I’ve noticed that Quicksilver and Scarlet Witch are in the new Avengers movie ages ago and I’ve been wondering why they’re there since they’re X-Men characters I think. I’ve read they’re Magneto’s kids and that actually Quicksilver was in the recent X-men movie but I know Avengers and most of of…
Quicksilver and Scarlett Witch were first members of the Avengers. when they were initially introduced there was no mention of them being mutants or anything, they had no back story, they were just Avengers. It was much later that they were officially declared mutants and it took almost 15 years of publication before Marvel made Magneto their dad.
So technically Marvel had just as much of a claim to the characters as the X-Men franchise did, in fact Joss Wheadon said that he intended on using the characters almost two years ago.
X-men: Days of Future Past never initially included Quicksilver in the script, it was actually supposed to be Juggernaut, but when they found out that The Avengers were going to use the character they did a quick re-write and shoehorned the character into their movie just to say “they did it first”.
While it definitely worked in the movie, The Avengers did have the characters marked first and due to some iffy legal reasons both studios can use the character.
About that first point
They were definitely mutants and in X-Men comics first.
Uncanny X-Men #4 March of 1964 vs, someone correct me if I’m off on this one, The Avengers #16 May of 1965.
The reason they could be seen as belonging with the Avengers “more” is because of how much time they spent being Avengers, it’s definitely not because they were Avengers first.
I’m curious about this supposed writing over Juggernaut of all people in that role, because that would had to have been massively different… and probably would have erased his relation to Xavier. (Did the movieverse even ever touch on that ever?)
