Supergirl: A True Kryptonian

What if Kara didn't turn out like people wanted?

What if Supergirl killed?

What if Kara was not like she's always been?

Kara falls to earth after the death of her planet, lives with the Danvers, becomes Supergirl, and was like we knew her.

But what if she was a little different?

Kara is fed up with crime, with heros not doing what needs to be done, and her wimp of a cousin. she takes matters into her own hands and starts to fix the world.

she'll do what's needed, what's nesscary for the world to prosper. she'll do what it takes to not let earth make the same mistakes as Krypton.
