My dream roster would have to be:
Kitty Pryde
Lockheed
Magik
Nightcrawler
Rachel Grey
Cyclops
I always like a smaller group for teams, no more than seven members and if we count Lockheed as part of the team but not as person who sits in a chair, and takes up an extra place at the table, I would throw in
Emma Frost
Wolverine
Those seven have never made up a team together, which isn’t too crazy as they have been in different places throughout their tenure of being members of the team. The only real omission would be Storm as it is essentially a “friends of Kitty” with Emma thrown in there for chemistry. There is just something about Storm that is leaving me cold these days. And it isn’t like she is everywhere to me, I can easily do without her. And it isn’t like she is displaying a bold new attitude I don’t care for and I was all for Punk Storm in the 80s. Maybe it is that I’m not crazy about her and Wolverine being together.
Storm
Heck, I’ll just add her. Eight isn’t too many. Do feel tempted to add two more to make ten that is way too many.
Doug Ramsey and Iceman as alternates and to round out the team to ten.
Get two original X-Men, three All New All Different, Kitty, Lockheed, Emma represents the villain turn hero quota, (though we should stop referring to that era of hers at this point), two New Mutants, and people love seeing them graduate. to the main team,
Rachel is there to represent the future as an offspring, legacy character.
That team literally has someone on there for everybody! Lots of team dynamics and history with all the characters in one way or another. Pretty sure Kurt and Bobby have never been on a team together.
Beast
Shoot, now I want Beast on there as he and Kitty have some fun playing off of each other.
Twelve members would be something right? Like the Knights of the Round Table, or something like that. It may be the Greek Gods that I am thinking of. I just remember Morrison’s JLA hit 12 members and they were meant to relate to Mount Olympus.
I know the obvious choice would be Colossus but I would never add him to a Dream Roster of mine, even if he is in the 12th slot. Pete Wisdom wouldn’t work here. Angel and Jean wouldn’t work. If you add Rogue, I feel like Gambit would need to be in this.
Karma
Karma is the perfect choice for 12th, can’t believe I didn’t think of her sooner.
Three New Mutants on the main team, that would excite some people.
Kitty Pryde / Lockheed / Magik / Nightcrawler / Rachel Grey
Cyclops / Emma Frost / Wolverine / Storm
Doug Ramsey / Iceman / Beast / Karma
Not a horrible team, they will need a pretty decent base. Pending on how Battle of the Atom works out, either this team has no chance of forming or a high chance of maybe one day forming.
That is far too many characters but I would be happy with any combination of seven of those.
As long as the core five made the team.
