Neutral: Pros

The Civil War comics had two sides conflicting over the Superhuman Registration Act – just like the movies will – but they also had a neutral onlooker.

That neutral onlooker was Doctor Strange and, given that Benedict Cumberbatch’s character is not set to appear in Captain America: Civil War, someone else might be that neutral onlooker.

Scarlet Witch fulfils the magic-based character role that Strange would have taken and, as such, may end up taking his role – and that’s probably the strongest argument for her being neutral (such is the level of her power that she could potentially use it to end the conflict peacefully).

There is also the simple fact that, unlike the other heroes, she might be reluctant to turn against either of the two men (Captain America or Iron Man) that she fought alongside in her home country of Sokovia against the evil robotic villain Ultron.
