No and if that happened in the movie, which I didn't see it's abosolutely noncanon.
I tend to mention the gaidens carefully and loosely. I don't like to base stances and arguments on them unless the scene plays out at least almost exactly like the original anime/manga.
That being said I didn't read the Jagi Gaiden and if he or anyone took a nuke then it's bad writing in my opinion unless it's like how it happened in the Toki Den.
Toki sacrificed himself since there was no more room in the fallout shelter and stayed outside in that little tunnel place. The world and everything was nuked but the bomb wasn't directly on him and I don't think any of the explosive force came his way. He simply stayed there for either days or weeks (Don't remember off the top of my head) without food or water due to his training and everything.
I also believe the gaidens are written by the original writers. Buronson Hara.
Meh, I'd actually give him the win over Jagi, Yuda, Shin, possibly Rei and Shuu. The only Nanto master I see honestly beating him is Souther and even then I could see Wolverine taking a win or two when given CIS.
At the end of the series no one else was in his league, but times when he was actually challenged and had to actually try were Souther, Shin, Amiba, Raoh, Kaioh, Hyoh, Han (one of my favorite fights)
[SPOILER - highlight to read]: If his brother Toki was healthy then he would've outshined and outclassed both Raoh and Kenshiro.

If you say it was done with this art style and Ken wasn't introduced until later then I honestly have no idea which one you're talking about, the only gaidens that were animated were Kenshiro, Toki, Yuria and the two Raoh dens and Kenshiro appeared fairly early in all of them I believe. The only time I recall him destroying anything by putting a hole through someone was when he used Tenha Kassatsu on Souther and that barely destroyed a little piece of the pyramid. Any idea who he did it to? Was the guy blonde, red hair, was is a grunt or prominent antagonist?
Rei's underrated, because of how Raoh dismantled him.
But I wonder if he'd do better against Souther than Ken did, given Southers trick won't matter against a style that doesn't use pressure points, but instead tears apart the body.
Raoh is pretty much it, considering he's really the only character that fought him on a level playing field.
Souther had a mutation that made his pressure points reversed on his body working in his favor, and Kaioh used some kind of demonic aura that messed with Ken's ability to target pressure points and keep his balance to gain an advantage, which Ken learned to overcome.
Toki "might" have been above both Ken and Raoh when he was healthy.
The main character of Fist of the Blue Sky, Kasumi Kenshiro might also be on Ken's level, but it's difficult to say. Kasumi never lost a fight, and he also fought someone who's pressure points were in different places and figured out how to counter that technique quickly, but this is because Kasumi claimed there's certain pressure points that can't be moved through technique. Souther is probably different, in that his pressure points were moved through mutation, so I'm guessing all of his pressure point areas were different..
Rei's not underrated in my books. Fact is that he's still far below Ken skill and strength wise.
No Nanto master could face or even beat Souther. Souther star was the Command Star and he was destined and set to rule over all of them. He was the strongest of the Nanto Roku Sei.
My personal ranking of the top masters from strongest to weakest
In their first fight Souther was cocky and only toyed with him because Ken didn't know of his secret. If Ken knew from the start and Souther didn't know he knew then he would've died. If Ken knew at the start and Souther knew he knew then he would've taken that battle much more seriously. Souther's the man and really took it to him though and even resisted the effects of Hokuto Shinken after having his pressure points hit.
Anyways, personally, I think Wolverines overmatched even by characters like Rei, unless we're talking about a Wolverine that could tank Hulk shots and heal up instantly from having his entire body incinerated.
Danny Rand is more than a match for Wolverine, and imo Iron Fist would lose to Kenshiro in an instant, so anyone that even makes him work up a sweat should be a challenge for a mid tier character (Mid tier occupied by the likes of Luke Cage, Iron Fist, Spidey..)
