Those are some scans I found which should help. The first one is the second part to the one Jaeger posted. The last two are from when the Avengers battled Osborn's new Dark Avengers. It's the Thor Clone in the scan.
On a scale of not-at-all to exactly-the-same, how similar are Thor and his clone? If it's the same one, or the same model, as seen in Civil War then the above feat impressive, but not as much as it would be were the clone closer to the real Thor in terms of power.
Also, what happened next? Did Iron Fist destroy that clone or what?
