ResurrXion (2017): It's a brand new day but there's some old familiar faces on the horizon. Not only do the young X-Men take down old Generation X foes Black Tom Cassidy and Juggernaut (who gets briefly banished to a dimension that could be like Emplate's pocket dimension, but is referred to as simply Hell), but Emma Frost & Monet also appear in issue #1 on screens behind Magneto as two of his future targets for his team of X-Men, with Monet likely being one of the "comrades who have lost their way" since Monet was most recently on Magneto's Uncanny X-Men team right before ResurrXion; Emma Frost could also count as losing her way, as she's gone a little crazy after losing the adult Cyclops in the IvX (Inhumans vs. X-Men) event. To top it all off, in the Coming Soon section of issue #1, there was a panel of Chamber, Jubilee, Mondo, Skin, and Synch, meaning the young X-Men would meet some version of Volume 1/Classic Generation X heroes at some point. For Generation X fans, this tease comes to fruition in the time-traveling arc in issues #16-#20. The teenage original X-Men figure out that their presence in the present is screwing up time, so they use a time machine Magneto built to send themselves back to their own time, but they end up skipping through time instead; it's in issues #17-#18 that they come across an alternate "recent past" Generation X: Penance, Husk, Synch, Skin, Chamber, Jubilee, Mondo, and Monet being raised by Sean Cassidy and Emma Frost in what is pretty much a refugee camp after the X-Resistance lost to the original X-Men, who have turned on mutantkind for some unknown reason. In the initial battle, Monet and Penance are the only ones able to resist Jean's telepathic stun; later, the students all hang out together in the rec room talking, until it's revealed that the school has been destroyed and they've all been living in a Danger Room simulation. In issue #20, Generation X returns to help the X-Men take out the real time-meddlers: the Future Brotherhood of Evil Mutants; with that accomplished, this version of Generation X fades from existence.
~The Rest of the Issues~: In issue #6, there is a single panel of a woman wearing white drinking wine, described as an enemy who believes they're in the right; this is likely Emma Frost. In issue #7, in a Secret Empire (2017) tie-in, Emma Frost is featured in her role as part of the ruling body of New Tian; the strike force she sends against the X-Men: Blue team includes the likes of Mondo, Marrow, and Toad. In issue #8, the White Queen's mental instability is on full display as she tries to recruit the teenage Cyclops to the New Tian cause; Banshee briefly appears as an illusion during a fight. In issue #9, Emma's mental manipulations have paid off and the teenage Cyclops fights his friends; Mondo also returns as part of Emma's fighting force. At the end of issue #9, it is revealed that the White Queen, Miss Sinister, and Bastion were using New Tian to collect mutant genetic material for something called Mothervine (meant to create new mutants so mutantkind can be the dominant species, but under Mothervine's control), in a story that's continued in issues #23-#28; #31-#32.
This volume's story ends when the "Extermination" mini begins, then there's "Uncanny X-Men" (2018-2019).
