Robo-Robotnik V2.0's early history was largely the same as his Mobius Prime counterpart's, including his jealousy at Colin for receiving more attention from their parents, accomplishments during the Great War, his coup d'état to take over the Kingdom of Acorn, meeting with Ixis Naugus and his war against the people of Mobius. There are some minor differences however, such as Robo-Robotnik roboticizing his universe's version of Colin Kintobor "earlier on", though it is unsure when or where that happened.
