He and his cousin Jorge own the Newsboy Legion, a group of people leaded by them to save Comet City and the rest of the country from villains.
Sergio is the youngest of the two sons raised by the late couple Samuel and Mary Elizabeth. When he was 3 years old, he was diagnosed a cardiac problem that, at an age such as his, would cause his death. However, his life was saved when Alfonso, a fellow scientist from Samuel, implanted one of his Biometals in his investigation to create bioweapons.
Sergio continued to grow and live a peaceful life with his mother and his cousin Jorge. Eventually, Mary Elizabeth passed away and the two cousins began to live on their own with their pet dog Bady, working as mechanics to get some income.
A turn of events made him meet the daughter of Comet City's mayor, Marta, who sensed some potential within him. The legends of the land tell the story of a hero that protected it against any sorts of evil, and that hero was somehow Sergio himself. Just then, Alfonso, plotting his revenge for being expelled from the Science Community years ago, kidnaps Marta with the idea that her father would surrender the city in exchange for her safety. However, thanks to the Biometal that was implanted on him as a child that granted super speed, as well as an arm cannon that Marta gifted him, Sergio was able to thwart Alfonso's plan and rescue Marta, earning him oficially the status of hero.
During his adventures, Sergio has met a lot of friends and foes, and continues doing so up to this day.
Sergio is a young white male with brown eyes and spiky brown hair. His age is uncertain, but he appears to be on his early 20s. His everyday clothing consists of:
- A blue hat
- A black T-shirt underneath an unbuttoned blue shirt
- Blue fingerless gloves with black cuffs
- Brown pants
- Blue-colored Sonic shoes
Powers and abilities Edit
The Biometal that was implanted on him as a child granted him the power of super speed but he wasn't quite able to control it until he found out he had become the hero of the city.
His weapons of choice are and arm cannon that was given to Marta after meeting him for the first time and telling him the legends of the land and a blue-colored wrench that he uses for close combat.
He is also able to use many power-ups that he finds on his adventures and achieve a Super Form with the Kingdom Crystals.
Sergio is a kind-hearted and easy-going person, but sometimes a bit of a snarker and with the habit of making bad jokes. While he never thought he'd be a hero, he seems to have accepted his role very well, willing to help his friends if needed.
Deeply, Sergio is afraid of being alone. This makes him very worried for his friends and feels responsible for their safety.
