Over the years, the madman realized his monsters became more alert, more… intelligent. Intrigued by this unexpected turn of events, he managed to isolate some of his most vivid subjects into special cages. And to his surprise, after multiple stimulations through electrical shocks and drug consumption, some of them became more attentive to the world around them. They were slowly growing… self-aware. His mind was blown off, astonished by the fast progress his creations had accomplished. Thrived by this wondrous development, he selected his most cognizant creatures and proceeded to various dissections and examinations, always learning more about their cognitive abilities. If his first monsters had been completely sustainable and viable, his new generation would be just as bright and receptive as a human was. Each time one of his beasts had awaken from the unconscious slumber of its wildness, he simply released them into the wild, watching how they would adapt to their new existence. Obviously, his very first newly aware subjects were nearly all mentally unstable and the vast majority of them simply couldn't handle their new condition. And so many of them blatantly committed suicide.
With time and practice, Gaster succeeded to create monsters not only gifted with consciousness, but also demonstrating a will to live and create. He assisted to the birth of a micro-society able to thrive and develop itself without his guiding hand. They had even created their own idiom! His twisted mind felt accomplished each time he took a glance at this little world born from his lunacy, even though their little way of life was mostly a pitiful attempt to survive as large groups. Their "cities" were little lamentable shacks and sheds gathered in various biomes and they didn't occupy much space. And hence they were afar from his laboratory, they lived their sad lives without even coming across him. They weren't even aware of his existence. Although, he didn't wish to be revealed to the monsters, and so he sheltered himself into the shadows of his home, hiding from his own work, watching, taking notes.
However, as time passed, he became older and conducting his experiments became a laborious task to pursue on his own. Then, an interesting flourished in his mind. He needed an assistant. It now appeared clear to him: if he aspired to continue as he had for the past years, he shouldn't do it companionless.
From that day forward, he worked on creating a little beast that would obey blindly and submit to him, and that would, at the same time, be as skilled and competent as he was. He used various specimen, but one in particular presented more potential than the others: it consisted into a little yellow lizard, which he had grown to the size of a seven-year-old child through genetic manipulation. After months of hard work and maniacal caring, the little female lizard had developed a brilliant mind and she listened to him as if he had been the wisest man in the world. Well, it might have been her reality, since her whole world ended where the doors of the laboratory stood. Her yellow skin turned a bit to the grey due to what he had done to her, but ignoring that fact, she was perfectly healthy and ready for duty.
Then, he equipped her with improvised clothing, goggles and gloves, but, most importantly, a name: Alphys.
