4. Sif Attacks The Destroyer (Thor)
Marvel StudiosIn the first Thor movie, after Thor had been exiled to Earth for his invasion of Jotunheim and the Warriors Three and Sif had arrived to retrieve him from his exile, Loki sent the powerful Destroyer Armour to stop the quartet from doing so. After it had quite easily repelled the attacks of the Warriors Three, Sif took to the rooftops of the small New Mexico town they were all in and attacked the Destroyer from above. Acrobatically jumping down on to it with an inimitable and somewhat sexy style, she rammed her spear in to its back so hard that it came out through its chest. Granted, the move didn't actually defeat the Destroyer - it was shut down for a moment before springing back to life - but the move itself, the guile and the warrior spirit shown by Sif in attempting to take it down by herself was awesome.
