A Little History
The origin of Colossal Boy is pretty straightforward.
First appearing in Adventure Comics #267, Colossal Boy is the creation of Jerry Siegel and Jim Mooney. As a young hero with superpowers, Colossal Boy is able to grow his body to incredible heights. After transitioning into Micro Lad, he was also able to shrink down to near undetectable size.
Gim Allon was born to Wynn and Marte Allon of Earth. At a young age, Gim enrolled in Earth’s Science Police Academy where he studied to become a member of the Science Police. While vacationing on Mars with his then girlfriend, Gigi Cusimano, a meteor came crashing down and landed just a few meters from him. The meteor sent Gim to the infirmary where he remained for an extended period.
Shortly after his release from the infirmary, he spotted a crime happening. Even though the criminal was able to escape Gim in an elevator, the escape was short-lived. While trying to catch the criminal, he learned that the meteor had altered his cellular composition and he was now able to grow his body at will. Growing to 15 feet, Gim easily caught the criminal and gave him to the authorities.
Although he wanted to remain with the Science Police, Gim’s mother convinced him to join the Legion of Superheroes. Once in the group, he quickly rose to become one of the greatest members in history.
And that is it. The origin of Colossal Boy.
