Toxic T-mist cloud of Death.

[Darth Phoenix]

We know it is going to show up. After the killing of Avalanche for the Axis deaths are likely on the way. Who will Marvel Red Shirt before X leaves for off world. Your 3 guesses and who might be immune or stay 3 guesses.

Culls
1Husk-It would affectCannonball thus Avengers
2High Tide/Loa all Atlantain Mutants-a clenseing to streamline Movie Rights
3random Morlocks - Often victims of culls

Immune might stay on Earth
1X23-healing factor
2Penance-truly indestructible
3Cosmic Angle-cosmic upgrades

Have fun and let us see if we can figure out who Disney/Marvel wants out of the way.

Culls:

Hellion- easy to replace angsty psychic
Sunspot- opens up so many possibilities with AIM, Avengers, Hellfire Club and New Mutants team mates
Surge- they never use her anyway

Stay on Earth:

Martha- brain in a jar would be protected
Squirrel Girl- they want us to forget she's a mutant as it is
Pete Wisdom- just to much snark to let a little bio-weapon chase him away

[Master of Sound]

Culls:
One of the former Acolytes
One of the current students
Magma (they never use her anymore)

Stay on Earth:
Iceman (protected by Iceform)
Armor (protected by her armor)
Cecelia Reyes (protected by forcefield)

cull
-one of the WATX kids
-one of the New X-Men kids
-a Gen Xer(sadly its like tradition now, Im worried for Husk and Penance, and yes I know Penny shouldnt be affected being invulnerable but this is Marvel they never care for "logic")

stays-
-Jubilee-vampire
-Chamber-no lungs
-one of the more popular with writers X-kids like Pixie or Quentin.

[Myetche]

All teenage X-Men not associated with Xavier, Magneto, or Wolverine (too many to list)

[berserkerclaw]

It's not confirmed anyone is going off world. That's not a fact

I thought the whole off-world thing was Remender's idea?

Cull
Firestar I feel like she was brought around to be disposed of.

I could see this two. i think Marvel is going to whant to show this event hurting Avenger morale not just killing mutants.
If they do this and give us no reaction from Emma. I will be annoyed.

Neither was the Xmen living in Apocy's old ship when they were in new York during Axis but we guessed that before.

Even if they do not go off Earth the mist is hinted to have deadly effects so the Red shirt guessing game is still fun.
Mostly since I enjoy when fans can figure out how Marvel thinks. If you would like to guess it would be welcome.
