I don't think it's the arrancar who can single handedly take down soul society. I think it's more to do with the best menos grande (I forgot their name even thought it was like 2 anime chapters back, lol). If Aizen gets a hold of 10 of those, then they would take down soul society. I think the arrancar are more like vice captains to aizen, tousen and gin. Unless Aizen actually has one of them uber menos on his side.Originally Posted by LobsterMagnet
