Description
Oliver Atton, who is known as Tsubasa Ozora in the original Japanese version, is the central character of Captain Tsubasa, and this description covers the young version of him: the elementary school boy who appears at the beginning of the story. At this stage he is about eleven or twelve years old and has recently moved to the city of Nankatsu with his mother.

His deep attachment to football began in early childhood. When he was barely a year old and still learning to walk, he was nearly struck by a truck while playing with a ball, and the football he held in front of him cushioned the impact and saved his life. From that day onward, the ball became almost an extension of himself, and he never parted from it, practicing constantly wherever he went. His father works as a sea captain and is often away at sea, so he is raised mainly by his mother. Shortly after arriving in Nankatsu, he discovers a local football pitch where the elementary teams of Nankatsu and Shutetsu are competing for the right to use the field. He is immediately impressed by the outstanding goalkeeper Genzo Wakabayashi and challenges him to a one-on-one duel, an encounter watched by Roberto Hongo, a former member of the Brazilian national team and a friend of his father, who later becomes his mentor.

Personality-wise, young Oliver is cheerful, playful, and sharp-minded. He loves football above all else and speaks about it with a passion that inspires those around him. Although he is at first somewhat lonely as a newcomer, he is not bitter or withdrawn; instead he is open, friendly, and quick to use football as the main way of connecting with others. He is also remarkably disciplined for his age, practicing diligently rather than relying purely on natural talent.

His motivation is clear and constant: he dreams of becoming the best football player in the world and of one day winning the FIFA World Cup with Japan. Every match, training session, and challenge he faces during his childhood serves that dream.

In the story, he joins the Nankatsu elementary school team and quickly becomes its driving force. Through the local tournaments he meets teammates and rivals who shape his growth. With Taro Misaki he forms a nearly telepathic partnership known as the Golden Duo, a combination of passes and movement that becomes famous throughout the competition. His first major rival is Genzo Wakabayashi, whose extraordinary goalkeeping pushes him to improve; their rivalry gradually warms into friendship and mutual respect. He also clashes with Kojiro Hyuga, a powerful and aggressive striker whose team repeatedly threatens Nankatsu, and with other standout players such as Ken Wakashimazu, Jun Misugi, and Hikaru Matsuyama. Sanae Nakazawa, a girl from Nankatsu, becomes his most devoted supporter from these early years. His relationship with Roberto Hongo is especially important, since Roberto recognizes his potential, guides his development, and serves as a father figure during a childhood in which his own father is frequently absent.

Over the course of the elementary school arc, Oliver develops from a gifted loner into a true team player. He learns to trust his teammates, takes on responsibility in difficult matches, and carries the Nankatsu side through injuries and setbacks, eventually helping them win the national championship. These early experiences build the foundation for his later career, and his abilities continue to expand as he matures.

As a young player, his talents are extraordinary. He has superb ball control, quick and agile dribbling, accurate passing, and shooting power that is unusual for a child his age. He is described as a prodigy who can observe and reproduce techniques after seeing them only once, which allows him to absorb new skills from opponents and teammates alike. He is also skilled at acrobatic plays such as the overhead kick, and his combination play with Misaki is considered almost unstoppable. In his early years he plays primarily as a forward, though his vision and passing already hint at the playmaker role he later adopts. His signature shooting techniques, including the Drive Shoot, appear as he grows older and continue to define his playing style in later stages of the story.
