Wolverine once tried to cut down Stryfe (the Cable clone) but was totally ineffective. At which point Stryfe told him that his claws were totally ineffective against against a telekinetic shield. (This was when the X-men, and LAdy DeathStrike, went against Stryfe after he got control over codes used to activate Omega sentinels). <p> Jean Grey is also a telekinetic (among other things). Wolverine would be totally useless against her in a direct confrontation.
Jean Grey. Wolverine has a strong durability against mental probes/control, but to neutralize him such as turning his mind off or knocking him out, she is surely capable of doing it. Also, if Jean was a threat, Wolverine would surely not hesitant too much to take her out of the picture (look how he administered assisted suicide for his former loves, such as Mariko or Charlemagne).
