For the 5+ headcanons thing: AUTOMATON LOKI. i need more lil tidbits about them.
1. The dwarfs created Loki to be able to perform simple movements, mimicking how Aesir move .When they present their wonderful creation to Thor, they have Loki wound up so he will bow to the Prince which Loki does, but he also raises his head up and stares at Thor throughout which is not what he was supposed to do.
2. Thor is amused by the present, especially when he realizes that Loki is meant to be a doll, something to admire and show off to people, but not to touch. Why would anyone bring such a gift to Prince Thor? But he knows the dwarfs did it because people will come to see Prince Thor’s amazing moving doll and be so delighted by the dwarfs work that they will commission them. Once people have got enough of gawping at this invention, Loki will be forgotten.
3. Thor finds himself talking to Loki as if he were a real person. It is small things at first - complaining about how guests have asked to see Loki, or apologizing that he must bring Loki out once again to perform his tricks. It’s all joking at first, but Loki turns his head or offers his hand and looks at him in such a way that Thor begins to believe Loki really does understand him.
4. Once Loki begins to speak, there is a great faction of the court who believe he is a weapon sent to kill Thor and that he should be melted down before he can complete his mission. Thor refuses. Loki also refuses, but Thor’s word caries more weight since no-one but Thor views Loki as truly alive.
5. Loki is both proud and sad about being the only one of him in the whole universe. The dwarfs never are commissioned to make another. Sometimes, he thinks, it would be nice to have another person who understood what it was to be eternal magic inhabiting metal.
