The Power of Grayskull is no more as DC Comics has killed off He-Man!

Last week saw DC Comics publish the third part of their He-Man/Thundercats crossover which sees Mumm-Ra stabbing Prince Adam right through the chest with the Power Sword. However, Adam was able to say, "By The Power Of Grayskull," just in time and stave off death's door by transforming into the mighty He-Man.

Later it's learned the evil Skeletor is actually behind bringing Mumm-Ra to Eternia as Skeletor consumes the ashes of Mumm-Ra (Mumm-Ra's dead?!) to empower himself enough to use the Power Sword himself! When Skeletor utters those famous words, "By The Power Of Greyskull... I have the power!" He-Man transforms back into Adam and dies!

Now Skeletor has both the Power Sword and the Sword of Omens!
