At first, Jacob was human, he lived with the Xcutions and was a powerful fullbringer with his fullbring; Black reaper. He made a deal with Sosuke Aizen to train in Heuco mundo for a week with a fellow Xcution; Toby Armstrong, to train to become stronger and evolve their fullbrings. When the two of them arrived, they were greated by Aizen, Gin Ichimaru and Ulquiorra Cifer who gave them a warm welcome and asked to see their currennt fullbrings: Toby went first; his fullbring is a clad-type fullbring and is a strong armor which he stated that it was bigger and stronger than it usualy is which Aizen then said that it is no surprise his fullbring is stronger as the atmosphere in Heuco mundo has a very high concentration of reishi, higher than in the world of the living and in the soul society. Jacob then showed his fullbring; it was another clad-type, it was a black arm glove on his right arm, a black katana, a black outfit and a helmet which everyone believes looks like a hollow mask. Ulquiorra escorted them to a large room with grey walls and grey sand as the floor, Jacob recognised that the sand was designed to absorb and keep in any reishi and spiritual pressure that it comes in contact to. Ulquiorra stood by the door while Jacob and Toby had a fight to train in their new fullbrings.
