William Afton threw himself into his next project with a fervor that bordered on obsession. The pizzeria's existing animatronics, once merely tools of entertainment, were to be transformed into instruments of his dark ambitions. He envisioned an army, each unit a deadly extension of his will, capable of carrying out his plans with ruthless efficiency.

He started with the existing animatronics—Freddy, Bonnie, Chica, and Foxy. Their designs were already intimidating, but they could be so much more. Afton upgraded their endoskeletons, reinforcing them with stronger materials and integrating advanced servomotors for quicker, more precise movements. He enhanced their sensory systems, equipping them with night vision, thermal imaging, and advanced auditory sensors. Their outer shells were modified to appear more menacing, with sharper teeth, glowing eyes, and an almost predatory stance.

But he didn't stop there. William Afton began to build new animatronics from scratch, each designed with specific roles in mind. Some were constructed for brute strength, capable of tearing through obstacles and overpowering any adversaries. Others were designed for stealth, able to move silently through the shadows, gathering information or ambushing unsuspecting targets. Each new creation was a masterpiece of engineering and malevolence, an embodiment of his twisted genius.

As he worked, he felt the presence of the absorbed souls within him, their energies fueling his creativity and drive. He channeled their anguish and rage into his creations, making each animatronic not just a machine, but a vessel of vengeance.

He knew that building this army consumed more energy than simply acting alone, but it was a calculated investment. Having an army of loyal, deadly animatronics would provide him with the means to conquer not just the pizzeria, but the world itself. It was a shortcut, a way to amplify his power and extend his reach far beyond what he could achieve alone. And he relished the thought of unleashing this mechanical horde upon an unsuspecting world.

Hours turned into days as he continued his work, meticulously programming each animatronic with advanced AI, ensuring they were capable of independent thought and action while still remaining utterly loyal to him. He installed fail-safes and override protocols, guaranteeing that no one could turn his creations against him.

Finally, his army was ready. The pizzeria was now home to a legion of animatronics, each more terrifying and deadly than the last. They stood in the shadows, their eyes glowing with an eerie light, awaiting his command.

William Afton surveyed his work with a sense of grim satisfaction. He knew that when the time came to enact his grand plan, he would be ready. His army of animatronics would be the vanguard of his conquest, spreading fear and chaos wherever they went.

"Prepare yourselves," he murmured, addressing his creations. "The world will soon know the name William Afton."

With everything in place, he allowed himself a rare moment of rest. He powered down briefly, letting his mind settle and his energies replenish. When he powered back on, he felt a renewed sense of purpose and determination.

The world outside was blissfully unaware of the storm that was about to be unleashed. But soon, very soon, they would learn to fear the name William Afton and the mechanical nightmares he had brought to life.

His reign of terror was far from over. In fact, it was only just beginning. And with his animatronic army at his command, he was unstoppable.
