@Tohno and DSpirit are you guys really a fan of the JJBA series? The World dominates only the earth(thats why the stand is called the world) while Made in Heaven can affect the whole universe that could lead into the creation or the transfer of ones self into an alternate dimension or world. Well anyways being a fan of the series is good but knowing the limitation of the chars ability is a plus so JJBA is a great manga but not the greatest until Araki comes up with a twist that would revert Made in Heavens effect back to the original time line I hope http://mugenfreeforall.com/public/style_emoticons//smile.png.
In the case of Izin sure he has immortality but what would that do if Master Roshi(or the stronger char) imprisoned him with the Mafuba lol :GHEYFACE:
Btw I thought the bleach series ended with the defeat of Izin.
