There's sites that have anime clips online.. I think Crunchyroll and Kumby are a few. At least a few of them should be legal like Hulu, and the ones that aren't..
Well, there's no law against watching a stream. Only against uploading it.
And that's all I'm going to say on the topic. ^_^;
The manga is the one to get if you want purely canon feats, though. The animes that exist are awesome, but remember they have a ton of filler.
True Rei could literally spool the flesh from wolverines bones in the first 5 seconds of the fight.
In the world of hokuto no ken wolverines only advantages are his healing factor and his adamantium skeleton. There are plenty of guys who dwarf him on skill strength speed and technique.
The manga describes the techniques as transferring ki into the pressure points, and the effects could be instantaneous, or they could happen over time.
I'm guessing with the faster working techniques, Wolverines muscles explode like anyone elses. If Ken tried paralyzing him or using exotic techs, those might fail though...
Kenshiro did have a kind of "dial a power" thing going though.. Basically, he could do anything from making muscles stronger/weaker, to reprogramming someones mind, to making someone tell the truth against their will, to reversing the effects of poison, to regenerating someone from near death to perfect health long enough to finish a fight, and even brought someone back to life by the end of the series (Or appeared to).
The way he pulls stuff out of his rear, I could see him having a tech that stops healing.
These guys^^ would annihilate any street level characters in Marvel and Dc combine, period!
Kenshiro would KO Wolverine with one blow, wolverine HF would be the only thing that will keep Logan from dieing permanently, Gees Raoh and Toki would rape Logan, Sabertooth, Lady death strike Omega Red, Captain America Batman, Deathstoke, Karate Kid so damn fast it wouldn't be fair!!
