An artwork featuring the main heroes of the franchise, before 2004's Suikoden IV.
Suikoden is a series of games (released on various consoles, starting with the original Playstation) that are loosely based on a classical Chinese novel, The Water Margin (or Outlaws of the Marsh and All Men are Brothers). These games are notable in that they all take place in the same world, although at different periods and locations throughout its history. Some games are chronologically close enough to each other that they feature many of the same characters, although the main hero (or heroes) of the game are always new characters. They tend, as a rule, to be Kid Heroes, but not always...Certain major themes which run throughout the series are:
A hero who finds himself running afoul of an evil force, be it a foreign empire, a dark conspiracy, or his own government turning against him. Said hero is usually then forced to go into exile.
The main hero having to set up an army by locating and collecting 108 special people (known as "the Stars of Destiny") who are scattered throughout the world. Some of the "Stars of Destiny" are fighters who accompany the hero into random and plot-based war battles, while others are support characters, who can aid with healing, navigation, etc.
Sometime during the course of the hero's adventures, he acquires a Home Base in which his highly specialized army lives and works. This Home Base starts out small but grows and develops throughout the course of the game.
The game has a plot which centers heavily on politics, overcoming corruption through strategy and/or revolution, and dealing with the betrayal of a close friend or ally.
The plot of the game is heavily influenced by one or more of the True Runes, 27 at least semi-sentient elemental symbols which contain the power of the universe and which grant their owners special abilities (immortality being chief among them). The ending battle of the game is usually fought against a villain carrying a True Rune themselves, their goals often intertwined with said True Rune's nature in some way.
Combat occurs in the game via Random Encounters, strategic war campaigns against enemy armies and one-on-one duels, each with its own graphics and battle system.Suikoden III is a notable deviation from the other games, in that it is about a trio of heroes, each of whom has an equal chance of possessing the game's main MacGuffin, the True Fire Rune. At one point in the game, the player gets to choose who acquires the Rune, a choice which will affect the plot for the rest of the game.The Suikoden universe is encompassed by 5 main console games, Suikoden, Suikoden II, Suikoden III, Suikoden IV, Suikoden V and a group of spinoffs: a Strategy RPG game Suikoden Tactics (Rhapsodia in Japan); two canon Visual Novel games called Genso Suikogaiden 1 and 2, featuring the adventures of Nash Latkje which provide background to Suikoden 2 and foreshadowing for 3; a GBA adaptation of the card game shoehorned into a retelling of Suikoden II's plot; and a Nintendo DS spin-off called Suikoden Tierkreis, which is set in an alternate universe unconnected to the main Suikoden world, none of which save Tierkreis have seen an English language release. There's also a slot machine game released in 2010, which saw the fans basically thinking "so this is how it ends, huh?" And then a new PSP project is announced.Among fans, Suikoden II is usually considered to be the strongest of the series (too bad it's also the one you're least likely to find, and the most expensive if you do find it), while IV is widely seen as the weakest. While not as graphically flashy as other video game series like Final Fantasy, this series has a lot to offer for gamers who like long and involved plots filled with intrigue and interesting characters.
Effectively should you choose to take it: You and your True Companions) just became Destiny'sChew Toy. You get powerful magics (which might be enough to fulfill your destiny) and stop aging (but Who Wants to Live Forever??) ...mind you...there are some fantastically cruel drawbacks (all your closest friends dying, loss of sanity, etc. etc..)
The original gives you a possible Ho Yay between the Hero and Gremio .
Millay toward the hero in Suikoden IV
Lyon with the Prince in V; also, Lelei and Lucretia for the Les Yay version
Cecile to Thomas in the 3rd game.
Boisterous Bruiser: There's one for almost all the games - best examples include: Viktor, Ace, Lino En Kuldes, and Boz Wilde
Bunny-Ears Lawyer: The Knights of Maximillian. Starting with expys of Don Quixote and Sancho Panza, all members of the order are quirky, cartoonishly over-the-top fantasy wandering knights with extremely idealistic views that clash pretty hard with the more realistic tone of the setting, leading to them being predictably treated as silly weirdos. They are also extremely competent and skilled warriors, with a good eye for seeing right from wrong and very hard to dupe. Turns out that the reason members of such an inconvenient, disorganized and orphaned group can survive on their own just to randomly smite non-specific evil is that they are incredibly good at it.
But Thou Must: Only rarely do any of the speech choices a player is given have any effect the flow of the plot. Suikoden V has a few notable exceptions, as does one or two parts of II.
Ironically however, he never got around to the murdering his father and taking the throne part of this trope before the heroes did away with him. Then Jowy fills in that blank by marrying the princess, killing the king, and taking over the country himself in a misguided attempt to stop the war.
But he does manage to get around to murdering his father. As part of an elaborate plot, during Jowy and Jillia's wedding ceremony, Luca's father the king and Jowy drink from a ceremonial wine goblet. Knowing this, Luca has Jowy build up an immunity to a poison he places in the wine; the king isn't similarly immune, and ends up dying. Luca then becoms King, if only for a brief period.
Actually Jowy's blood, not the wine, was poisoned. Luca had to taste the wine before his father would touch it, so the only way to poison the king is to poison Jowy's blood, which is put fresh into the cup just before the king drinks it.
Captain Ersatz: Lucretia Merces may be just about as close to a female Zhuge Liang you're going to get, Shu from II is a more straight example however. Additionally, throughout the series, many characters are expies of characters from earlier games; this is possibly justified by the fact that your characters are represented by named 'stars', and frequently characters who join under the name of a particular star in different games share several characteristics — when it isn't the exact same character, of course. Richmond from II is also an obvious ersatz of Columbo and Stallion just might be a subtle one to Sonic the Hedgehog, since he has spiky blue hair and is considered the fastest creature on land. Maximilian & Sancho from Suikoden I are pretty much Don Quixote and Sancho Panza.
Celibate Hero: Flik, after the death of his lover Odessa Silverberg.
Sialeeds to Frey in Suikoden V even though they're aunt and nephew.
Cute Mute: Pilika, a little girl in Suikoden II whose guardianship jumps from Joey, to Nanami and the Hero, to Joey again. She didn't start out mute, though, and there was nothing cute about how she became so.
Defeat Means Friendship: Especially prominent in the first game, though it crops up in some of the others, too. Almost every game has one or two enemy generals who join you after you beat them militarily, and several other characters who will only join after a one-on-one duel.
Dirty Coward: Snowe from Suikoden 4 who among other things, abandons his subordinates in a battle that he instigated because he slightly injured his arm! Euram Barows in V, though he does get better.
The Ditz: Viki, who keeps teleporting through time and space merely by sneezing.
Dojikko: Viki is so clumsy, she sneezes herself through time and space. It's a running gag that at the victory banquet at the end of each game, she sneezes herself straight into the middle of the next one, despite the games being centuries apart, and not in chronological order.)
It's implied in the third game that she's a historian from the future doing this on purpose to document historical events first hand.
Duel Boss: Several of them at regular intervals for each entry in the series.
Earn Your Happy Ending: Carried out both in the story and in the gameplay. The characters will suffer through all the tragedies and losses of war and then some, but if you can recruit all 108 Stars of Destiny, the ending makes it all worthwhile.
Empathic Weapon: Although not weapons in the traditional sence, all 27 True Runes are sentient for the most part, one of them takes the form of the Zodiac/Star Dragon Sword.
Interestingly, the sword is an absolute Jerkass to everyone. Even it's 'preferred' wielders.
Mr. Fanservice: Flik. It's hard to tell in the original, what with the low quality graphics, but he DOES get one character to join the group by drinking tea with her all night (at her request). It's far more prevailent in Suikoden 2, where women regularly hit on him, and is constantly being pestered by Nina. Most of the heroes are this as well, with the possible exception of Lazlo.
Lazlo might even qualify too, since he technically has 3 girls (Rita, Rene, and Noah) that are interested in him instead of the usual 1 that the rest of the characters get. There's just not that many scenes where you see it. Just an optional bath scene where they discuss getting him a gift (Rene even suggests "a girlfriend"), plus the three of them give him a wooden amulet as a good-luck charm on the night before the final battle, acting like schoolgirls the entire time (giggling and everything).
Four if you count Millay, his self-proclaimed bodyguard.
The heroes' tendency to be this is humorously lampshaded in the unlockable sidequest in 2. During Riou's conversation with Cleo, you can choose to hit on her, causing her to remark that "you're a lot like the Young Master in many ways."
Also, as noted above in Chick Magnet - any of those who can band together for the male variant of pretty girl/woman attack is effectively implied to be this.
The Evil Prince: Prince Luca Blight, though Bat Shit Insane Prince would be more appropriate.
Eyepatch of Power: Worn by Georg, arguably one of the most physically powerful human characters in the game series, and by Geddoe, the most bad-assed of the three main heroes in Suikoden III.
Fake Difficulty: Some of the easily lose-able one-on-one duels occur right after a long and involved tactical battle campaign, with no opportunity to save in between the two events — this seems to occur for no other reason than to heighten the player's tension.
Gambit Roullete: The fifth installment. The villain's plotting almost caused Arshtat to go insane and destroy the entire country. The father of one bad guy even calls him on his plotting, as he leaves too much to chance and doesn't do anything to stop unintended effects of his plotting.
Gameplay and Story Segregation: Having a teleporter who can instantly warp lone fighters, small groups, whole squads and even entire fleets at will would be immensely useful (And pretty game breaking) in any war, but in spite of this (Or rather, because of this), Viki's skills are completely ignored story-wise.
Gotta Catch 'Em All: Have fun recruiting all the Stars of Destiny! Sadly, Suikoden II forces you to choose between characters a couple of times, and you don't have enough Listening Crystals to recruit all the available monsters.
In Suikoden V, you have to choose between a mysterious, powerful mage who has nothing to do with the plot (and has her own secret dungeon quest, IIRC) and a non-fighting NPC who is instead very involved with the plot (and a defrostingJerk Ass).
Guide Dang It: Many of the "Stars of Destiny" you must recruit can only be acquired through obscure or non-intuitive means, or during very narrow windows of opportunity between certain Event Flags.
Guns Are Worthless: In a world of swords and magic, The Howling Voice Guild uses assault rifles. Lampshaded in Suikoden V when a member of the Guild explains that rifles are inferior to the bow-and-arrow because of the cost, difficulty to manufacture and reduced accuracy: however, they are useful as an intimidation tactic.
In game however the gun users are actually quite powerful. Both Cathari and Clive are some of the best damage dealers of the games they appear in and both rarely ever miss
Cathari also notes in that same scene that Guild members train extensively with their gun, until they know it better than they know themselves. This lets them understand the gun's drawbacks and adapt to cover them up. As Hazuki (the person who Cathari was explaining this to) comes to realize, Cathari talking about how guns were fundamentally weaker and less reliable ended up being pointless in Hazuki's eyes because she wanted to know how to best a gun-user. All she learned was that the Guild taught its members to work around the gun's weaknesses like any other weapon.
Technically, this extends to any member of the Howling Voice, including: Clive and Cathari
Hello, Insert Name Here: You name the main character in each game except 3, however their 'canon' names are given in supplementary material. Tir Mc Dohl in Suikoden 1. Riou in Suikoden 2. Lazlo in Suikoden 4 and Freyjadour Falenas in Suikoden 5. Most players abbreviate Freyjadour to Frey however.
Actually, those names aren't canon either - Konami has explicitly noted this; those names were provided by novelizations and manga (not unlike the name given to the unnamed main character of Persona3)
Tir and Riou became pretty canon through the Drama CD though.
Heroic BSOD: Poor Pilika watches as Luca Blight stabs Pohl to death right before her eyes, and after recovering from her BSOD she and her current guardians discover she's been rendered mute - for the rest of the game. Talk about Unlucky Childhood Friend...
Which, for the record, happens after her parents are brutally murdered while her home town is being completely razed. All things considered, it'll be a miracle if the poor girl isn't emotionally scarred for life.
Heroic Sacrifice: Quite a few actually, Odessa, Gremio, Teo, Ted, and Mathiu in Suikoden 1 alone.
At one point, Gremio sacrifices himself in order to save the hero and the rest of the party from General Oppenheimer's flesh-eating spores trap. Can also be considered a You Shall Not Pass as he prevents them from reaching the party. If you accomplish a certain unwritten goal, He gets better.
Also Odessa dies protecting a child, and begs the hero that her death remain a secret to keep the morale of the rebel army up.
There's potentially another Heroic Sacrifice after that when Teo and his Armoured Cavalry absolutely trounce the Liberation Army in battle. The hero, Mathiu, Pahn, and Cleo are fleeing when Teo catches up to them, along with his two lieutenants Alen and Grenseal. It looks hopeless until Pahn volunteers to try and hold Teo off while the hero and the rest of the group escapes. Pahn then duels Teo, and if he loses, he's executed as a traitor. However, this sacrifice can be avoided if you've trained Pahn up enough to the point where he can defeat Teo in the duel, who then allows Pahn to leave.
The secret to keeping Pahn alive is raise him to around level 40 or so, and during the duel with Teo, constantly defend and hope that Teo keeps using his special attack. If you keep defending, Teo's special attack will miss and Pahn will counterattack, so just keep this process up until Teo's health is gone.
Later on Ted does this to save the hero from Windy and to keep the hero's rune away from evil's hands.
And in the end Mathiu dies, after abandoning his desired life of pacifism and solitude to help the army save the kingdom.
The High Queen: Queen Arshtat of the Queendom of Falena fits this trope rather well, at least while at court, and especially while being influenced by the Sun Rune
Highly-Visible Ninja: Kasumi wears bright red and no pants in 1, and many of the others are just as bad. The only ninja that seems to avert this trope is Kage
Suikoden 2's Mondo and Sasuke, as well as 3's Watari and Ayame, mostly avert it as well (only "mostly" because Mondo is wearing white and Ayame bright purple, but they're at least dressed like ninjas, color aside). The ninjas of 4 and 5 are also debatable, as they seem to make an effort to dress more like normal people. In fact, 5's duo of Shigure and Sagiri are never outright called ninjas at all, many just think of them as such because they're former assassins for Nether Gate and they wield ninja weapons (Shigure uses a ninja-to while Sagiri throws kunai).
But considering that historical ninjas actually dress like normal people...
However, there are quite a few battles that are so poorly balanced you might think they're this, but aren't. Notable cases include most fights with Yuber in III (most of which mercifully don't affect the plot), and the first game's duel between Pahn and Teo (which is necessary to win for 100% Completion).
I Call It "Vera": It's a tradition for the men from Warriors' Village to name their weapon after what is most important to them, a tradition followed by Flik, Hix, and Mathias
Inexplicably Identical Individuals: Jeane, Viki and Leknaat show up in every Suikoden game, even though they take place across different time periods. Leknaat is immortal, Viki has been implied to be doing a bit of accidental Time Travel, and the developers have joked that Jeane has a family like the Nurse Joys from Pokémon. All three are the subject of huge epileptic trees, which the creators lovingly cultivate. Jeane in particular gains three different Word of God explanations a game, just for chuckles.
In Name Only: The first game was only tangentially related to The Water Margin in the first place, but every sequel has basically no relation to it beyond the concept of 108 heroes.
Jerk Ass: This is Luc's entire personality for the first two games. He's one of the most powerful characters in the setting, and at least until the third game, he uses that power exclusively to be petty and irritating.
Jerk with a Heart of Gold: Chris is a fairly decent person, but her personality can be kind of grating. She comes off as a bitch to practically everyone. She's a lot better in the manga adaptation, though.
Karma Houdini: Windy and to a lesser extent Barbarossa, among others. They were originally supposed to have died in the ending of Suikoden I, but their status was later Ret Conned to "Missing in action" in order to allow for the possibility of their return. Since their bodies are never shown, and the rune Windy bears remains missing, it's a believable retcon. The Muse-hired ruffians who raped Sara Blight and were therefore indirectly responsible for turning Luca into a villain may also fall under this trope, although Muse itself most assuredly does not.
Katanas Are Just Better: The setting is a fantasy world where Eastern and Western weapons and armor exist side by side. Except for Suikodens III and IV, the main heroes in all the games have a tendency to favor Asian style weapons — like bo staffs, tonfa and nunchaku — over Western style swords.
It should be noted however that most of the best fighters use western swords ie. Sheena in 2, Pesmerga in 1 and 2, Belcoot and Richard in 5.
Many of the heroes are healers or magic users over warriors, so these less lethal weapons suit their nature. The Hero in Suikoden II's rune is the Bright Shield, and his weapons are tonfa; both are meant for defense and protection.
And then there's Georg, who seems to like both, using a western sword in 2, but wielding a katana (actually an Iai blade, which may or may not be the same thing, depending on who you ask) in 5.
It's actually even more confusing than that. Georg's sword in 2 is a two-handed sword with a side-grip where the hand guard would normally be. (Like the Cypher sword from Strider) His sword in 5 is a short, double-edged sword that resembles a Chinese jian, but he uses it iai/battoujutsu style.
Apparently Yuber's King Crimson wasn't good enough in 2, and apparently he split it into two Katana-like swords in 3.
And quite often Shu, the protagonist's strategist in Suikoden 2, albeit because it was the most effective or only proper way to achieve a goal. Chucking little Pilika across a room full of crossbowmen ( who are on the brink of firing ) as a distraction to prevent them executing his army's leader, then abandoning her there, for instance.
To be fair on Shu, however, Pilika prefers being with Jowy rather than Riou's army and it was because of that Pilika regains her voice, so there's something beneficial that came out of it.
However, in Suikoden, your Kid Hero is aided by a cabinet of highly capable adult strategists. He's sometimes almost an inspiring figurehead, or simply their strongest warrior.
Potentially averted in III if you so choose.
Killed Off for Real: In tactical battles when a unit is wiped out there is a chance the characters in that unit can be killed off permanently unless you have the appropriate skill user with that group. Also, in 2, Ridley can be killed, depending on the choices you make at one point, and Kiba dies during a mission
Roy in 5, if you stubbornly choose to defend your castle instead of abandoning it. This is not recommended, as unlike Ridley, Roy has no replacement in the 108 stars, preventing you from getting the best ending.
In the first game, it's possible to kill two of Barbarossa's generals rather than recruit them. Which is bad, since both of them are stars. It doesn't help that killing the second general is extremely tempting, since he killed Gremio.
Actually it's not that tempting considering that it was the rune that Windy gave him that forced him to become an unwilling pawn who had no idea what he was doing, or that he had killed Gremio.
Kill It with Fire: Yuber, the series most frequently seen Psycho for Hire, burns a village every single time he first shows up in every single game he shows up in. In fact, his earliest chronological appearance in the series, a flashback to 300 years before Suikoden I shows him burning a village. Dude sure loves to play with fire.
In Suikoden II, Luca Blight practices a 'Scorched Earth' policy of his own: burning down two of the City-State's border villages. Viktor does something similar when he 'accidentally' leaves a bunch of the Fire Spears in the Mercenary Fort's forge. Oopsie!
Leave Him to Me: Usually done in the heroic inversion, with the heroes insisting or agreeing to a one-on-one duel despite outnumbering the enemy, as an excuse to use the game's dueling system.
When you finally get to fight Childerich in Suikoden V, several people on your party (if you have them with you) can step forward and demand the right to duel him alone (since he beat or disqualified them in an earlier fight through trickery); if you have all of them, it results in a comical extended argument over who gets the duel.
Pesmerga and Yuber only join (in their respective games) because the other person is on the other side, and only to get a chance to fight their counterpart personally; in the first game, Pesmerga specifically demands that you Leave Him to Me as part of his condition for joining.
Played straight with the duel between Teo and Pahn in Suikoden I.
Sonya Shulen from the first game is a great example of this.
Chris Lightfellow, one of the main characters from Suikoden III in particular is very strong example
Lethal Chef: Nanami. Her cooking makes Nash pass out in Suikogaiden Vol. 1
Riou is so used to eating it that he's developed an immunity to it. Seriously. When the only reason someone can eat your cooking is because they're immune to it, then you know something is wrong.
Also hilariously alluded to with certain food items. By adding salt to the cake and ice cream recipes, you get Nanami Ice and Nanami Cake. Both have a 60% chance of inflicting the Panic status ailment (though Poison would probably be more appropriate).
Load-Bearing Boss: Happens without fail every time, usually attributed to a big discharge of energy during the battle. Even in Suikoden III, where the fight takes place in a faily big open-air area that still manages to fall on the boss and kill it, while your characters flee to safety... through the underground tunnels.
Oddly subverted in Suikoden II, where the L'Renouille castle begins to rumble immediately after the battle prompting everyone to flee... until then the rumbling ceases and the castle appears to be just fine.
Living Forever Is Awesome: Demonstrated in three where Geddoe holds onto the True Lightening Rune even after a contemporary has given up there's. [[Spoiler: Chris]] also holds onto the True Elemental Rune that she receives.
Loads and Loads of Characters: Just counting the 108 stars gives you over 500 characters in the main five games alone. While a few characters recur between games, the vast majority of the playable cast is new each time.
Loads And Loads Of Sidequests: About half the 108 playable characters in the series are optional, and the optional ones usually have some kind of sidequest that needs to be completed before joining. Everyone seems to think one has hours available to go cooking, fishing, exploring dungeons, backtracking, fetching things, taking them to see people... and even after you recruit them, a number of them still have minigames to play.
Lost Forever: Every one of the Stars of Destiny save the plot-relevant main characters. If you fail to recruit even one of the Stars or allow one of them to die permanently in battle, you can kiss the Best Ending goodbye.
Bizarrely, though, while several Stars of Destiny are absurdly easy to miss — several in each game can usually be missed simply by proceeding in the logical fashion through the plot without revisiting old areas — this trope is generally subverted with nearly everything unique other than Stars of Destiny. Frequently, minor unique items like music or voice sets that you miss the first time around will appear in shops elsewhere as rare finds... this sort of thing does not (generally) happen with the far-more-important missable characters, for some reason, although there's a few exceptions.
Lost Technology: All games reference the mysterious and ancient Sindar race, whose technology-filled ruins and artifacts litter the landscape.
Magic Antidote: Averted in Suikoden V. The Hero's Rune has the power to keep Lyon from dying when she gets poisoned, but she still has to spend a long time in bed recovering.
Modular Epilogue: After the ending cutscene you get a short text statement like this for each character you recruited: the text can change depending on who else you recruited and sometimes actions you took within the game.
Some of the Queen's Knights do not join the prince's rebellion against the Godwins not because of political allegiance but rather their loyalty to the Queen.
Ninja: There are a good amount of these in this series.
Non-Action Guy: Thomas in Suikoden III, despite beig the Tenkai Star of the game, generally lets the others in Budehuc Castle do the fightng for him. He still manages to help out all three of the main characters by letting them use the castle as a base, though.
Hix from 1 and 2 also counts a little, as though he can fight he's mediocre at best, not to mention preferring not to fight whenever possible. Unfortunately the poor guy is engaged to Champion Tsundere Tengaar, who is determined to make him a man and forces him into your party on two different quests to prove his worth.
Nonstandard Game Over: Can occur in many of the games if you make the "wrong" decision (e.g., decide to join up with a villain, or run off and desert your army, etc...)
Not Quite Dead: In Suikoden 2, Nanami is seemingly killed when she is hit by an arrow. However, if certain conditions are met by the end of the game, it's revealed that she merely faked her own death so she could go home, no longer able to bear the war her adoptive brother was fighting in, and particularly the fact that her adopted brother and their best friend are the leaders of the opposing armies. If said conditions are not met, however, she stays dead
Old Save Bonus: For the 2nd and 3rd game, if you upload old data from the game previous to the one you're currently playing, you get some extra goodies. (Some of the library books you collect will have your old character's names and exploits in them, for instance.)
108: 108 Stars of Destiny. 108 divided by four is 27, the number of True Runes.
Valeria and Belcoot, both Falcon-style swordfighters, come with somewhat friendly rivals who join up with the player characters just to keep an eye on their competition.
Subverted with Luc in II, who reveals that he has had the True Wind Rune since he was introduced at the beginning of the first game, and uses it — for the only time it is used in the entire first two games — solely to annoy his counterpart... who doesn't even seem to know who he is, beyond 'that horrible guy who keeps coming after me.'
Promotion to Parent: In a story about war, it's gonna happen to a few characters, most notably with Gremio, Pahn, and Cleo to Tir in I, Riou, Jowy, and Nanami to Pilika in II, and Sialeeds, Georg, and Frey to Lym in V.
Quickly Demoted Woman: Odessa Silverberg, certainly. It also counts as an earlier Player Punch(Though not as hard as Gremio's later...). Also Apple in II, who demotes herself because she says outright that she's no good as a strategist because she's a woman, and has the player go find someone better. The strategists of IV and V are female, though, so it was likely more Apple's own lack of confidence than a statement by the authors.
Reality-Breaking Paradox: According to the series's mythology, the world and the True Runes came about when Sword (who could destroy anything) tried to destroy Shield (who could not be destroyed). Both shattered, and the pieces became the True Runes.
Flare from IV and Lymsleia from V are fairly rebellious as well, though not against their parents, but rather against the enemy forces that invade their homelands. Considering who their fathers are, it's not that hard to believe.
Genshu (Suikoden 2) has similarities to Tachibana Ukyo: they both fight using Iai techniques, their stances both don't face their enemy directly, and both have techniques related Swallows (Genshu's rune, Tachibana's Tsubame Gaeshi) and their most powerful techniques are a series of very fast sword draws.
Wakaba's Tiger Rune animation looks an awful lot like King's Double Strike. Sometimes the animation for that attack instead ends with a Hurricane Kick.
This also gets carried over in a non-sibling relations on Mathiu's students: Shu is arrogant, doesn't have the sense of justice (at first, at least ), but brilliant, whereas Apple is more humble, willing to help people, but... not-quite-so-brilliant.
So Long, and Thanks for All the Gear: Happens horribly often, because the games tend to have Loads and Loads of Characters, and they are frequently called away by the plot; on top of this, the best characters and most plot-critical characters (who you're likely to give much of your best swag to, partially because you're often forced to bring them along) are also often some of the ones who disappear the most often.
Subtext: This is one of those series that practically runs on it. Pick a character, it's practically guaranteed you will find subtext in their interactions with at least one other character. See also: Ho Yay / Les Yay, above.
The Team: Every one of this franchise's games has it. 100% Completion requires having 108 characters on your team, a significant number of which are fighters, and using all their abilities to succeed in certain areas. Go ahead and try to divide them all up into classic character rolls.
Thou Shalt Not Kill: You're given the chance to execute the Empire's generals in Suikoden 1. Spare them, and they become Stars in your army. You're totally allowed to kill Kraze, though, as nothing is lost or gained either way with him.
Tsundere: Tengaar, whose tsun-tsun side would make Hix's life like hell to shape him up as a 'warrior', but her dere-dere side would always get her to depend on Hix's help, in an honest, sometimes gushy, way
Underrated And Overleveled In fact any Role-Playing Games (like Suikoden) that emphasize a massive cast of recruitable teammates tend to be particularly guilty of this. The huge hosts of characters guarantee at least a few will be mundane people with little or no combat training, and the inability to focus much plot on each character means that the developers don't have time to give in story justification for everyone's combat capabilities.
Unholy Nuke: Pretty much all of the Soul Eater's spells.
Unidentified Items: You can pick up ?Pots, ?Paintings and ?Statues which you can take to an art appraiser to have valued and identified, and then either sell or use to decorate your home base. Alternatively, you can sell the items unidentified for a small amount. Anything useful never needs identifying, however.
