Master Overlord is a transformation of Neo Metal Sonic used in an attempt to finally realize the Eggman Empire for his creator.
History
From Metal To Master
As part of his scheme to expand the Eggman Empire in his master's absence, Metal Sonic hatched a plan to use the power of the Master Emerald and the bio-data of Sonic the Hedgehog and Shadow the Hedgehog to transform in the Master Overlord. Having already copied Sonic's bio-data from an encounter on the Egg Fleet, Neo Metal Sonic took the next step by having the Egg Fleet successfully invade Angel Island in Knuckles the Echidna's absence. After that, he simply lay in wait atop the Master Emerald until Sonic and Knuckles arrived, transforming into Super Neo Metal Sonic. He had both of them on the ropes, until Shadow eventually appeared and used his manipulation over Chaos energy to revert Neo Metal Sonic back out of his super form. Neo then copied Shadow's bio-data and using the Master Emerald's power finally transformed into the Master Overlord. (StH: #7, #8, #9, #10)
