This one is simple:
You’re talking with someone who is COMPLETELY unfamiliar with Marvel (comics, MCU, media or otherwise). Somehow this person has never seen or heard of Marvel in any way.
After talking for a while, you land on the subject of Marvel and, when this person asks you about some of the characters, they take a particular interest in Rogue. This person asks to see a picture of her and you realize this will be your one chance to show them an image that will sell them on how cool Rogue is, and maybe even Marvel as a whole.
Assuming you only have this one chance, which SINGLE IMAGE of Rogue would you show them? You only get to select ONE PICTURE. Make it count 😉
