Tony Stark was the most popular kid in the 3rd grade, no doubt about it. It was no wonder; his dad was rich, he had a pretty girlfriend, Pepper Potts, and was extremely charismatic, even for a 9-year-old. Everyone knew who he was. All in all, his life was, what you might say, perfect.
On the flip side, Steve Rogers was the new kid. Having moved from a rather old-school town, he wasn't exactly up to date with certain trends and fads. He was a lot shorter and scrawnier than all the other boys, and he was almost always getting sick, though he hated missing school.
Thor and his Loki Odinson were both also fairly new, from Scandinavia, hence the names. Thor was large and boisterous, whereas Loki was lanky and quiet. Thor, though loud, was generally well-mannered, but Loki was utterly mischievous. They were so different, not many people even knew they were related.
Natasha Romanoff was from Russia, though she didn't have an accent and no longer spoke Russian. Her closest friend, Clint Barton, had befriended her when she moved to America, and the two were practically inseparable.
Lastly, Bruce Banner was known for his anger issues. He hadn't actually had a tantrum since before grade school, though when he had he had practically transformed into a different person. The normally shy, quiet boy had been throwing chairs and over-turning tables. Practically everyone was afraid of him, except for Tony, who had been sick that day and since then had desperately wanted to see him angry.
These six had practically nothing in common, until Loki decided to make trouble.
((This is mainly just a filler chapter, actual plot next time! Also, I'm wondering if I should leave lil' Steve 'Pre-Serum' or not... :/ Anyway, tell me if you see anything weird so I can fix it!))
