As a proficient scientist, doctor and engineer, Giovanni heavily modified his own body into that of a cyborg in the attempt to extend his lifespan and become immune to many of the things that plague an organic body, such as disease and the effects of old age. As a cyborg, his entire body is made up of mechanical parts and weaponry, save for his brain, which he kept out of necessity. His body is largely made up of the highly dense and heat tolerant metal element, tungsten, as well as the resourceful alloy, wapometal.
