We know Hans appears in a signal of "Wanted" in the commissary in Big Hero 6. Just a simple cameo? I don't think so.maybe Hans was not a prince, maybe he was a great and rich criminal (like Artemis Fowl XD) who conspired with someone (maybe Krei) to make a machine to travel in the time to the past, to scape from the justice (do you really think Krei is a good guy?). But only Hans could escape, leaving Krei behind.So, this show us some doubts: Why Hans traveled to a time so far? Why he didn't come back? Why everybody think the Robinson's machine was the first? (did I tell you I think Meet The Robinson and some movies more that have not anything with this theory are in the same universe with BH6?) Well, the machine was a secret, did it? why Krei would tell anybody about that?BUT THERE IS MORE:Why the Lee Family (Fred's family) has a statue of Hans?well, I said Hans was rich. If he had not only one partner (Krei)? If he had two?Stan Lee (Stan Lee, if you're reading this, this theory has not nothing with you, is the Stan Lee from the movie), Hansel and Krei wanted something... something big (but we don't know what)... but they were not just companion... they were friends. When Krei and Hans tried to escape to the past, Stan abandoned them, because he already had a son and a wife. And he decided to turned into a superhero to offset the terrible things he did in the past as criminal.When Hans traveled to the past, and never come back, Krei told Stan what happened him, he asked to make a statue of his friend.Krei started to design a new secret machine, to bring back Hans: the Project Silent Sparrow.He disguised the experiment for a teleporter, and when he sent Abigail to the portal, she went to the future, to the end of the universe. Or maybe she went to the past, before the Big Bang, when there was not universe. Because of that there was not gravity.But now the machine is destroyed. Let's think in the books about history (I mean, the books for study and school, you know) appears Hans, and Krei and Stan discovered what happened with him. Do you really think Krei and Stan will leave their friend in the past?They will build another machine, and, this time, they will make it in a way that it will work.What do you think our heroes will do?(I'm sorry if my english is a bullshit, it's not my maternal language).
