Generally speaking, he was an impeccable piece of craftsmanship. Loki was an almost perfect replica of the man he was built to replace, an AI-android as sophisticated as Vision without the added power of a Stone. There were flaws of course: he was slightly less durable; his memories of his early life kept only to what his maker had known with the rest invented; his ability to harm and his lurking malevolence banished; his ‘magic’ was limited to changing his appearance and a few light projections; and that feeling that came from the presence of a god could never be fully copied.
And Loki knew he was not the original, but he did not mind; was not programmed to. He knew his purpose and was content with it, never more so than when he came truly alive for the first time and looked his master in the face.
“Hello, Stark. Did you miss me?”
