I've been saying for a while now that General Ross is the #1 contender for Red Hulk, and he has been since the release of #600 pretty much sealed the deal for me. But remember if you will my parting words about the coming of Red She-Hulk, and her identity.
It looks like I might be right.
Who else would have the dramatic impact that Greg Pak and Jeph Loeb both say she (and presumably her alter ego) will carry in to the book? Who else would shake up the status quo so much? Who else would have genetic traits that would allow her the same type of mutation as her father?
And who else would be a likely candidate who satisfies the requirement of being someone who has at the very least been referenced once during Loeb's run thus far? Domino, whose tattered leathers she seems to be wearing, doesn't fit the bill--she's not from the Hulk's side of the MU and hardly fits the paradigm Loeb has set up. She's a decoy and will reappear in #17, mark my words. Victoria Hand may have the hair, but hasn't been referenced in Loeb's run to any substantial degree and is not a Hulk character at the core (not nearly). Marlo Jones hasn't been seen or referenced lately. Jarella was shown as dead in #10, and that would be a game-changer, for sure, but the memories don't match up as she's not from Earth. Who else is a female from the Hulk's previous life? Kate Waynesboro is accounted for in Pak's book, while April Sommers, Angela Lipscombe, Susan Jacobson, and others are pretty much one-off characters, all unreferenced by Loeb.
No, the only outlier, who is from a later generation than Red Hulk (suggested by their conversation in #16), who's been experimented upon previously by MODOK, friendly with Doc Samson, and would really shock Banner, Hulk, and Hulk fans?
The only answer, friends...is Betty Ross Talbot Banner.
I said it before Red She-Hulk was introduced, and I'm saying it again now.
