After Kenshiro has learned that Jagi is the reason why Yuria and Shin are gone, Kenshiro makes sure that Jagi does not walk out alive.
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 his body keeps fighting until all of his blood starts to spill out, reflecting the clouds above in a big pool.
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.
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, beated 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 mmoments in the manga was starred not by Ken, Rei or Raoh... but by Lynne. 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 ordererd swearing allegiance, she refused firmly and started to walk at the grill on her own.
Lynne: 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 vows,upon seeing Lynn bleeding, that the last thing their foes will see is their own gushing blood.
