Call to adventure

I'ts just a normal day for the super hero iron man being himself. He goes do the nearest subway and orders a subway melt. He then walks to the rec. center to play basketball. Then he's driving home in his nice car when he finds that pepper his girlfriend is missing. I sets out to find the man who took her.

Will he find her?

What will he do to the guy? 

What will happen if he doesn't find her?
