How does yammy die?

Answer 1

I'll guess that Yammy tried to smash Orihime while Ichigo was fighting Ulquiorra and was going to interfere, but Uryu sets a land mine that Mayuri designed. He falls downs several floors, where Rukia is. After the fall Uyru was easily able to overpower Yammy and defeats him, then leaves to take Orihime to Ichigo (skipping all that). Then while Rukia, Chad, and Renji were fighting the one arrancar assassin leader, he freezes, and Yammy destroys him, which he grew greatly. Then releases his zanpakato, burning the 1, and revealing the fact after he releases, the numbers go from 1-10, to 0-9, making him the most powerful of the espada. The 3 are overpowered by Yammy. After this, Ichigo (who finished his battle, Ulquiorra killed by him, then Orihime's cry brought him back as a complete hollow and easily overpowered him. This was NOT his hollow self exactly, because he wanted to protect Orihime still) Uyru was with him. But even so, Ichigo using his hollow mask and Uryu were overpowered by yammy (Ichigo's mask vanished after 5 minutes, which still wasn't enough) Then Byakuya and Kenpachi came, and were even matched. Then finally, Mayuri came in, and Byakuya had to hold yammy down, and Mayuri had to use bankai, Ichigo used Getsuga Tenshou, Chad and Uyru and Rukia and Renji used full force as well and completely disabled Yammy. Yammy was defeated, it shows that Nel revert back to her adult self and released her zanpakuto, and she had fought him. They were near evenly matched, until she ran behind him and stabbed him in the shoulder, then the head.
