After seeing that clip in avengers 2 trailer, every body is wondering that is it really impossible to pick tho's hammer? well not at all, not really:
superheroes who have lifted Thor's hammer:
No limits to supes power, but he was able to lift it when Odin lifted the enchantment. And when dc/marvel cross overs happened. Good times eh?
2:Beta ray bill:
Most worthy of mjolnir, that even the hammer gets confused whether its thor or not! he finally got a new hammer built for him by odin!!
which makes me think will cape be able to lift it after Thor is battled down as seen in avengers 2 trailer? we will see.
again, during a dc/marvel cross over.
odin, borr, burri..may be even baldur!
Just some guy with Thor trapped in his head....nothing to worry about...he is dead.
Mjolnir can be picked by non-living that is to say androids..
8:Storm from x-men:
Long story short. it was a copy by loki!
Thorwas once turned into a frog but mjolnir could still recognize him!
yeah , ofcourse ...but he was being mentally controlled!!
Yeah , its metallic .
