It was announced earlier today that Jean Grey's team of X-Men will include the All-New Wolverine, Nightcrawler, Wolverine's sister Gabby, Wakandan mutant Gentle, Namor the Sub-Mariner and a new hero, Trinary. “We’ve also got one more fan-favorite hero joining the team in this first arc,” said X-Men group editor Mark Paniccia. “As the threat level escalates, Jean needs to build a highly specialized team … not just those she trusts, but allies who can survive the oncoming storm.”

Here's the new description for Marvel's X-Men Red:

When one of the most dangerous X-Men villains returns to wreak havoc, Jean’s dreams of peace are threatened…and order starts to turn to chaos. It’s mutant against mutant this February in an all-new adventure that will have X-fans on the edge of their seats, as Jean Grey’s team takes on the Marvel Universe – only in X-MEN RED!

Written by Tom Taylor and illustrated by Mahmud Asrar, with covers by Travist Charest, X-Men Red will launch in February as a companion to the current X-Men Blue and X-Men Gold.

Jean will return in Phoenix Resurrection, marking the first time fans have seen an adult Jean Grey in the Marvel Universe since her death in New X-Men more than a decade ago. The time-displaced teenage version of the character has been a prominent part of Marvel’s stories the past few years, and stars in her own ongoing Jean Grey series.

Phoenix Resurrection #1, written by Matthew Rosenberg and illustrated by Leinil Francis Yu, is scheduled for release on Dec. 27.
