Oh, this is fun.
Coming out of the Krakoan era?
X-Men:
The only official X-Men book. They're in the driver seat and carry the main story of the X-franchise. Pure heroics.
- Main: Phoenix, Rogue, Polaris, Sunfire, Thunderbird, Mirage, Bishop
Hellfire:
A shady "goodwill" title, clean-up (/cover-up) for mutantkind across the globe. Politically charged action.
- Court- Emma Frost, Iron Man, Xavier, Destiny, Exodus
- Field- War Machine, Mystique, Penance, Sabra, Armor, Gentle
Marauders:
Street-level, essentially. More seedy environments and enemies. A noirish Fight Club.
- Psylocke, Talon, Gambit, Cannonball, Jubilee; Blade, Misty Knight, Quicksilver
X-Force:
AKA The Hounds, AKA The Pack; Black-ops and beers. Friends and enemies join and bond over the shared trauma of horrors committed by their own hands. All here gain asylum, redemption, and family at the cost of taking out the most vicious threats.
- Main: Wolverine, Shadowcat, Beast, Domino, Frenzy, Deadpool
- Support: Deathstrike, Sabretooth, Wild Child, Grizzly, Catseye, Feral, Thornn, WolfCub, Catiana
X:
Global, galactic, and dimensional threats.
- Storm, Iceman, Manifold, Colossus, Magik, Synch, Legion
Uncanny Avengers:
Unity squad.
- Captain Krakoa (Cyclops), Captain America, Scarlet Witch, Captain Marvel, Firestar, Captain Britain, Nightcrawler
House of M (spun out of Scarlet Witch):
A true royal family of the Marvel Universe, focused on uniting all superhuman affairs. Scarlet Witch represents the Avengers, Quicksilver represents the Inhumans, and Polaris represents the X-Men. I see this as a Game of Thrones meets Bladerunner
- Scarlet Witch, Quicksilver, Polaris
- Others: Black Panther, Crystal, Sunfire, Namor
- Support: Joseph, Wiccan, Speed, Luna, Viv; Vision, Hulkling, Medusa
