Today, it was announced that Baron von Strucker will be in "Avengers: Age of Ultron", and he will be played by Thomas Krestchmann.
Now this news makes brings forward something that I was thinking about for a while now.
In the comics, Scarlet Witch and Quicksilver are the children of Magneto. But since Marvel Studios doesn't have the rights for any of the X-men characters, Marvel can't use the same origin story that the Maximoff siblings have in the comics. They will have to change it.
One important element to these two characters is the fact that they are Magneto's children, if you change that, you change the very essence of Scarlet Witch and Quicksilver. But because Marvel can't use Magneto, Scarlet Witch and Quicksilver lose one of their biggest elements. But in the same time, if Marvel doesn't even mention their father, then it's still ruins the characters. So, in this point, Marvel has only one choice.
Marvel is known to change things from the comics. Sometimes it works, and other times it sucks (The Mandarin). I think that if Marvel turns Baron von Strucker into Scarlet Witch and Quicksilver's new father.
So how this works?
In Avengers 2 we find out that Baron Strucker is the head of HYDRA. I have another idea in my mind, but I won't roll with it just yet. In "Captain America: The First Avenger", we see Red Skull being sucked into space. What if he was sent to our time. What if he travels in time, and finds himself in the 80's or the 90's.
Then he uses some kind of technology that makes his head not-red, and he becomes Baron Strucker. I know it doesn't sound that good, and so moving on...
Anyway, the original and more acceptable idea is that Baron Strucker is the head of HYDRA. After Red Skulls failure, Strucker looks for other ways to conquer the world.
Some how, Strucker gets his hands on a new piece of Tec that gives him powers. He becomes a major threat to the world.
In order to stop him, Howard Stark and young Nick Fury join forces and create S.H.I.E.L.D.
For years there was a secret war between S.H.I.E.L.D. and HYDRA, during that time, Strucker started to build himself a super army.
Years later, Strucker has a thing with a woman called Magda. Magda gives birth to two children, but dies at birth. The names of these children are Pietro and Wanda, who grow up and become Quicksilver and Scarlet Witch. They have superpowers from their father, so now Marvel don't have to say that they are mutants (because they can't say that too).
I really don't know what happens next, so I guess now we need to trust in Whedon.
