Supergirl (2011) #1

Meet Supergirl. She's got the unpredictable behavior of a teenager, the same powers as Superman – and none of his affection for the people of Earth. So don't piss her off!

Something that looks like a meteor shower lands on Earth, which is investigated by an unrevealed organization. When the biggest of the 'meteors' land in Russia, the organization sends two intercept teams to the crash site.

Kara Zor-El awakes in a blizzard in Siberia, but doesn't feel very cold. She initially believes herself to be dreaming, reinforced by her wearing her post-graduation uniform she has yet to earn, and various other factors. She is confronted by the intercept team (men in powered armors) who attempt to inform her she is in a restricted area, which she does not understand due to the language barrier. When they try to 'contain' her, the sun rises. Her powers activate, though using them against the intercept team has varying degrees of success. When she breaks apart the armor of one of the attackers, she tries to interrogate him of her current whereabouts, with little success. Superman appears on the scene, knocking out the remaining attacker. He tells Kara to stop.
