''Ten no Haō Hokuto no Ken Raō Gaiden'' (lit. "Conqueror of the Heavens: Fist of the North Star Raoh Side-Story") is a spinoff of ''Manga/FistOfTheNorthStar'' by Youkow Osada, published in ''Weekly Comic Bunch''. The manga chronicles Raoh's rise to power as the Ken-oh, the King of the Fist, as he helps form an army with the help of his childhood friends Reina and Souga. It was adapted into a 13-episode anime series, which was released in English by Creator/SentaiFilmworks under the title of 'Legends of the Dark King: A Fist of the North Star Story''.

----
!!"Tropes of the Dark King":

* AdaptedOut: Jagi and Amiba are nowhere to be seen in the anime, despite having their own arcs in the manga.
* AnArmAndALeg: Souga loses his leg whilst escaping Cassandra.
%%* BadassPacifist: Toki.
* BerserkButton: Toki may be dying from radiation sickness, but can still fuck your shit up it you harm innocent people.
* CoolHelmet: Raoh. Uighur's modeled his own helmet after Raoh's own.
* CoolHorse: Raoh meets Kokuoh-Go during this series, earning not only his loyalty, but the loyalty of all his equine subjects, who become the horses of his army.
* CrapsackWorld: What did you expect? It is ''Manga/FistOfTheNorthStar'', after all.
* DeadGuyOnDisplay: The skulls of Igor the Lion King and Rize the Thunder Emperor are made into wine glasses for Raoh's victory party.
* DeathGlare: Raoh. So much so that even [[Literature/ASongOfIceAndFire Tywin]] [[Series/GameOfThrones Lannister]] would run away in terror.
* DistractedByTheSexy: How Sakuya does Gaoh the North King in.
* DramaticDeadpan: Now you see where Kenshiro gets it from.
* TheDreaded: Remember how Raoh in the original series was feared throughout the story and was described as this immensely powerful threat? This time, it's ''Kenshiro'' who reprises Raoh's infamy. The cast, especially Toki, even warns Raoh about his eventual meeting with Kenshiro.
* DualWielding:
** Reina and her twin blades, hence her nickname, Reina of the Twin Blades.
** Uigur and his dual bullwhips.
* DungeonBypass: How does Raoh and his two subordinates get inside Cassandra without triggering the death traps? Raoh simply punched a hole in the wall.
* EvenEvilHasLovedOnes: Raoh to his brother, Toki.
* EvilSoundsDeep: Raoh, in both his English and Japanese voices. Especially the English dub, as his voice was done by Andrew Love.
* HalfTheManHeUsedToBe: In his first big moment of pure badassery in the series, Raoh punches the leader of the biker gang – and the building behind him – ''in half.''
* IFightForTheStrongestSide: Yuda, as his loyalties go from Raoh to Thouzer on a whim.
* KnowWhenToFoldEm: Those smart enough to surrender to Raoh's forces without a fight.
* LargeAndInCharge: Some of the warlords tower over the nearly 7-foot Raoh. But just like [[Manga/FistOfTheNorthStar his kid brother]], size means squat.
* MadeOfIron:
** So much so that Raoh took a mule-kick from a stallion ''the size of an elephant.''
** Honorable mention goes to Uighur. Not as impressive as Devil's Rebirth, but the fact that he survived 5 executions under Gion's watch is impressive.
* MercyKill: Raoh deals one out to a mortally wounded foal which Kokuoh-Go was protecting. Reina is appalled, thinking this to be a KickTheDog moment, until Souga explains that it was already mortally wounded and that Raoh did not cause it any pain when he killed it.
* MissionFromGod
* CarFu: Raoh wastes a shitload of mooks with a motorcycle.
* NamesToRunAwayFromReallyFast: Ken-oh, Reina of the Twin Blades, Thouzer the Holy Emperor.
* OhCrap: Several.
** The Demon King Goran when he finds out he is fighting a practitioner of Hokuto Shinken.
** Gion himself when he finds out that Raoh and Kokuoh-Go are on their way to his fortress.
* RapeIsASpecialKindOfEvil:
** In the first episode, the Jirai Gang fly a dress which belonged to a young girl like a flag from their vehicle, with very clear implications that this occurred. They don't last long following their encounter with Raoh.
** In a very [[DownplayedTrope downplayed]] example, Juda (serial rapist extraordinaire) is made into the shows ButtMonkey, constantly getting belittled and having the crap kicked out of him.
* RapidFireFisticuffs: A requirement for anyone who practices Hokuto Shinken.
* ScrewThisImOuttaHere: Club gets the hell out of Dodge before Ryuga shows him his spine.
* KickThemWhileTheyAreDown: Kokuoh-Go's primary form of attack. Granted that he is the size of a freakin' elephant.
* YouKillItYouBoughtIt: Nice castle, Demon King. I think I'll take it.
* YouWillBeSpared: Raoh not only spares Gion (as it was through his attempts to kill him that he was able to meet and recruit [[CoolHorse Kokuoh-Go]]), but makes him a general in his army.
