The Stallion's memory of his family is minimal and vague at best. He had never known his father, since his mother was forced upon by a mutant beast. Boi-Tatá served as a constant reminder to his mother of the violent encounter. He had seen the scars that she carried and, though she never spoke of them, he knew how she had acquired them. She could never learn to love Bo, though there were times where he felt that she tried to and even came close, but he could always see the look of fear and sadness in her eyes.
Bo was only a few months old when his mother disappeared. He had awoken one morning to find that the cave the two shared was completely empty. The stallion never knew what had happened to his mother, he could only guess. Though he had many theories, Bo decided that it was most likely that he had simply been abandoned. His mother could no longer live with the regret and the fear that he represented.
Most foals would have perished on their own, especially in the swamplands. Bo, however, managed well on his own. He found plenty to eat and quickly learned which creatures to stay away from. He continued to sleep and make a home of the cave that he and his mother had once shared. Secretly, he had even hoped that perhaps one day she might return.
Years later, Bo has had very little contact with the outside world. He has learned to keep to himself and is not used to company. Whenever other soquili enter his swamp, he tries to lure them further in with his bright, spider-like, eyes. Often, he lures them into traps or deeper into the swamp leaving them completely lost. In a sense, he has become the very monster that his mother always thought him to be.
