10 Utterly Ridiculous Comic Book Weaknesses
7. Letting Go Of Mjolnir For More Than A Minute (Thor)
Although this weakness is now long consigned to Marvel history, the fact is that the classic version of Thor would lose his powers if he went without touching his war hammer Mjolnir for more than sixty seconds.
Moreover, this was when Thor's alter-ego was that of Donald Blake, and Mjolnir would disguise itself as a walking stick in order to avoid arousing suspicion.
Unfortunately for Thor, one of his main methods of attack was to throw Mjolnir at his opponents - often over long distances - so this depowering happened a lot more often than you might imagine. Even more unfortunate was the fact that, if anyone else worthy was to grab Mjolnir whilst Thor wasn't holding it, they would acquire its power and Thor would lose his. Very awkward.
