Ralph Matheson spent much of his young life in the shadow of his father's accomplishments as an important scientist. While the father always pushed his son to do well in school, especially in technical and scientific fields, the young man never really wanted to take part in that world-- opting instead for soccer practices and spare-time video games.
All the same, having connections to a well-funded company as his father's was had its perks: Ralph was invited to the unveiling of the design for a new prototype quantum ray handheld device they were working on. The event was attended by dozens of intellectuals from across the globe, and would have been a complete success if it weren't for one crucial mix up-- an assistant brought out the real device instead of the model! The ray was given to Ralph for a photo opportunity, and at that moment, his finger slipped over the "on" switch for a brief second and he was blasted with concentrated quantum energy.
The only sign that anything was amiss was the sudden shiver coming from the boy, during which he switched the device off.
The after-effects of the mishap became apparent to Ralph the next morning after a very restless sleep, when he realized that he had somehow outgrown the size of his bed through the night! Although he was able to eventually regain his normal height after calming down, the panic that resulted cause his parents to wake and discover what happened.
Lack of funding caused the quantum ray project to be scrapped a few short months later, yet Ralph's father still had hope that he could make good on his team's research-- with this in mind, he implored Ralph to use and hone his newfound powers.
Without taking his abilities into consideration, Ralph has an average build for someone his age that undergoes a semi-regular physical regimen. However, his physical profile when at rest can vary by a wide margin of inches and pounds.
Atomac can easily assume measurements between three-and-a-half inches and twenty-five feet before straining himself-- additionally, his mass can range from virtually weightless to an Imperial tonne.
