- Alpha is another creation of Laboratory 1718 after Saber left. Mad scientists got a new idea from a famous sci-fi movie. Using human bodies as biological material and space meteorolite as metal skeletons, they created powerful twins. Alpha and Beta, also known as \'Flesh Weapon\', are capable of utilizing a supernatural power that\'s ubiquitous but very mystery. However, the twins had always had a strong conscience, and refused to become killing machines. Getting help from Saber, they escaped from the alt-world. However, on their way to escape, Beta\'s core was destroyed. All that Alpha could retrieve, was Beta\'s half metallic arm. After coming to the Land of Dawn, with the help of master machinist Rooney, now Beta keeps company with Alpha as a form of an aircraft.
