Show him the drow thread and ask him about that LA...
Fast Healing +5 at low levels... that char is nearly unkillable (ok, a orc barbarian in rage with twohanded PA will kill him).
He wants to play a fightertype, with LA he lacks HP, that does not work. Wolverine himself is a huge bundle of hitpoints, in addition to his regeneration ability.
I'd go the bbn/dragon (perhaps 3.0 apprentice levels for level 1) shaman route with Rapid Metabolism as prerequ and Niffts Imp Uncanny Healing. That way, the char has Fast Healing 2 at level 1 if he's badly hurt (I don't think that's too broken). Allow him another Feat at level 3 that increases the Fast healing (4 below half hitpoints, 2 above).
That way he has a char that is hard to kill but cannot do anything but rage once per day and heal (himself fully and his buddies a little bit). You still need a way to get his claws... and he doesn't have many skillpoints for the whole jumping/climbing stuff Wolverine likes to do.
