Set during the Avengers
"You want me to put the hammer down?" Thor roared, batting Tony away. He swung at Steve, who tensed, but before he hit his target, a mass of...something slammed into him and knocked him backwards.
Thor righted himself and stared at the creature. It was large and fat, belly protruding above sagging trousers. Its misshapen face peered at his own and it waved a large club around aimlessly.
Two more creatures appeared from the trees.
"What the hell are those?" Tony yelled.
"I-I think they're trolls? I read about them in myths" Steve opted for the more diplomatic approach. He walked up to the leader. "Um, we're terribly sorry for trespassing in your woods. We promise to fix all the damage and- -"
The troll didn't even look at him, instead turning its face up to the jagged cliffs. Thor followed its gaze and glared at his brother, who had yet to move.
But the look on Loki's face told Thor that he wasn't involved in the appearance of the creatures. He almost seemed rooted to the spot in horror.
Then the three trolls attacked the mountain, clambering up at high speeds.
And shouting "DADDY!" at the top of their lungs.
"Brother," Thor began as Loki meekly followed them to the helicarrier, looking embarrassed and worse for wear.
"What the hel did you fuck this time?"
Loki's response did not ease Thor's nerves in the least.
"Leave my daughter out of this!"
In Norse mythology, Loki literally gave birth to trolls XD
RnR!
