Back Story: Wolverine's past is shrouded in mystery. (Ooo, do you like that set-up? I did.) Somehow, he was captured by a ultra-secret team of scientists in Canada and had an adamantium skeleton inserted into his body. (He survived this because of his regeneration ability.) It was the beginning of a project called "Weapon X", of which he, Sabretooth, Maverick, and Wraith took part in (the latter two never actually showed up in the series; they were only briefly mentioned). It was to make them the ultimate Mutant slayers, although the Scientist who revealed this never really expanded on the idea. Of course, the original X-Men comics go into more detail over this, but this isn't the original series, so I didn't assume anything until it was made fact in the show. Wolverine, being an unwilling subject, broke free, and, of course, kicked mad scientist booty. It's unclear as to exactly when this took place- Wolverine's healing ability makes him age very slowly, as he's at least been alive since the early 1900's. Both before and, presumably, after the Weapon X project, Wolverine was part of a secret government agency called S.H.I.E.L.D. Among other assignments, Wolverine worked briefly with Captain America in World War II, helping free prisoners of war and whatnot from the Nazis. Eventually he quit, however, and was the second X-Man to join Professor Xavier's team (if you go by the X-M:E comics). And the rest, as they say, is history. He still is haunted by his past, though, and doesn't seem to remember much of it. He's also recently gone through a costume change for Season 3, presumably to make him look closer to his movie persona. In Xavier's "future visions" at the end of the series, Wolverine is mysteriously absent from the X-Men roster, for reasons unknown.
Personality: Wolverine is a loner in the strictest sense. Although he's a member of the X-Men team, he works alone in most cases. He's far older than everyone else on the team (although he doesn't look it), and has a completely different personality than most to boot, so he doesn't get along with others very well, although he still tolerates them. He's generally short-tempered, and doesn't talk a whole lot. As such, he's mostly in the background, except on episodes that focus directly on him (which, admittedly, are relatively many in number given that he's an adult X-Man). Although you won't get him to say so, because of his "tough guy" image, he has a soft spot for the kids at the Xavier Institute, and would put himself in the line of fire in a split second, if it would save the young'ins. He has a real hatred against Sabretooth, though, and it sometimes consumes him. More than once he's left the people he would normally protect to go and take on Sabretooth- but other than this obsession, he's generally a nice, if somewhat stone-faced, guy. Wolverine has also made a sort of special tie with Rogue, since he has also gone through similar "I-don't-know-my-own-past" events and he also helped her through the tough events of "Self Possessed".
Final Reflections: I'm one of the few people I know who prefers the X-M:E Wolverine over any other version. I guess it's because the new Wolverine isn't nearly as nuts, I suppose. Although he still can get pretty feral on certain occasions (especially those involving Sabretooth), and tends to growl a lot during fights, he's much calmer overall than his old version. The original Wolverine was kind of a livewire, always ready to fight even if it wasn't the best thing to do in a situation. The new Wolverine tends to still be a "tough guy" loner, while not being as completely devoid of all sense as the old one. He seems to analyze most situations in his head before jumping into them. Also, because Jean Grey is far too young for him in the Evolution series, Wolverine isn't even remotely interested in her-- which is fine for me; I never liked the old Cyclops/Jean Grey/Wolverine love triangle anyway. Wolverine did get too much focus in the series for my liking, though, especially since his past is far too complicated to ever be adequately explained in a series that didn't focus entirely on him. Still, in a way I liked the lack of focus, given how everything else X-Men lately has been WOLVERINEWOLVERINEWOLVERINE.
