Are You A Boy Or A Girl?

''Uhh... err... hmm... oh... I... I don't know.''

This happens a lot with characters who wear something over their face that shields their identity, have faces and body figures that aren't masculine or feminine, and who just don't have straightforward appearances as a whole. One of the most popular examples of this is Metroid's Samus Aran, who was a Guy Who's Actually A Girl.

The gender reveal of the person in question could shock many people in both the media and in real life.
