"Whosoever holds this hammer, if he be worthy, shall possess the power of Thor." -Inscription on Thor's hammer, Mjölnir.

This October, Marvel Comics evolves once again in one of the most shocking and exciting changes ever to shake one of Marvel's "big three"--Captain America, Iron Man and Thor--Marvel Comics will be introducing an all-new THOR, GOD OF THUNDER.

No longer is the classic male hero able to hold the mighty hammer, Mjölnir, a brand new female hero will emerge who will be worthy of the name THOR. Who is she? Where did she come from and what is her connection to Asgard and the Marvel Universe?
