Awhile ago, there was a meme making the rounds (with Marvel's blessing, no less) wherein characters were shown in a picture with the words "Avenge the Fallen" overlaid. If the picture was in color, the character was still alive after the snap. If the picture was in black and white, the character had died.
The collection of characters in Dream Haven are not, obviously, a part of the MCU, and did not experience the snap. Even so, there are a few characters that are especially noteworthy in this set: Comet Girl is done almost entirely in black and white, except for her lips, her domino mask, and her emblem. Her author, Kittyelfie (who gave permission for her appearance, here,) can explain about her special circumstances.
Amaterasu also appears halfway between color and black-and-white; as an entity that contains the essence of her previous incarnation, but actually did die, I decided she deserved the special treatment.
Dal-Lii and Arachnia were commissioned by LoneStranger and included in this set with his permission.
