in Inazuma Eleven. She first appears watching the Raimon team practice, where she is immediately recognized by Mark Evans, who calls her by the childhood nickname "Cammy Cammy". At this point, she claims not to remember him and leaves. It is soon revealed that she is the daughter of the new national team coach, Percy Travis, and she takes on the role of the new team manager, replacing Nelly Raimon.

Physically, Cammy has long purple hair styled with a fringe swept to the left and clear blue eyes. Her typical attire consists of a collared white shirt, a blue tie, a teal or blue vest, and a blue skirt, paired with long white socks and brown moccasins.

In personality, Cammy is characterized by her kindness and gentle, soft-spoken nature. She is described as being cute, honest, and determined, but not prone to anger. A defining aspect of her character is her nurturing and maternal attitude toward the players of Inazuma Japan. She takes her managerial duties very seriously and acts like a mother figure to the team. This is shown through her thoughtful actions, such as preparing personalized meals, reading books to find ways to make food taste better, and putting labels on the players' bottles and towels to keep their belongings organized. Her care for the team is a powerful motivator; during a difficult match against The Empire when Inazuma Japan was losing, her heartfelt encouragement helped the players recover their spirits and continue fighting.

Cammy's role in the story is closely tied to Mark Evans, the team's captain and goalkeeper. Mark remembers her as a childhood friend from his first year of school, a time she cannot recall. Their relationship deepens as she works as manager. In one notable episode, after a misunderstanding leads others to believe they are on a date, Cammy and Mark spend time together, and he shows her his grandfather Daisuke Evans secret notebook. Cammy discovers that she is able to read and understand the notes, giving Mark valuable hints. This ability to read the notebook is a key plot point, stemming from her hidden past; the notes had been read aloud to her by her real father when she was very young.

The most significant development for Cammy involves the recovery of her lost memories. Her backstory is a tragic one. Her real parents were friends of David Evans, Marks grandfather. They died in a fatal accident while helping David Evans escape from the antagonist Ray Dark. After this traumatic event, Coach Percy Travis took her in, adopted her, and used hypnosis to make her forget the painful memories of her parents death and her early childhood. This explained her inability to remember Mark. During her time with Inazuma Japan, these suppressed memories begin to resurface, leading to moments where she falls ill. In a pivotal moment, she finally remembers everything, learning that her real surname is Green. Despite the pain, she asks her adoptive father not to hypnotize her again, as she prefers to remember her true parents and her past.

Regarding abilities, Cammy does not possess any special soccer techniques, as she is a manager and not a player. Her most notable abilities are her organizational and caregiving skills, which she demonstrates in her managerial duties. Her ability to read David Evans notebook, which was indecipherable to others, is her most unique and plot-relevant talent. Her role as a romantic interest for Mark is also a notable aspect of her character, as she is one of the two possible marriage options for him in the Inazuma Eleven GO video games, specifically in the Dark or Shadow version.
