Actually thats all incorrect. Metastacia's power was to fuse with a persons body and take control of it as its own. If it was killed it would disintegrate and return to hueco mundo. After that instance the last time when it fused with kaien it returned to hueco mundo and was absorbed by Aaroniero thus he gained metastacia's powers and in turn kaiens abilities. Metastacia's ability to return to hueco mundo and reconstruct itself was a failsafe for eventual study preset by Aizen. Metastacia is a creation/test subject after all. Most importantly Aaroniero had a multitude of powers and abilities form all the hollow it absorbed, which all amounted to much of nothing in the long run. Also how would he respawn in hueco mundo if he was already hueco mundo and in turn why would one specific failsafe of one absorbed creature out of the 33,650 that it absorbed matter. If it did wouldnt it have worked when Metastacia came against Aaroniero in the first place. Lastly the only confirmed espada to survive (by kubo himself) Harribel and Grimmjow. Aaroniero is dead and this was confirmed by the Espada themselves in chapter 269.
