Warriors Orochi is a Massive Multiplayer Crossover made by KOEI, encompassing the historical Warriors series (Dynasty and Samurai), with the addition of several original mystical characters here and there.The story is about a powerful demonic Blood Knight with a big scythe named Orochi, the Serpent King (instead of a eight-headed snake monster), committing some sort of sin, thus he is sentenced to eternal damnation. Meanwhile, the fox demoness from the Fengshen Yanyi epic novel, Da Ji, somehow sympathized with him. Acknowledging the chaos that he could bring to the world, she sets him free For the Evulz. United together and true to his Blood Knight nature, Orochi starts seeking out Worthy Opponents. Solution? Merge the eras of the Three Kingdoms and Sengoku Period together and go challenge their warriors. One by one, they begin to fall to Orochi's might. Unfortunately, his actions made the gods aware of his activities and they came to put a stop to them, but Orochi gathered some of the officers that he defeated to serve him and kicked their asses.However, the other warriors did not sit idly by under oppression. They banded together and eventually kicked Orochi's scaly ass right back to hell. Da Ji escaped and summoned another relic from the past: Taira no Kiyomori from the Kamakura era, whom she converted into a follower of Orochi. Then Kiyomori went back to the ancient lands and freed Sun Wukong from Buddha's imprisonment thereby gaining his services. At the same time, Da Ji convinced the mystical queen of Japan, Himiko, to befriend her. Together, they set their sights on reviving Orochi. The gods (mostly Chinese), however, decided to take more active stances, and thus the mystic Taigong Wang (who happens to be Da Ji's nemesis from the Fengshen Yanyi epic), as well as the gods Fu Xi and Nuwa (who have undergone a serious case of redesign since Dynasty Warriors 3) split up and aid the mortal warriors from the Three Kingdoms and Sengoku era. Other than them, another figure, Kiyomori's legendary rival Minamoto no Yoshitsune, also arrives in the twisted era to hunt down his worst enemy...The game features a tag team system, which allows the player to take three characters and have them fight on the battlefield. The characters are divided into three different types: Power, Speed and Technique, which affect their fighting styles so far.There is also a Super Robot Wars Original Generation style expansion called Warriors Orochi Z, for the Sony Playstation 3, which features more extra costumes, additional scenarios as well as new characters, including a Gender Flipped Sanzang from the Journey to the West, and Yoshitsune's buddy Benkei. Alas, also in the vein of minor expansion packs, Warriors Orochi Z has been deemed unworthy of being brought over the pond. A crumb of comfort, though, is that all of the new goodies made for Warriors Orochi Z has been brought over to the PSP port of Warriors Orochi 2.Musou Orochi 2/Warriors Orochi 3 was released on December 2011. It combines the cast of Dynasty Warriors 7 with Samurai Warriors 3, as well as a slew new characters from various folk tales/mythologies: Kaguya the Moon Princess from Tale of the Bamboo Cutter, Shuten Douji the lord of all oni, Nezha the Heavenly General and friend of Sun Wukong, and finally, Susano'o, the original slayer of Orochi. Aside of that, Koei included 'Collaboration Characters' from their other franchises, including, Ryu Hayabusa and Ayane of Ninja Gaiden and Dead or Alive, Jeanne D'Arc of Bladestorm The Hundred Years War, Achilles of Warriors Legends Of Troy and Nemea of Zill O'll. The English version was released March 2012. However there is no dubbing, only Japanese with English subtitles.A PSP version was also released and titled Musou Orochi 2 Special on July 19, 2012, it adds Abe no Seimei a legendary onmyōji as well as Rachel from Ninja Gaiden. This version also suffers another case of No Export for You due to the PSP being dead outside of Japan. It is also a launch title for Wii U as Warriors Orochi 3 Hyper, which is basically like the PSP version, but with a new mode called 'Duel Mode', a fusion between VS fighting and a card battle, as well as the addition of yet another mystical character, Shennong, and Momiji, again, from Ninja Gaiden.The storyline is that the world did achieve relative peace after the events of WO2/Maou Sairin, but years later, Da Ji returns with Kiyomori AND a gigantic new beast known as the Hydra, an 8-headed serpent like how Orochi was in myth. What resulted is a tragic Curb-Stomp Battle that leaves everyone from DW/SW and the exclusives of WO dead. The only survivors are Ma Chao, Sima Zhao and Takenaka Hanbei, and they are visited by Kaguya who sends them to the past and gives them a chance to prevent the total onslaught they just received....And even after all those supposed 'Grand Finale', it didn't stop Koei from churning out yet another iteration, in the same vein of Maou Sairin, called Warriors Orochi 3 Ultimate. All that's known so far is that it has a new story, was released in Japan for PS3 and PS Vita in 2013 (no word yet on a US release), and aside from adding Abe no Seimei, Rachel, Shennong and Momiji in this installment, they're also putting in Xu Shu, who made his debut in DW7 Empires, the main star of Dead or Alive, Kasumi, who made her Ninja Gaiden debut in Ninja Gaiden 3: Razor's Edge, and an Atelier rep, in the form of Sterk from Atelier Rorona. along with several new mystical characters: Tamamo-no-Mae, Yinglong, Youko/Kyubi no Kitsune, and Hundun. An earlier incarnation of Nezha, which depicts him as he appears prior to the events of Warriors Orochi 3, will also appear. Further scans also show another guest character that's not from Koei-Tecmo, but from Bandai Namco...The Soul Series' Sophitia Alexandra.
Most of the tropes provided in the previous games also follow here. Ones that stand out are:
A Day in the Limelight - Most of the big names from Dynasty Warriors and Samurai Warriors are dead, brainwashed or unavailable for the early parts of Warriors Orochi 3, so the game gets to focus much more on the lesser-known guys first.
Ah, forget those weapons! The premise of the game itself is an Anachronism Stew: The Three Kingdoms era is roughly between 220-280 AD, and the Samurai Warriors period is between the 16-17th centuries, being more than ONE MILLENNIUM apart.
Taken up to next level in WO3 which includes Nezha, designed like a Ridiculously Human Robot with Tron Lines. Plus, there's the Hundred Years War, Trojan War and Modern Day to be pulled to the stew.
Not only that but some locations fall into this, such as a modern day Anegawa. Justified due to the Hydra's mere existance twisting time and space.
Kunoichi: Look out, boys! Here comes a real foxy lady, Orochi's right-hand gal, Da Ji! She's cruel, she's crafty, and she left the house this morning without any pants!
Ascended Extra: Hundun is basically the Chinese name of Hammerjaw, a Dodomeki-like Orochi general who is aligning himself with Yuan Shao. In Ultimate, however, he becomes a terrifying demon possibly being an even Bigger Bad than Orochi.
Awesome, but Impractical : Many moves can become this, but the most notable example are, surprisingly Orochi himself. Almost all of his moves are non-elemental, deals small damage, has awkward coverage, and is unsafe in general. The only thing that saves makes him the Purposefully Overpowered character that he is intended to be are his C1-1.
Awesome But Practical : Triple Attack and True Triple Attack in 3. It is as effective as it is awesome, freezing any enemy you hit and pile them all up at the finish for a group kill. Also awards you with more gems if you manage to get a high combo, making it both necessary and entertaining to use.
Badass Boast - There are several quotes that are quite notable. In one dream stage, Shibata Katsuie calls out to the Orochi forces with "Pathetic gutter trash. You couldn't outfight my corpse!"
The final battle in the Shu story of 2 has one from Sima Yi when you finally get to him. If you get to him as Zhuge Liang, though...
Big Damn Heroes: WO3 invokes this as part of its time-travelling story, as the heroes travel through time to change events so that their allies would survive battles they would otherwise perish in.
Bishonen Line - Orochi. You would think he looks like that eight-headed snake monster, wouldn't you? And let us not speak of Orochi X...
Another strange example is with the Hydra itself which, as a manifestation of Orochi's raw power, turn's itself into 8 Orochi clones once defeated, and then after that the previously mentioned Orochi X.
Blood Knight - Several characters have no purpose except to pursue as much bloodshed as possible, not the least is the big bad, Orochi. Achilles is another example; he's just not happy unless he's always putting his Super Toughness to the test by fighting as many guys as possible.
Bragging Rights Reward: If you do absolutely everything in Orochi 2, you can unlock Orochi X, the One-Winged Angel version of the original. However, by the time this is done, it's time to put down the game...
In the first game, the fourth weapons are this. They and the fusion weapon system are essentially meaningless when most of the game is getting off your attacks before you get hit, and in the Chaos difficulty, a regular Mook can kill even a Level 99 character in 5-6 hits.
Also in the first game, getting all your abilities maxed out is this. By the time you have achieved this, you've already unlocked all of the characters, and by that time, these maxed out abilities are unnecessary when they could have helped in trying to advance through the game earlier.
Continuity Nod - At Komaki-Nagakute in the second game, Cao Cao tells Pang Tong - who caused a massive fire attack on Orochi's forces - that he was thankful that the hooded strategist was an ally, otherwise it'd be Cao Cao, and not Orochi, who would be "drowning in a sea of flame". Pang Tong was one of the Shu officers responsible for his historic defeat at Chi Bi.
Culture Clash - Ancient Chinese warriors and Sengoku Era Japanese daimyo fighting together or against one another. Then there's the use of firearms! And then there's the Frenchwoman and the Greek warrior...
Disapproving Look: Yukimura gives one to Yuan Shao for thinking his enemies are ghosts.
Darker and Edgier - Although Dynasty Warriors 7 and Samurai Warriors 3 are already somewhat grimmer than their predecessors, the crossover turns things up a notch by setting the game in Just Before the End, letting named characters getting brainwashed into servitude or dying on-screen, something that players won't know they can avert until quite a while into the game, and introducing an Eldritch Abomination as the new Big Bad which the protagonists and co. struggle to fight off just to survive throughout most of the game.
Decapitated Army: Losing the commander means an instant defeat, both for you and your enemies. That feature makes the commanders' Leeroy Jenkins tendencies quite annoying.
Did We Just Have Tea with Cthulhu? - A major part of Bonds in the third game, where you can invite anyone to a pleasant banquet (from the Tea House, no less!), even if the other party is the Omnicidal Maniac responsible for creating the world the characters currently reside in or his dragon. Amusingly enough, you can do this on a more literal level by inviting them to a "Tea Party", which is the initial way to rise affinity in the game.
Third game's DLC has TWO scenarios where Dong Zhuo attempts kidnapping ladies of the game for his paradise of beautiful women: First, Dong Zhuo's Ambition where he kidnaps Aya, Kai, Joan of Arc, Cai Wenji, Wang Yuanji, Kaguya and Ayane. And eventually thwarted by a team of Magoichi, Hayabusa and Taigong Wang. Second, Zhong Hui's Pride, which is the same but Dong Zhuo had Zhong Hui to do the dirty job of kidnapping Nuwa, Ina, Da Ji (even if they're allies or sorts), Wang Yuanji (again), Diaochan, Zhurong and Gracia (the last two escaped), until Zhong Hui has had enough and storm off, driving off would-be rescuers, Dong Zhuo, as well as the ones Zhurong and Gracia called for help (Meng Huo, Mitsuhide, Motochika). There's also another scenario where you play as Dong Zhuo's forces fighting the resistance forces... and showing that you've captured Sun Shangxiang, Zhenji AND Ina to immobilize Sun Jian, Cao Pi and Tadakatsu. Just be careful of Hanzo and Zhou Tai trying to rescue them.
Downer Beginning - In the first stage of the third game, we are thrown into a battle where it's just Ma Chao, Sima Zhao and Takenaka Hanbei (and some generics) against the Hydra. None of the siege weapons do more than Scratch Damage against it (and it just regenerates said scratch damage), and the weapons are destroyed in just a few hits, with each destroyed weapon drastically lowering your allies' morale. On top of that, they're all being pursued by the massive Demon Army under Kiyomori; you will lose your generic allies no matter what you do (generic allies who happen to have really depressing death quotes specifically for this stage only) and your only escape route is promptly sealed off by Da Ji. It takes a practically-literal Deus ex Machina to bail the characters out of this situation, lest Warriors Orochi 3 become the shortest, most depressing full-priced game ever.
Empty Shell - The Hydra is revealed to be partially this, as it is a manifestation of Orochi's raw power without his consciousness. This is even more apparent when the Hydra heads transform into clones of Orochi upon defeat.
Excuse Plot - So. We have a powerful demon who wants to fight the best that East Asia has to offer right. So what does he do? Take Three Kingdoms Era China and Sengoku Era Japan, then ram them together.
Warriors Orochi 3 gives a somewhat more fleshed-out plot with emphasis on the relationships of the characters.
Expy - Himiko has only appeared in one other Koei game outside of Orochi, Kessen II, (an EXTREMELY loose, fantasy-version of Romance of the Three Kingdoms that is not in canon with Dynasty Warriors) and there, too, she was a spoiled, petulant brat with supreme magical powers. This Himiko isn't the same one, but she's gone from being clingy over conquerer Cao Cao to being clingy over Da Ji the devil lady.
Extreme Doormat - Diaochan is like this towards Lu Bu in the second game. However, she will rebel against him if she feels that he's straying far from his own ideals.
Face Nod Action: In the opening of the third game, Sima Zhao, Sima Shi, and Wang Yuanji do this. A moment later, Yukimura Sanada and Zhao Yun do it.
Fake Difficulty - Chaos difficulty is no different from Hard, for the most part. Enemies have the same HP (more or less), AI is the same, they deal the same amount of damage... the only difference is that their attacks completely ignore defense. A regular Mook can now kill you in four hits. Did we mention you will often be surrounded by a few hundred mooks, with a few officers in the middle to spice things up? Enjoy.
Fanservice - This is pretty much the singular purpose of this game. Not that the fans mind for the most part...
Many of the females characters have cute, fetishy outfits, most blatantly Da Ji and Nuwa.
Fighter, Mage, Thief: Characters are classified by three categories: Power (who hit harder and are Immune to Flinching), Technique (who can do sidesteps while blocking and can perform in Critical Hits on airborne enemies) and Speed (who can Air Dash as well as jump cancel their attacks). The third game adds "Wonder" (who can cancel any of their attacks with an unique attack that breaks guards and perform Critical Hits like Technique characters).
Gotta Catch 'Em All - This is how Warriors Orochi 3 is set up. Instead of having stories for different "sides," all player-controlled characters are on one side, and your mission is to travel backwards to earlier events and collect as many warriors as you can before the big Hydra showdown. Every single battle you complete will give you at minimum one new warrior, possible three or five! To get the Golden Ending you need to get everyone you possibly can. This trope is also one of the reasons Warriors Orochi 3 is so fun to play; Gotta Catch 'Em All is an inherently addicting trope.
Guest Fighter: Since 3, they started introducing characters outside the both Samurai/Dynasty Warriors series or original creations, starting with Joan of Arc, Achilles and Nemea... and due to the merging with Tecmo, they're able to put in Ryu Hayabusa and Ayane. As they gave out more additions, they started giving out Rachel, Momiji and eventually as of Ultimate, they also brought in Kasumi, followed by Sterkenburg Cranach. All of them are Koei-Tecmo properties... when suddenly, they introduced Sophitia Alexandra, who is from a Bandai Namco property, that's some high level of 'guest'.
Grapple Move: Characters from Samurai Warriors (starting from with SW 2) and Dynasty Warriors (starting with DW 5) retain whatever grab move they had in their respective game, like Lu Bu's choke slam move from 5 and Wang Yi's ground "aerial slash" musou and aerial "ground pin" from 7.
Hailfire Peaks: The landscape is often a mash of multiple different ones with Hydra-shaped lava flows between them. In levels where we meet Joan of Arc or Ayane, we see bits of Medieval France and a modern day beach resort also crammed into the levels alongside Japanese castles and such.
Hard Mode Perks: Like in Dynasty Warriors. This also includes getting any of the rare equipable items in the third game, which require you to get 1000, 1500 or 2000 kills in a level on Hard or Chaos while also having at least one character out of 5 or so in your team.
The Dragon, Kiyomori, lampshades this. When a random henchman tells him that Lu Bu has betrayed them, Kiyomori replies, "Betrayal? No, that man... is being true to himself."
Lu Bu's got a tendency to change sides in the hopes of finding a fight that will actually give him a good workout. His swap quote is even "Challenge me!", driving this point home. So yeah, not so much a Heel-Face Turn as it is a Blood Knight pulling off an Enemy Mine in the hopes that Orochi and Kiyomori will present the fight he wants (since Wu doesn't seem to be making the cut).
In the third game however, if Diaochan comes to his side during one of Lu Bu's fights with Nezha, he'll automatically defect to the Resistance at her urging.
Considering that Shuten Doji is the conscience of Orochi, which essentially means that he IS Orochi, one might argue that Orochi himself makes a face turn after joining the Resistence against the Hydra, which is Orochi's raw power without his mind.
Also in the third game, Keiji and Masamune, after two titles being unrepentant servants of Orochi, eventually defect for good after one Hydra head is down and they realize that this is not the Orochi they used to trust. This is before the reveal about Shuten Doji (See above)
Subverted with Dong Zhuo, though. He did join the resistance, but that's because Zhuge Liang forces him to so he doesn't bother the resistance with his petty ambitions and dreams.
Once the Normal Ending is unlocked in the third game, you'll find Gyuki and Dodomeki in the camp, stating that they were press-ganged by the Resistance to atone for their crimes. They're actually OK with this and even get a DLC mission about proving themselves.
Hero Antagonist: Ranmaru Mori at first and Xing Cai in the Wu campaign in Warriors Orochi 1.
Historical Beauty Update - Wasn't Taigong Wang supposed to be an old man? (Then again, those times are Shrouded in Myth and Taigong Wang's name is actually a reference to how the future King of Zhou's father had told him to keep an eye out for a good strategist, so his name means "the one hoped for by my honored father".)
Hitler's Time Travel Exemption Act - Moon Princess Kaguya shows up in WO3 to help the last remaining three heroes save everyone who was killed by the Hydra by traveling back in time. One restriction, though: she can't time-travel to before the Hydra emerged because it's created a rend in space/time, so no going back to before its birth and blowing it up then. (Even later, when you find someone who CAN time-travel further in the past, it turns out to not be so simple.)
Slightly averted in Taigong Wang's case, since he's a freaking god and can use whatever he wants to massacre an army of cannon blade fodder. Arguably applies to Himiko's and Da Ji's weapons as well.
Also, in Taigong Wang's case, his weapon is a reference to the myth of him being a peerless fisherman; one who could get fish with naught but a rod. It's arguably his most defining accessory/weapon.
How many other games let you legitimately say the final boss died because you smacked him in the face with your balls?
Of course, you kinda of have to mention the characters from the two base games. Easy ones to point out are a flute, an ass kicking flute, feather fans surprisingly good at smacking people, and then you have a spear that houses a MASSIVE LASER CANNON in it's slightly engorged head.
It's Personal - When you first encounter Lu Bu in 3, he is singularly obsessed with killing Nezha. The reason for this? Not because Nezha beat him, though he did, but because he then proceeded to casually kill Diaochan in front of Lu Bu. Lu Bu has been out for his blood since before the Hydra even appeared.
Kitsune: Da Ji is called a fox many times and her feet doesn't hide this fact any little. And then there is Tamamo-no-Mae. What is next? Inari is going to appear and have his own focus in a new Warriors Orochi where he forces Da Ji and Tamamo-no-Mae to help him seal Orochi too?!
Large Ham - Too many to list. It would probably be easier to try to list those who were actually playing their role straight.
Though a shining example of this trope is Zhang Jiao and his 'Wrrrrrrath of the HEAVENS!!'
The Last Dance - Meta example. KOEI actually didn't want to continue the series, but the fanbase demanded. So they decided to put everything as the ultimate Grand Finale of the Orochi series. The results thus far has been positive... so positive that they had to churn out another expansion that makes the True Ending non-canon and opens up possibilities to continue the story. And more Guest Characters.
Lethal Joke Character - Gracia, again. Her attack power and range are both horrible, below decent at best, and her cavalry skill is easily shut down due to the absence of the no-dismount-when-hit horse. Then you discover that single technique and proceed to kill the enemy commander from full health in under a second. Oh ho, even Orochi's trembling at the sight of her.
You'll LOATHE having to fight against Himiko. You'll be massacring entire armies and shiver in fear at that little girl when she activates her Musou attack and wrecks your crap.
Lettered Sequel: Only exist in the japanese version though, the second game is originally titled Warriors Orochi Z, which is released in the US as Warriors Orochi 2.
Lethal Joke Item: In the third game, the Big Star Weapons tend to start off with very low attack power and occasionally have very silly-looking skins. However, after a bit of grinding they become Infinity Plus One Swords.
Lighter and Softer - Koei sure not only wanted these characters battle each other, they have made them have senses of humor talking to each other. The Dream Stages on WO 2 furthens this up a bit more, since they're no doubt even more lighthearted than usual.
Inverted for Orochi's story on WO 2, where, instead, it's Darker and Edgier, most notably on the final battle against Wei.
Too bad the Orochi campaign is a prequel to the first game, instead of being set during the events of everyone else's campaigns in the second game.
The third game doesn't even have different sides, at least not different sides not controlled by the player. Instead you're collecting as many warriors as you can to fight off the Hydra, and in some demons' cases this means capturing them and impressing them into your service. Some of the guys you collect are pretty evil, though, including Da Ji.
Numerical Hard - Although enemies already do receive substantial stat boost at the maximum difficulty in the two base games, this crossover turns things up several notches by increasing the stat boost to the degree that even a maxed-out character will die from a dozen blows from the lowest mook. Granted, the player can boost up their damage as well with the tons of weapon attributes they can imbue in this game.
Old Save Bonus - For the PSP versions. Allows characters in the sequel to gain their first ability immediately.
Out of Focus: In the third game, if you go a while without using character, you can listen to them talk about how they're bored or angry at being kept from the battlefield. (Of course, with Loads and Loads of Characters, there's always somebody you haven't used in a while.)
Relationship Values: A major part of the third game. Each character has a group of other characters with whom they share a bond to. Increasing it via fighting together or holding feasts will lead to unlocking various passive bonuses and even special stages to unlock new characters.
Revenge Before Reason: Wang Yi appears to be controlled by Orochi, but when she broke free of it, she's still vengeful on Ma Chao and attempts to kill him until Noh and Oichi stops her.
Set Right What Once Went Wrong: The entire storyline of the third game. Also, most stages may involve a character dying outside of your control, after which a few characters will try to help them out in a stage that will result in a Redux version of the previous stage where the character can end up surviving and join the Resistance.
Masamune Date and Sima Yi (who are already the Smug Snakes of their games) tend to share stages with each other. The third game has Zhong Hui, who initially serves Dong Zhuo for his own reasons before trying to strike out for himself.
Stripperiffic - To the point that EVERY NEW FEMALE, except Himiko, has this. God, for a monk priestess, Sanzang sure doesn't dress up so purely...
Averted with Kaguya, who was designed to reflect Heian era sensibilities for the most part - the only made her skirt shorter so she could "move" more easily, but it still has 12 layers!
Surrounded by Idiots - Dong Zhuo is hilariously blustery when his minions lose a stronghold. "What were you doing! Drag your sorry carcass back up there and reclaim that mountain!"
Sakon: "So interesting I feel like tearing out my hair."
Talking to Himself - Happens constantly with some of the characters who both share the same voice actor and have a bond with one another. Exemplified in the Japanese dub by Daqiao and Xiaoqiao, Jia Xu and Motonari Mori (who got a scenario where they interact a lot), Nene and Ayane, Motochika Chosokabe and Sima Shi, Nuwa and Kaguya, etc.
Theme Music Power-Up - With both Lu Bu AND Honda Tadakatsu in the crossover, naturally they would carry over their theme tunes (The former has a remix specifically for this game). It wouldn't be until Musou Orochi Z, when Orochi himself would finally have his own. Played with in the new DLC for Warriors Orochi 3 "Fight for a Theme Song" this is where Keiji Maeda wants a theme song for his own. note this is the only DLC scenario where you CANNOT change the BGM. (At least in the Japanese edition) In the third game, Ryu, Ayane, Achilles and Susano'o's introductions result in their themes replacing the stage music.
The Rival - Yoshitsune gets this, naturally, with Kiyomori. More surprisingly, he gets another... in Lu Bu. The latter however, isn't a clear cut rivalry in the traditional sense. The third game adds Shuten Doji to a minor extent.
Also, just about every pair of rivals from their respective games, still retain that sense regardless of what side they're on.
The Strategist - from the second game onwards Taigong Wang takes it upon himself to plan most of the battle against Orochi. Hanbei takes this role in the third game.
The Vamp - Zhenji, No, and Da Ji. The three of them can even perform a special triple attack together in the second game.
Title Drop: Joan of Arc gives us "A storm of blades shall part the enemies before us" if you kill an officer in her presence (but she's not in your party).
Took a Level in Badass - For the first time ever, Xiahou Yuan is both competent and has a few significant story moments in the second game. Dong Zhuo has agruably also received this treatment, becoming an actually competent (albeit still whiny and pampered at times) villain who is also a vital figure in Orochi's army.
Back in Bladestorm, Jeanne was a mere Hero Unit. Now, she picks up a spear and has her chance to rack up multitudes of KOs all by herself.
Too Long; Didn't Dub - Warriors Orochi 3 is the first Warriors game released internationally without any English dubbings, and with the ample amount of new vocals added in by the upcoming expansion, chances are it's probably stuck this way for good...
Also, a number of the Dream Stages play out like this. The Three Kingdoms leaders vs. the Unifiers of Japan, the legends of the Heike vs. the Daimyo of the Sengoku, the gods vs. the best of the mortals, Honda Tadakatsu, Lu Bu, Keiji Maeda vs. Orochi... the list goes on!
Underboobs: Da Ji has an outfit in Musou Orochi Z and the third game that shows this off. Diao Chan also has her Dynasty Warriors 6 outfit.
Unexpected Gameplay Change: The third game gets this in the form of the Yashio'ori, which you have to man and use to defeat the Hydra in the same fashion of using a ballista. While this is foreshadowed somewhat in the intro level, after spending hours in the typical Warriors tradition grinding your characters up to scale, it is quite surprising to see the gameplay jumping from the usual hack-n-slash to a Rail Shooter-esque "attack the weakpoint" level.
Unholy Matrimony: WO3 has Da Ji and Achilles with serious affections for one another, mostly a case of In Love with Your Carnage. One camp conversation has Achilles sweet-talking Da Ji by saying that a cruel and beautiful woman like her needs to be surrounded by the screams of combat.
Wake-Up Call Boss: In WO3, Yuan Shao and Himiko are this, depending on the route you take. Yuan Shao is a competent fighter, having quick, strong attacks, strong bodyguards, as well as having an unblockable Musou Attack which deals great damage, hits twice and has long range. It's a OHKO/2HKO at this point for all your characters. For the other route, there's Himiko, who has the strongest Musou Attack in the game, however it can be blocked (If you are fast enough to react). Unless your character is Lu Bu or Ryu Hayabusa, you are pretty much dead if you get hit by it.
We Cannot Go On Without You: If the character currently controlled dies, it's Game Over, even if the other two characters are still at full health.
Wham Episode - WO3 starts off with almost everyone dying, with the story being to go back to avert this incident.
Near the end of Chapter 3 we have the reveal That Da Ji had been hiding the body of Orochi X, which turns into the Hydra, which is revealed to be a manifesation of Orochi's raw power. Oh, and Shuten Doji is revealed to be a manifestation of Orochi's conciousness.
What If? - This is the basis for many of the Dream Stages, set scenarios that allow for cool, strange, and outright peculiar combinations, and also give some depth to some of the characters.
The Worf Effect: Nezha manages to inflict this upon Lu Bu several times in the third game.
Nezha himself gets this from the player. Even after you've beaten him a couple of times he'll still talk about how "impossible" it is for a human to beat him.
In the third game, this is the reason that certain characters end up dying in the original timeline, having sustained a grievous wound in a previous battle. Thanks to Kaguya's time powers, the characters can go back and provide some much-needed backup so that the character will survive the events and join the Resistance.
