First appearance: Mighty World of Marvel #7, 1983. As a mutant human, she was born during a blizzard, and adapted to the weather by growing special fur. She fell in love with Brian Braddock, the former Capt. Britain, and they were married for a time.
Current status: unknown since House of M.
Was subjected to the following acts of discrimination: she had a rather strange upbringing as a child, being naïve and detached from reality. Because her parents were scared that she’d be persecuted (she was born near the site of an ancient British castle where dark magic was said to dwell), they hid her in their trailer where she watched a lot of television, and thought that Gerry Anderson’s world on television was real. Later on, during House of M, to stem a tidal wave of multiple realities coming from the Omniverse, she sacrificed herself to stop a lot of the chaotic energies coming from it.
What’s wrong with how this was done? House of M, which was an extension of Avengers: Disassembled, is just as awful as the previous miniseries and crossovers connected with it. By tossing away Meggan, that’s one of the ways in which Marvel has paralyzed character development, and, just like the One More Day story in Spider-Man, they threw out some good potential for really exploring the relationship of a married couple.
Brian Braddock as well as his sister Betsy, are now, for all I know, stuck in the paralell realities seen in Exiles, and I doubt that much could come from that.
