Impossible Odds

I punched through the window and grabbed the weapon, ignoring the pain shooting up my arm and the blood dripping down it.

The thing made a sound like a truck backing up, but I knew it was basically laughing at me. I felt the voice in my head, first as high-pitched wailing and then as English.

"That's the thing about us Humans, we don't give up, even facing impossible odds!"

"Wait, Humans? Great, another ruined universe!"

It vanished, which was good, obviously, but I still feel a little disgruntled, yeah?
