5) Lilandra
Now that the Marvel Cinematic Universe has explored its cosmic side to great success with Guardians of the Galaxy, the X-Men franchise should do the same. If they did, the character that could embody this shift into sci-fi would be Lilandra.
Forget his fling with Moira McTaggart, space queen Lilandra is Professor X’s greatest love – the pair share a lifelong psychic bond, don’t you know. They were even married until Charles mind-controlled her when he himself was possessed by his evil twin Cassandra Nova (again, don’t ask).
Fans would love to see the space-based elements of the X-Men comics brought to the screen, so hopefully Fox take note of this in future – Lilandra’s romance with Charles proves that there is dramatic potential in it. She also played a part in the comics’ Phoenix Saga, which they really need to give another go on the big screen.
