Quicksilver can be in both Avengers movies and X-Men movies because he has been in both Avengers comics and X-Men comics. Quicksilver and Scarlet Witch were members of the Avengers for a long time, so even though they are mutants, children of Magneto, and former members of the Brotherhood of Evil Mutants, they can still be in Avengers movies.
