This topic is prety old but just 2 let u know, bleach is way past the gay bounts... after the bounts basically it introduced the vizard and the arrancar, the arrancar are under Aizen's control which is why he need the Hougyoku from Rukia's body. the strongest arrancar are called the espada(there are 10 espada, 1 is strongest, 10 is weakest). heres a vid of vizard Ichigo(vizard are ex-shinigami who gained hollow powers/masks) fighting the 6th epspada grimmjow.
