Xavier Institute Students
It was stated that there were 182 Xavier Institute students enrolled before M-Day (2006). They are now 26 including X-23 (plus Kid Omega in Beast's lab). The ones who did not show up in New X-Men, vol. 2 #23 (2006) are most likely depowered or even dead (42 died on the bus explosion in New X-Men, vol. 2 #23 [2006]).

Students with no squad known (2003–2006)
Here are the students who were shown but whose squads are not known or who died or left the Institute before joining one. It is likely that some of them were members of squads whose full rosters have not yet been revealed, including the Exemplars, the Excelsiors, the Paladins, Storm's squad, and possibly the Chevaliers.
