This document lists the team profile for “X” (mutant) teams from Marvel Comics, the order they should be read in, and what they’re about.
1963+ – X-Men
The core stories. Though for the first dozen years things could get a bit mid.
Era #1 – the 1960s and the original X-Men
This series covers the material as published during the 1960s. It also discusses why.
Organisation, roster, procedures, equipment and the start of the discussion about themes and story elements.
1963+ – X-chronology article
This article chiefly discusses how time passes during the original Claremont Run on X-Men. Which is useful since Claremont did not follow dominant usage in that respect.
It also covers those few indications of time flow in the 1960s run. So, all told, it’s an approachable explanation of how time passes for X-teams from 1962 to 1988.
1983+ – New Mutants
(We’re usually working per cover date. So by that reckoning the story was published in 1983. But the book was actually published in 1982, several months before the date on the cover).
The first spin-off team was launched during the heights of the Chris Claremont era of X-Men stories.
It had an almost entirely new cast, and veered more toward teenage drama and horror than the main X-Men title did.
Era #1 – the 1980s
Also called the “classic” era, though that qualifier sometimes get narrowed down to Chris Claremont’s writing run. That’s when the New Mutants made their mark – especially during the more experimental stretch when Bill Sienkiewicz did the art.
Team data listing, team creation, and earliest adventures.
Arrival of Warlock, the Gladiators story arcs, Asgard…
The rest of the The New Mutants vol. 1 run isn’t as well considered, so we’ll just cover it in two articles.
All the events from there to the creation of the original X-Force.
1986+ – X-Factor
X-Factor (named after the genetic “wildcard” behind superhuman mutations) originally was a new team made up of the original, 1960s roster of X-Men.
The book eventually lost steam, but was rejuvenated with a new roster and with a distinctive sense of humour wielded by writer Peter David.
Our one profile so far ain’t in chronological order at all. It covers the 2006-2013 era where X-Factor was a private detectives firm of sorts.
