Robert is the only son of Alberto Garcia, a wealthy Italian businessman and best friend of Takuma Sakazaki. During his early childhood, Robert lived a life free of responsibility and caring, being doted on by his loving parents for his every whim. Yet he would yearn for more in his life and would regularly sneak away from his home to go to the Kyokugenryu Dojo. He spied on Takuma and Ryo Sakazaki's training sessions and aspired to become like them.
Alberto wanted Robert to focus on his corporate teachings and someday inherit the Garcia Foundation from him. After his father pushed him too far, a young Robert rebelled and embraced his own ambitions to find success by himself. Running away from home, Robert rushed to Takuma's dojo and demanded to be taught Kyokugenryu Karate. Impressed by the boy's spirit, Takuma agreed and Robert became Ryo's sparring partner. The two boys soon became best friends.
Unlike Ryo, Robert is a natural ace in martial arts. Because Robert excelled so well in his studies, Takuma became harder on his son's training to keep up. Robert completed his training first and returned to Italy shortly before Ronnet's deadly car accident. In his home country, Robert continued his martial arts studies and matured into a respected martial artist. He was given his moniker overseas.
Robert eventually developed romantic feelings for his friend's sister, Yuri. He has held an infatuation with Yuri ever since he first met her and would likely wed her if not for Takuma and Ryo, who are overprotective of Yuri.
