Here's one Mirage I wish would disappear!
If you don't remember Mirage... well, good for you. She comes from the New Teen Titans Annual #7 (1991); note that, as a general rule, any character introduced in any Annual is either slapdash, cheezy, or just plain wrong.
Let's send her to Marvel where she'll be fine. Why, you ask?
She grew up a street urchin in Brazil. I bet she even picked a pocket or two; sound familiar?
Instead of having a name tangentially evocative of her power (like say, "Gypsy" or "Spellbinder"), she is named, in the Marvel tradition, directly after the power itself: Mirage.
She was created only to complicate the social dynamics of Wolfman's Marvelesque New Teen Titans, where, in a typical Marvel "supergroup as dysfunctional family" plot, she fell for Nightwing and impersonated Starfire in order to be with him (didn't Mystique do that?). A sleeper agent like Terra, she found herself torn between good and evil. Oh, and she's a single mother (of course).
Another morally ambiguous, self-tortured, self-conflicted imperfect person with a one-note power, family difficulties, and unrequited love = Marvel. Danielle Moonstar, move over!
Joe Quesada, Mirage is in the mail!
