Many of Toki's moves are incredibly fun to watch, and are completely painless to experience. This move in particular, the North Star Humanist Face Breaking Fist, involves him firing pressure point-activating beams from his arms akin to Ultraman!
In the second storyline Kenshiro taking a huge chunk of out of a hill to plug a breached dam that was blown up by three mooks of Yuda (as high of the dam) and bitch-slapping two mooks who blew up the dam with it (after causing the Elite Mook leader of the group to asplode a short while before) then plugging the breach with said chunk of hill. See the Crazy Awesome entry above for a 3rd example.
This was only a background event to Rei's epic showdown with Yuda. While Rei's death is by far the most Cruel and Unusual Death any of the heroes suffer in Fist of the North Star, inflicted as it was by Raoh and his Hokuto Shinken, his final three days on the planet were just enough for him to finally take down his longtime rival and nemesis and pull one of the most awesome Screw Destiny moments in the entire series on behalf of Mamiya, the only woman he's ever loved, giving his life so that the Star of Death (which is normally an inexorable Portent of Doom for anyone who sees it in the Fist of the North Star universe) no longer appears for her.
When Kenshiro, Rei, and Mamiya team up, Kenshiro takes a nap, while Mamiya questions his choice to nap at a time like this. Suddenly, Kenshiro snaps awake reaches out to the side and catches a flying arrow headed straight for Mamiya's head.
Juza's last stand against Raoh. It's even more awesome in the anime where he, despite being killed by Raoh's Secret Technique, keeps on fighting (and even manages to wound Raoh with a single punch) until all of his blood starts to spill out, reflecting the clouds above in a big pool. What makes this all the more awesome is that he doesn't say a single word, but his eyes are very much open and alive. This is supported by his statement that his body moves by will alone, much like a cloud.
The scene in question from the vid, where Kenshiro rescues Lin from Zeed, is the first time that he busts out this move in the series, and it definitely qualifies as one of the first awesome moments of the series, as it establishes in a big way just what Kenshiro and his style of Hokuto Shinken can do.
Another iconic and awesome Hokuto Hyakuretsu Ken moment is when Kenshiro delivered that to Uighur, all accompanied with the awesome iconic music "Sentoo!", which also lasts in 38 seconds full if we count the build up (23 seconds if we just count the Hyakuretsu Ken, props has to be given for Akira Kamiya for keeping up with such high pitched "ATATATA" for that many seconds). Guess that's where the modern Jojos Bizarre Adventure take inspiration when they did Jotaro's ultimate beatdown to Steely Dan for 20 seconds...
The scene is even more awesome because Raoh started trembling in terror before the Musou Tensei, when until then he had treated Kenshiro as a capable but still inferior foe.
The first time Ken and Raoh confront each other. The first hint that Raoh is unlike anyone Ken ever faced is that he is an excellent practitioner of Hokuto Shinken. The second? The battle starts off with Ken and Raoh's spirits charging up and creating enough force to only... blow the two of them high up in the sky and start fighting there!
Kenshiro, beaten up by Souther, after having walked a desert for days, and receiving a sleeping pill, going to help Shuu and face Souther one more time as he recites again and again while killing mooks Shuu is calling me, Shuu is calling me...
One of the most impressive moments in the manga was starred not by Ken, Rei or Raoh... but by Lin. When the troops of Raoh raided the village where she and Rei's sister were -giving everybody the choice to swear allegiance to Raoh and be marked like cattle or be literally cooked-, she played bait to protect the older woman. When she got caught and ordered into swearing allegiance, she refused firmly and started to walk at the grill on her own.
Lin: I will not be loyal to you, demons! Never! Not matter what you do to me! Ken once told me when you let yourself down in front of demons, you are no longer human...
Villager: What a valiant girl! She'd rather die than become their slave!
And then Ayra takes a level in badass and shoots at least two bandits with a crossbow and then the men start fighting back.
And lastly Rei shows up and—upon seeing Lynn bleeding—vows that the last thing their foes will see is their own gushing blood.
Rei: WHAT KIND OF BLOOD FLOWS THROUGH YOUR VEINS?!
Lin consistently shows she has just as much courage as most of the anime's characters, moreso than most- when Shuu and his resistance have no leads to finding where Souther's forces are taking kidnapped children, she steps up and offers to become bait for the slavers, without even being asked.
Shin manages to get one is the dub version of the Hokuto no Ken movie. After he dies, Kenshiro acknowledges that SHIN loved Yuria more than Kenshiro did!
Kenshiro: You loved her even more than I did, Shin. No one can love or hate with more passion than a madman.
Raoh sends his entire army running for their lives after they kill Fudoh instead of him. What was previously thought to be a Badass Boast by Raoh was later shown to be a serious instruction, and that he should have been killed by his army instead for stepping back and over the line.
Tenshō Jūji Hō (Heaven-Soaring Cross Phoenix), the ultimate technique and only stance in Souther's Nanto Hōō Ken, is awesome to witness, involving him literally flying into the air and conjuring an image of a phoenix around him.
Souther and Kenshiro's final battle is just awesome in general. It's easily one of, if not the most vicious, climactic fight scenes in the series.
Doubling also as Heartwarming, the second half of the series starts with Bart and Lin battling against tyranny. In the first chapter of Part 2 they even fail in their mission to rescue some slaves (who were killed in the process in a gruesome death) and Lin had to confront a girl who was the daughter of one of the enslaved. They've been suffering nothing but setbacks and are so desperate as they don't even have Kenshiro along anymore to guide them..... In spite of that, they continue to battle to defend the weak and for the sake of justice in hopes of one day bringing true peace to the world. In the following chapters they both even willingly to walk into a trap to save some mere grunts. Just out of sheer respect for their fatherly figure and despite being regular human beings, they were willing to die. It was exactly the thing Kenshiro would have done, and this in spite of living for several long years even contemplating the possibility that Kenshiro might have been dead by that point.
Let's face it, Kenshiro is THE walking CMOA in general, taking on and defeating some of the most powerful and horrific villains ever put to paper.
The 1995 live-action film:
Ken saves a couple that gave him shelter from a trio of bandits. The first he kills by kicking his foot through a wall, the bandit's jaw is bent out. Much like a panel from the manga, the bandit tries to adjust it before dying. The second is punched in the back until his torso breaks. The last guy gets the 100 Cracked Fist move and while it lacks the traditional year or music power up it gets suspense as the bandit's head starts deforming and explodes off screen. Sadly, after that the filmmakers forgot they were making a Hokuto no Ken movie and Ken no longer has super strength and there are no special martial arts.
