I remember Thor was punished by odin and sent to earth without powers and when he was captured by Shield when he tried to recuperate the hammer an invisible Loki followed him where he was interrogated by phil and clint to protect him since he didn't had his powers.
I've vaguely remember that loki turned clint's arrows into dicks but not sure if it happen in this one.
Im pretty sure Loki was not evil on this one but he had a fight with thor.
It's been YEARS since I lost track of the story. Im pretty sure it was a long story but i stopped watching is since it was incomplete at the time.
