10. Loki Escapes SHIELD's Base
This isn't impressive in itself, given\ that Loki is essentially like the boot to the proverbial ants that he is facing, but it's the style he does it in and the attitude he does it with.\ Upon his arrival on Earth via the Tesseract-created portal, Loki is told to put down his spear. But, before even getting his bearings, he blasts a SHIELD agent with it, then takes out a couple more with the pointy end of it, then throws a pair of daggers with extreme accuracy in to the throats of a couple more at the same time - all while taking bullets to his body and head as though they were flies buzzing around him. He then declares that he is burning with glorious purpose, signals his intent to take over the world, gets a couple of key members of SHIELD's staff under his control and casually leaves while the area he was just in is buried under thousands of tonnes of rock. The scene basically solidifies Loki as someone whom no ordinary human could possibly be a threat to and it's done with unrivalled style by the God of Mischief.
