William Afton:
A co-founder of Fazbear Entertainment, William is a skilled robotic engineer dedicated to crafting animatronic marvels for Fredbear's Family Diner alongside his longtime friend and business partner, Henry Emily. Their friendship dates back to their college years, forged in shared dreams of creating captivating robotic characters.

During their college days, William played a protective role for Henry, intervening when his friend faced bullying from other teenagers. This early bond laid the foundation for their enduring partnership. Together, they fulfilled their shared vision by establishing Fredbear's Family Diner, a testament to their collaborative creativity and friendship.

However, as the years unfolded, William's once-strong camaraderie with Henry soured. The success of their joint endeavors fueled William's growing resentment, as he perceived Henry garnering all the acclaim for their groundbreaking work. Personal troubles exacerbated his discontent, including a painful divorce that led to a separation from his children. Despite the challenges, William held a special affection for his daughter, Elizabeth, who often accompanied him at work.
