You keep rambling on to other topics and it makes it hard to continue a discussion, lest we just ignore your posts. Ulquiorra was shown to become an arrancar without Aizens help. That is canon, drawn by Kubo himself.

As for the OP, well, clearly he was a natural Arrancar because he was already one when Aizen first met him, ergo Aizen cant have created him and the fact that we saw Ulquiorra and even at the very begining of Bleach, the substitute shinigami arc, grandfisher was created as one by other arrancar, not Aizen and the hogyoku. So we know it is very possible

Quick question, if the 2 strongest, Starrk and Ulquiorra, were natural and Nel, Nnoitra, Szayelaporro, and Aaroniero were all natural then why was the hogyoku so important? I get that the rest were able to be mass produced because of it and that's how Hallibel and Grimmjow became arrancar but it seems that some of the scariest were naturally evolved and about half the current generation of espada, plus Nel who seemed stronger than Nnoitra the fifth rank espada, were natural so I just don't get why the hogyoku was seen as a big factor in the war outside of Wonderweiss and Aizen's evolution
