Son

Ostbaum Zavar (オストボーム ザバー osutoboomu zabaa) is an Arrancar and a member of Apargon's elite, Cazar. Found by Apargon alongside his sister stranded in the dunes of Hueco Mundo, the both of them have been at Apargon's side the longest compared to the rest of the elite group. Nearing the creation of Apargon's Arrancar Army, Ostbaum and his sister were to be the first Arrancars to have been modified by Apargon's experiments. However, Ostbaum was the only one affected, causing a sense of responsibility to fall upon him to protect his sister, who didn't gain such power.

Now known as Son (息子 Musuko), Ostbaum's power and natural skill for leadership has earned him a place as an elite and a bodyguard for Apargon during the Hueco Mundo Conflict. Having led the the less key battles fought during the war, backed up by the plans and strategists brought to him by his sister, Ostbaum has become a notable fighter in the war. He has effortlessly fought against other strong Arrancars without the need for his Resurrección, perfecting his swordsmanship and combat skill in order to make sure that his sister may never need to join the front-lines in harms way.
