He-man Vs. Thor
Eternia's champion vs. Asgard's champion....
It's magical power sword vs. magical uru hammer in a battle to shake the foundations of Greyskull...
The battle takes place right outside the walls of Greyskull on Eternia...after Loki tricks Thor into walking thru a dimenional portal to be rid of him so he can usurp the throne of Asgard...Thor arrives at Greyskull who is mistaken for an alley of Skeletor by He-man...
So, who takes this...the most powerful man in the Universe with the power of Greyskull behind him...OR the son of Odin with the power of the elements behind him?
