"STARK!" Said scientist looked up from his work, Bruce joining him.
"What is it Loki?" Thor's brother was staying with Thor in the Avenger tower. It had not taken long for the mischievous alien to find the so called "prank master," Tony. Both defending their honor, they had descended in a prank war. This was Tony's first prank, but it had crossed a line.
"Explain this!" Loki held up a picture and the rest of the Avengers who were in the kitchen for breakfast started cracking up, none trying to hide it. Except Loki and Thor weren't laughing.
Loki held a picture of a poster that was found in China, but quickly spread all over the internet. It was a rather disturbing one of Thor and Loki hugging in a not-so-brotherly way.
"It was my turn." Tony tried to keep a straight face, but failed horribly. He was just so impressed with his own genius.
"This is so wrong I don't even have words." It was Thor who spoke this time.
Clint and Natasha were still laughing, even harder every time they thought of it. Bruce and Steve were politely attempting to cover their mouth. Tony just looked proud through his fits of laughter. Loki and Thor glared. "Take this down, Stark, or I'll change this to you and the Hulk."
That got their attention. Clint laughed even harder. Loki turned and snarled at the archer, "Shut up, or you and Coulson are next."
"Anyway," Tony said, "we agreed that we wouldn't hold back when we began, Loki."
"Very well," the demigod sniffed.
...
By lunch, the Avengers were laughing at something new. All of the billboards in major cities had been replaced by an image of the Hulk and Tony (without his suit) in an odd embrace that made onlookers feel weird. By lunch, various reporters were swarming the Avengers tower, asking for Stark's opinion.
"LOKI!"
