Re: Mjolnir
With that logic Thor could just fry supes with magic, and it really wouldn't be hard. Everyone forgets just how powerful Thor really is because Thor essentailly plays with kid gloves all of the time. Yes I know Superman does as well, but I don't know it its to the same extent. Thor has beaten, and I mean trashed Thanos in a fight toe to toe and Thanos is a galactically powerful uber-villian. Alot of that has to do with the fact that Thor knows Thanos can take, and give, a punch. Also remember that Thor has three levels of power that have been pretty neatly defined.
Regular Thor - Normal power level. Rarely uses Mjolnir to whack someone although will use it often to hit other objects, most notably projectiles. Never uses the blasts that Mjolnir is capable of and doesn't use his weather control powers(Which BTW make Storm's look sad).
"I say thee nay!" Thor - Ramping it up, he's pissed and he's letting you know. Alot of times storms rise up just to show you his mood and he uses Mjolnir alot more, particularly his choke smack whcih most people do not get up from. This is the level of power he goes to when someone around him is hurt, but not necessarily mortally, also he goes to this when he's had enough of a fight. Its rarely not enough.
"Ultron, we would have words with thee." Thor- Quite simply this version has never been beaten. This level of power has felled a celestial, this level of power has dropped Thanos, this level of power has put an unholy beating on Ultron, this level of power has made Adam Warlock cry like a girl, and this level of power is rarely, rarely, rarely used. In addition to this rank of power Thor has two items of magic he can use. His belt, which doubles his strength, and his gauntlets which help him 'unlock' more of the powers of Mjolnir, it also give him more access to the 'well of the all father', meaning he has more godly powers much like Odin.
Supes runs up against the second he's in for a world of hurt because Thor is willing to use his magic at that level. Supes runs up against the third he's done. That level of power makes Thor one of the most powerful beings in the Marvel universe, not just heroes. Supes is nasty, don't get me wrong, but when you're talking high end, and you have to in this siutation, Thor has got him.
