I was wondering for a long time if there are any of the regular X-Men that were never on the same team. With regular X-Men I mean X-Men that are regularly on X-Men roosters, not the ones who joined once or twice.
So including the O5, ANAD team, Betsy, Rachel, Gambit, Rogue, Xavier, Magneto, Bishop, Havok etc
Not including Sunspot, Sage, Maggot, Firestar, Cece Reyes etc.
