From Wikipedia, the free encyclopedia
 
“Secret Invasion” is a comic book crossover storyline that ran through a self-titled eight issue limited series and several tie-in books published by Marvel Comics from April through December 2008.  
The story involves a subversive, long-term invasion of Earth by the alien Skrulls. Capable of shapeshifting, the Skrulls have secretly replaced many of Marvel’s heroes with impostors over a period of years, prior to the overt invasion. Marvel’s promotional tagline for the event was “Who do you trust?”

“He loves you.”

When in doubt, assume everyone is a Skrull Cylon changeling. Including you.

Let me see, whom do I know that’s undergone a complete personality change overnight?

You know, it’s not really a secret if your magic is a completely different color than normal. I mean, I could understand someone not noticing if the changed a guard or something, but the ruler of everything? I’ll give it 5 days. Tops.

Like if it wasn’t easy to identify a changeling.
 
“Hey Princess, I totally don’t notice that your eyes are green for no apparent reason out of nowhere, how’s it going?”
 
Right?
