Over a decade ago, Marvel Comics killed off Jean Grey. Since then, a younger version of Jean and the original X-Men were brought to the present in an attempt to discourage a mutant civil war.
Over the past year, a series of new X-Men team have formed: X-Men Gold (featuring Kitty Pryde, Storm, Nightcrawler, Old Man Logan, Colossus, & Prestige), X-Men Blue (Jean Grey, Cyclops, Beast, Iceman, Angel, Jimmy Hudson AKA Son of Wolverine, Bloodstorm, Magneto, Danger, & Polaris), and the Astonishing X-Men (Psylocke, Archangel, Bishop, Old Man Logan, Rogue, Gambit, Mystique, & Fantomex). Of the teams, I tend to prefer the X-Men Blue team.
More recently, we've learned that the older Jean Grey will be resurrected within the next few months. And more even more recently, it was announced that Jean Grey will be heading up a team of mutants with a new X-MEN RED comic book title.
Earlier today, Jean Grey's X-Men Red team was announced and I'm... vaguely interested. X-Men Red consists of Jean Grey, Nightcrawler, All-New Wolverine (AKA X-23), her sister-clone Gabby, Namor the Sub-Mariner, Gentle, and a new mutant named Trinary.
Don't get me wrong. I like Jean. I like Nightcrawler. I like X-23. And I like Namor. I'm curious to learn more about Gentle, but not as a team regular. Gabby has X-23's powers so we've got a duplicate member. And we know nothing about Trinary. So we'll just need to wait and see what happens.
