Dr Thomas Light is the human scientest that created megaman.
Before Mega ManEdit
In the 20th century, Thomas Light attended the Robot Institute of Technology (ローバート工科大学? Robert Institute of Technology) where he met Albert W. Wily and became classmates. The two graduated together with their doctorate degrees (PhDs), although Light always received more credit than Wily. The two were nominated for the Nobel Prize for physics, but only Dr. Light won. Dr. Wily, with his pride hurt and tired of being in second place, vanished, and Dr. Light didn't see him again until the events of the first game. At an unknown time, Dr. Light (alongside Dr. Wily in some sources outside of Japan) founded his laboratory to further the development of computing and robotics technology for the benefit of mankind in the coming era. Light became a world-renowned scientist and the leading expert on robotics.
Light built a series of household and civil service robots. Not long after that, he created a humanoid robot with a much more advanced A.I., DLN-000 Proto Man, the first "advanced robot", known as a Robot Master in some sources. However, Proto Man's dangerous imbalance in his energy core and having a strong sense of independence, went A.W.O.L. before his repairs were complete in fear that his personality would change in the process. Yet, in the year 200X (sometime in the first decade of the 21st century), Light would build on the successes and failures of the Proto Man project to build other Robot Masters, like Rock (a lab assistant, also known as Mega), Roll (a householder), and a series of industrial robots.
When Dr. Wily grew jealous of Light's works receiving credit and his works not (in USA sources he's jealous because Light received all the credit for the team's work), he stole and reprogrammed Light's industrial robots, attempting to take over the world. Rock, having a strong sense of justice, volunteered to be converted into the super robot known as Mega Man.
After converting Rock into Mega Man, Mega Man fights against Dr. Wily's forces and manages to defeat him. After Wily's first defeat, he tries to conquer the world again several times, and Dr. Light has been developing new inventions to help Mega Man counter Wily
