Alexis was born as the son to Lambros. As he grew up, Alexis shared a mutual bond of love and respect with his farther. While Alexis was proud to be the son of a sailor like Lambros, he often felt lonely because Lambros' job as a sailor meant he would go on long trips, meaning he rarely saw his father. Despite this, Alexis held no ill will against his father for that.
As a result of the earth breaking apart in the beginning of Sonic Unleashed. Alexis' father was left stranded in Apotos. Alexis however, was left rather thrilled by this as it meant he and his father could spend some more time together.
In the beginning of this crisis, Alexis met Sonic the Hedgehog and Chip, who asked him if knew Chip from somewhere, as Chip had amnesia. While Alexis did not recognize Chip, he could sympathize for Chip's condition. During the following night he noticed that the Ice Cream Vendor was acting weird. Not long after, Alexis had a new encounter with Sonic and Chip, and told them what he had observed about the Ice Cream Vendor, before noticing to his surprise that Sonic had changed.
While Alexis and his father were together in Apotos, they spent many joyful activities together, such as going out fishing, which left Alexis so jazzed that he could not sleep. He would often tell about the activities he had with his father to Sonic and Chip whenever they passed through Apotos, but Alexis would never admit to Sonic that he was happy that his father was stuck with him.
Eventually, Sonic restored Spagonia's continent and Alexis' father could return to work. Following this, Alexis encountered Sonic and Chip again. During this meeting, Alexis told Sonic and Chip that he hoped his father would be okay and that he was not lonely as he is "the proud son of a sailor."
During the events of Sonic Unleashed, Alexis was approached by Sonic the Hedgehog and Chip. After greeting them, Alexis asks them if they felt the tremors from the planet's shattering and explained that the whole town was turned upside down because of it. Sonic and Chip then asked Alexis if he knew Chip since Chip had amnesia, but Alexis did not know Chip. Though he could not help them directly, however, Alexis suggested that they should go see Gregorios, saying that he knew everything, though Alexis comments that Gregorios had seemed preoccupied lately.
During the following night, Alexis notice that the Ice Cream Vendor was acting weird. Not long after, Alexis had another encounter with Sonic and Chip, and told them what he had observed about the Ice Cream Vendor, before noticing to his great surprised that Sonic had transformed into Sonic the Werehog.
Over time, Alexis began to notice that other people were starting to act weird too. When Sonic and Chip later returned to Apotos, Alexis told them about how he not believe how people were acting crazy at nighttime while wondering about what was going on.
Alexis is a wild and unruly boy who loves to spend time with his father since they do not see each other often. As such, he often feels lonely. He is not one to bear grudges though: despite his father's long absences, Alexis never holds any ill will against him and remains proud to be the son of a sailor.
