From the back of today's X-Men Blue #16, a tease of something to come…

At least two new ongoing series from the Xbooks? Well one of them, possibly the unexpected one might be X-Men: Red, the new team book with the returned adult Jean Grey taking the lead.

But the return of a fan favourite? Well, the New Mutants movie is coming soon. But we have a Cross-Time Caper in today's X-Men, so could that be Excalibur? Then there's always X-Factor, X-Force, maybe even X-Babies! And it may be more than one…

What would your returning X-book fan favourite be?
