Doctor Thomas Light, known in Japan as Dr. Right (Dr.ライト, Dokuta Raito?), is depicted as an aged scientist, who is a peerless roboticist and winner of the Nobel Prize. He is the creator of protagonist Mega Man and several other robots. While a pacifist, he reluctantly recognizes that the use of force can be a necessity. He plays a supporting role, often developing and distributing new gear. In the Mega Man X series, Dr. Light resumes his supporting role through enhancement capsules that contain upgrades to X's systems together with messages relayed by silver/blue, slightly translucent holographic projections.
