User blog comment:RyftLord/Hollow Ichigo-Will he come back?/@comment-4025622-20110528141908

He will come back. He has to cause he's probably the only one that will give Ichigo trouble and yet, make him stronger.

Also, I don't think Cazador de la Luna(my name for him which means "Hunter of the moon") was born in the Shattered Shaft incident but the point where he was awakened fully and tried to take over. My theory and opinion on how he was born takes places 6 years before when Ichigo's mother died. Being exposed to a hollow at a young age and the despair and pain that all wholes feel before becoming a hollow that Ichigo felt on that day were enough to give birth to Cazador who lay dormant within his soul until Rukia gave Ichigo her powers and awakened his own. There are instances where Cazador made his presence known. The first one was in episode 3 when hollow!Sora hit Ichigo and caused him to slide across the air even though he shouldn't have been able to at the time. The second instance was when Ichigo was fighting Renji and his personality became Cazadors. At these points, he was being surpressed because Ichigo's chain of fate was still intact but then comes the Shattered shaft and boom, Cazador is awake and ready to unleash hell onto the world.
