I didn't think it would be an inanimate object but adamantium getting bent by wonderbraThor's bare hands is definitely jobbing
well, i assume it must have been secondary Adamantium, as it always is when it's broken by the likes of Hulk, Sentry or Thor, but the composition of mixed Adamantium, even secondary, and Vibranium makes a very good mix. If i'm correct, Hulk had a "panic Room" made the exact same way in Avengers (only instead of Magic, there were Gravity based contingencies).
i think it's a good showing of "the power of Thor", as used by an unexperienced wielder. A well written Thor would certainly be able to do the very same thing (and very well did in the past, on occasions).
still, i'm just waiting for New Thor Vs Mangog to happen XD
