1. After the battle of New York, Loki is punished by being forced to join/help the avengers. Isolated and hurt, Loki locks himself in a cupboard in his room and creates duplicates of himself. One to interact with the avengers and another to go out into the world. The first becomes a model, and the other helps out with an orphanage/group home. He is later discovered because tony decides to play laser-tag in the tower and an Agent shoots Loki's doppelgänger thinking he's attacking the avengers.
2. Loki is banished from Asgard and is homeless on the streets of New York. Guilty and desperate to make amends he gives everything he possesses away to others including food, clothing and a bed to sleep in. As winter gets nearer he runs out of things to give, so he decides to give his own life to help people in danger during villain attacks. Tony spots him during a mission where he saves a little boy from a doombot (or debris, can't really remember) and they take him to avengers tower. *FOUND* https://archiveofourown.org/works/6188860?view_adult=true *
