The Light Robot Masters are a group of Robot Masters who were created by Dr. Light on the alternate world of Earth 20XX. They include his robotic "children" Mega Man, Proto Man, and Roll, as well as other Robot Masters with various abilities. They often work in opposition to Dr. Wily and his own Robot Masters.
Prior to Earth 20XX being rewritten by the Genesis Wave, Dr. Light created his line of Robot Masters. Sadly, his initial creation, Blues, ended up in the service of Dr. Wily, and ended up battling against Mega Man, Guts Man, Bomb Man, and Cut Man. Blues, alias Break Man, handily defeated his brothers, only to turn away from the battle when Mega Man begged him to leave his Integrated Circuit intact for Dr. Light's sake. All five were then hit-along with their world and the planet Mobius-by the Genesis wave fired off by Wily and Dr. Eggman. (FCBD 2013)
The altered reality created by the Genesis Wave found the Light Robot Masters contending with Wily and Eggman's alliance and their Robot Master Army. When Mega Man and Sonic the Hedgehog battled after being tricked by Copy Mega Man and Metal Sonic, Mega Man called in the support units-Rush, Tango, Eddie, and Beat-to aid him in the fight. Once the two heroes discovered the deception, they contended with the evil doctors aboard their warship, the Wily Egg, the others-minus Roll, who remained behind on Earth-joined Sonic's allies in battling the army. Thanks to their arrival, Proto Man was able to break away from the battle along with Knuckles the Echidna, Dr. Light, and Rush to assist Mega Man and Sonic. Subsequently, the Light Robot Masters were returned to their proper places in time and place after Super Mega Man reversed the effects of the Super Genesis Wave. (MM: #25, StH: #251)
The Light Robot Masters later joined forces to help rebuild Light Labs, with Concrete Man joining the original line in the construction effort. Later, after Mega Man disappeared and Sonic Man began attacking Mega City, the original line was deployed to try and stop him. Unfortunately, Sonic Man proved too powerful for them to defeat, and Dr. Light was forced to call in a number of former Wily Robot Masters and Quake Woman in an effort to defeat the villain. Eventually these events would be erased from history, returning the Light Robot Masters to their place at Light Labs with no memories of the battles. (SU: #76; SB: #8; StH: #273; MM: #52)
