A question was asked over on the Battle Board. Kinda hoping you all over here can give some commentary about it. The question was about where the real power lies... In Thor... or in Mjolnir.
I do not intend this to be a versus thread, so please don't treat it as such. However, this is what I think, and want to know if anyone agrees with the logic or not, and why.....
Recently, Thor was battling to save Asgard when the Skrulls attacked.
During that battle, Thor tossed Mjolnir to Bill to show everyone that Bill was not a Skrull, and Bill used Mjolnir to power himself up.
I believe that the enchantment grants an exact duplication of the powers of Thor. No division of those powers, no loss of powers on behalf of Thor when another gains the powers. Just an exact copy of the powers contained within the hammer, IF you are worthy, of course, which we all know Bill is.
So this tells me the powers are contained in the Hammer, and are specifically powers that the Hammer grants to the wielder. Which also tells me that they aren't inherrent in Thor, but in the Hammer.
Whatever Thor's personal powers are due to his being born from the union of Odin/Gaea, they are different than what the Hammer grants him when he is in possession of the Hammer. Why? Because I do not see Thor doing most of the various things that he does with the hammmer, when he is not in possession of the Hammer.
Thor does not create mystical vortices without the hammer in hand.
Thor does not channel anti-particles unless he has the hammer in hand.
Thor does not fly unless Mjolnir is in his hand.
Thor does not open dimensional portals or spacial rifts unless Mjolnir is in hand.
Thor does not create barriers or shields unless Mjolnir is in hand.
Thor doesn't absorb power sources (such as Pangoria's magnetic energy, Magneto's personal magnetic field, Skywalkers cosmic raging tempest, Pluto's deadly fire flame, Magic spells, etc....) thrown at him unless Mjolnir is in hand.
Thor never goes invisible or intangible on his own, but can when he has Mjolnir in hand.
The list goes on. So clearly the power resides in the Hammer. Not himself. Because he is never shown demonstrating these powers on his own without Mjolnir. He only demonstrates them when Mjolnir is in hand.
Some things we have seen Thor do on his own, like weather manipulation, channel Thunder and Lightning, stuff like that, because it's been clearly said those are inherrent powers, and can be done irregardless of whether Mjolnir is in hand or not.
Plus, I should remind you that Thor was once unworthy to wield Mjolnir and could NOT power up, wasn't he?. If those powers were IN Thor, then he wouldn't need Mjolnir to power up with.
So Mjolnir isn't just a conduit. Mjolnir is the source of many of the powers that Thor demonstrates.
Here are Thor's basic powers:
Thor, sans hammer, has fired energy blast before (against Durok, against Hercules, and a very old example, from his finger tips). We know he is strong and invulnerable by himself, with or without the hammer, that is a given. So...I really don't know what you are asking here.
The hammer is a tool. Thor use it to channel his attacks, but it doesn't mean he cannot whip up an energy blast on his own, he just needs the hammer to focus it. Take note the Silver Surfer, he can fly without his board, but he is more efficient with it. Kind of like the same deal here.
About Thor, at one point, not being worthy...During Dan Jurgen's run (right?)...he couldn't lift mjolnir, true, but he had plenty of power on his own (he didn't need to "charge up").
About the other exotic powers you listed, well, in cartoons he can fly without the hammer. In comics this was not specifically shown, but it doesn't mean he cannot do it. After all, creators are not really concerned regarding message board power discussions. They are more keen to tell a good and entertaining story, and Thor twirling his hammer to fly is gosh-darn as good an eye candy as Anne Hathaway in the buff.
