1) Has been at the academy for some time, very well respected, but not seen often as he leaves the grounds frequently. He has a troubled past, and when he is here he doesn’t help out a lot. Rumors say he trains students in the Danger Room when they have shown ability.
2) Wolverine is very similar to the X-men Evolution write-up. No one knows he leads X-Force except members of the group.
3) It is hardly a secret Wolverine has killed. However a rumor is going around that he has even killed Mutants who he thinks may be to dangerous to keep alive. This has turned away some students, pushing them toward Brotherhood or Acolyte Organizations.
4) Wolverine takes a while to trust people, pushing him for information might be more than you can handle.
