Dr . Lugae ( Dimensions ) Dr . Lugae is a non - playable character in " Final Fantasy Dimensions " . He is a scientist working for the Avalonian Empire , and the creator of the Argy weapons . Story . Dr . Lugae ' s origins are mostly unknown in the game : He ' s known as a gifted scientist who the Emperor relies upon for the creation of arms and artillery for the sake of the Avalonian Empire . After briefly appearing in the prologue , his first true appearance is at the end of Chapter 2 , where he speaks to his robotic creation , Argy . He intends to teach her about the science and mystery of the world ( specifically , naming and memorizing the stars in the sky ) , before Cid arrives , claiming that Lugae is becoming far too attached to his work , and that Argy was designed to be used as a weapon , rather than as an avatar through which the doctor can live through after death . Cid , requiring Argy for use on the Heliogabalus , takes her away from Lugae , asserting that the doll is now under his command . En route to Fabrica , where preparations will be made to integrate Argy into the Heliogabalus , Lugae pleads with Cid to give him a little more time with Argy , since he believes that she ' s unready to be used as a weapon . He defends his robot when Cid kicks her , and ends up getting knocked to the floor because of it , causing Argy to rage out of control and accidentally be blown off the ship . Once at the Heliogabalus , Cid speaks to Lugae , telling him that the Warriors of Light have found Argy , and are bringing her to Fabrica Cave . The doctor travels with him to the Engine Room of the warship to meet with his ' daughter ' , but is shocked to find that Argy has absolutely no memory of her former master . Cid uses his own technology to take control of Argy , then uses her to attack the team . Argy manages to overcome Cid ' s influence when Sol and Sarah reach out to her , and Cid infers that Lugae must have made modifications of his own to the droid in the way of artificial intelligence . To Lugae ' s horror , Cid reveals that he has made a new prototype based on the doctor ' s research , labelled ' Argy - 2 ' . He uses this creation to take out the original and her friends , but it is defeated in battle . Following this , Argy herself burns out , and in her final moments of consciousness comes to recognize her father . The Heliogabalus begins to explode ( likely due to Cid ' s intervention ) , and Lugae , after seeing the compassion with which they treated his child , decides to help them escape . Dr . Lugae finds a ship for the Warriors of Light to use at a dock in Fabrica Cave , and they leave the continent aboard it . Along the way to Berth , he tells the team why it is that he betrayed the Empire : After spending so many years pouring his heart and soul into Argy , he couldn ' t bare to hand her over to Avalon , who would have used her to kill thousands of people and enslave the world . When the boat reaches the port of Barth , Dr . Lugae suggests that the group moves on , as the Empire has probably sent out a platoon of soldiers to eliminate the ship and the doctor . He is , however , still present at the docks when Sol , Aigis and Dusk find that Sarah has gone missing , and he agrees to take him to the northern part of the continent , where the castle of Burtgang lies . Along the way , the ship is discovered by enemy forces , and Lugae urges the three to jump off the ship to escape danger , while he and Argy ( whom he rescued from the Heliogabalus ) deal with the Empire . Lugae later rescues the party from Castle Burtgang by using the dilapidated boat , which he has since transformed into a working airship . He ' s with the party in Chapter 4 when the group is taken to Mysidia , and communicates with them via Whisperweed when they infiltrate the Heliogabalus to stop its bombardment of the floating city . After the Worlds of Light and Darkness merge to form the World of Dusk , Lugae travels the world with the Warriors of Light and Argy at Sophia ' s instruction to find remnants of life in the cities and towns , and to find out what happened to the planet after the dimensional shift . Later on in the story when the unified eight warriors enter the World of Nil , Lugae and Argy communicate with them using the Whisperweed again . After the party defeats Elgo in the depths of the void , the doctor joins forces with Sophia and Barbara to combat the forces of Nil and restore peace to the land . In the ending sequence , after peace has been restored , Dr . Lugae and Argy take Diana and Sol to Burtgang , where Sarah is to be enthroned as Queen of Burtgang . He is present with Argy at the castle when Sarah is finally crowned as queen .
