The main character, and your standard teenaged fantasy protagonist, complete with sheltered upbringing in a fairly isolated hamlet and Disappeared Dad. While collecting scales for his girlfriend's necklace one morning, Serge stumbles into a bizarre portal and winds up in an alternate dimension, where his friends and family no longer recognize him. As an infant, he was brought into contact with the Frozen Flame as the result of his ship being blown off-course. With no other survivors in the lab, Serge was automatically designated the Flame's Arbiter, or controller; this effectively locked FATE out from using the Flame. FATE needs Serge's body in order to bypass the failsafe.
Chick Magnet: As revealed in the Multiple Endings. Serge is heavily implied to wind up with Kid in the main ending, and in others explicitly hooks up with either Leena or an early-game shopkeeper NPC. Harle may or may not get in on this too, depending on how much you read into her thing with Serge-Lynx.
The Chosen One: Lynx addresses him as the "Chrono Trigger," and the Dragons know him as "the Arbiter of Fate."
Whodunnit To Me: Serge is on record as drowning off the coast of Opassa Beach. In truth, he was murdered by his father, who was acting under the control of FATE.
Why Did It Have to Be Cats?: He was attacked by a panther as a child, and is terrified of cats. Not only is his mortal enemy a hulking cat-man, but El Nido is swarming with cats, and Serge even gets turned into a feline at one point! Not to mention suffering a Grand Theft Me that leaves him stuck in the body of said cat-man enemy. Oy.
A feline demihuman and Kid's archenemy. Currently serving as shady advisor to the Acacia Dragoons, promising to lead them to the Frozen Flame. For reasons unknown to Serge, Lynx is actively seeking him out. He was originally Serge's father, Wazuki, before becoming FATE's servant. FATE reshaped him to resemble the panther that attacked Serge as a baby. He managed to kill Serge once already, but this was not sufficient; another universe branched off from that event, with a duplicate Serge still running around. FATE's Plan "B" is to possess Serge's body in order to get at the Frozen Flame.
Abstract Apotheosis: In her letter to Kid, Lucca expresses worry that someone, somewhere, is going to exact revenge on all of them for erasing Lavos' timeline, along with all the people in it. Lynx could be considered to be an embodiment of said people.
Defeat Means Playable: In a twisted way. After defeating him for the second time, he switches bodies with you. A consequence of this is that none of your previous party members will work with you, because they believe you are Lynx or just think it's too weird to work with the body of their previous enemy.
Deuteragonist: Inverted — Lynx succeeds in stealing Serge's body and then traps Serge in his own, effectively becoming Serge.
Disc One Final Boss: One of two. Fittingly, his counterpart in Home World is his old shipmate Miguel.
Double Reverse Quadruple Agent: Different versions of Lynx curry favor with both the Dragoons and the Porrean Army. In Home World, he served as an agent of Porre and helped overtake El Nido. As such, he is highly unpopular in that dimension.
Evil Costume Switch: Dark Serge trades in his threads for Lynx's signature outfit, complete with hat and cape.
I Know What You Fear: When Wazuki fully succumbed to FATE, his appearance changed to suit Serge's greatest fear: a panther.
I Want Them Alive: To Serge. Naturally, Lynx does not want his prize damaged. He could care less about Kid, though.
Implacable Man: He will pursue Serge to his limits, which are considerable.
Impossibly Cool Clothes: Although one must question the wisdom of wearing such heavy clothing in a tropical climate when you already have fur.
In the Back: What awaits his boss, Lord Viper, at the top of Fort Dragonia.
Involuntary Shapeshifter: As an emissary of FATE, Wazuki was transformed into a suitable assassin to kill Serge. Once in close proximity to the FATE supercomputer, Lynx is reshaped again into a feminine personification of FATE.
Knife Nut: Apart from the scythe, Lynx carries around some throwing knives.
Large and in Charge: When a 6'4'' cat-man in black and a spiky hat gives orders, people tend to obey him.
Luke, I Am Your Father: It is revealed posthumously that he is Serge's father, Wakuzi, corrupted beyond recognition.
Though this is revealed so late in the game that one wonders why they even bothered.
Meet the New Boss: Like Glenn and Luccia, Lynx is a deliberate throwback to one of Chrono Trigger's characters — in this case, Magus.
Mobile Menace: He dawdles at times, but he still has a tremendous lead. Especially when he beats the heroes to Chronopolis.
Not So Similar: Despite the similarities, there are still considerable differences between the two. Magus was an Anti-Villain who considered the party to be a (sometimes worthy) obstacle to dealing with his real nemesis, Lavos. Lynx, on the other hand, is a straight villain who goes out of his way to make his conflict with Serge personal.
Obviously Evil: Wears black. Spiky garments. Talks in quasi-philosophical terms about fate and destiny. Yeah, think we got our villain.
Strike Me Down: The second bout with him in Fort Dragonia is a ruse to weaken his body to such an extent that Serge will be helpless after they've switched places.
That Man Is Dead: He actually says something of the sort: "On that day, ten years ago, the world was torn asunder. And part of me, in fact, died," but by that point, there had been no hints as to who That Man is. The Reveal doesn't happen until a while after you kill him.
Villain Ball: So, uh...Lynx, is there any reason you brainwashed Kid or waited to undo Robo's lock until after Serge showed up? Or was it just so he could watch you do it?
The alternate endings, with one notable exception, portray Lynx as doing nothing important or pointlessly wasting time since Serge is no longer on his quest. So yeah, it seems he really did just want Serge to see him do his evil deeds.
Dark Serge wastes a good deal of time tear-assing around El Nido and wreaking havoc.
Killing Serge in the first place was a stupid gamble in retrospect, as he essentially stalled himself for 10 years. Killing Lucca, assuming that's how things really happened, also caused him trouble down the line.
Villain Cred: Lynx enjoys a degree of this. The Porrean Army addresses him as "Sir Lynx," despite not holding an actual rank over them.
"I appreciate your help, General. However, I no longer have any need for you. This fort shall serve as a fine grave marker for you and your dragoons. May you rest in peace."
"I'll kick yer sorry arse so hard you'll kiss the moons!"
A hotheaded but good-hearted thief who comes to Serge's rescue after he is attacked on Cape Howl. Though Kid insists that Serge needs a bodyguard, she is merely interested in Serge's connection to her hated foe, Lynx. Kid is the self-made clone of Schala from Chrono Trigger, who was assimilated by the Time Devourer following the fall of Zeal. Kid was conceived in response to Serge's drowning at the hands of Lynx. In traveling back in time to prevent Serge's murder, Kid caused the Home World dimension to splinter off from the 'real' world.
The Not-Love Interest: Interestingly for a lead female character, it's possible for Serge to never befriend her at all! Aside from some mild teasing ("And don't go tryin' any funny stuff just coz I'm cute 'n all!"), there isn't much suggestion of romance between her and Serge. Until the epilogue, where Kid "merges" with Schala, and we're flat-out told that she and Serge are destined to be married in the future.
Plucky Girl: Despite all the hardship she endures before and during the game, she's able to maintain a spunky attitude and not lose sight of her goals to avenge herself or find Serge wherever he might be in time and space.
Rescue Romance: Zigzags a bit between her and Serge. She shows up to rescue him from the Devas, then he rescues her (or not) a few times himself over the course of the game.
Replacement Goldfish: Once he assumes Serge's identity, Lynx promptly places Kid under a spell and forces her to follow him, like Harle.
Revenge Myopia: She will try to kill Lynx no matter the circumstances. Even if the "Serge" she's hanging around is clearly evil and blatantly states who he really is in front of her, while "Lynx" is acting suspiciously nice and... quiet.
You Killed My Sister: Lynx killed Lucca in the process of burning down the orphanage, or so she believes. It's the simplest outcome, but there is room for doubt.
Serge's childhood sweetheart. Until Kid shows up, of course. In order to recruit her, you have to turn Kid down three times after you first meet her, otherwise she is Lost Forever as a recruitable character. When Serge meets the Leena from Another World, she does not believe him to be the dead Serge but a boy with memory disorder; she joins the player's party to help him recover.
Disappeared Dad: Her father, Miguel, disappeared while taking Serge to see a doctor in Marbule. Because she is locked out of the party when Serge encounters him and Serge isn't about to tell her about it, Leena never gets any closure regarding this.
Fiery Redhead: In both dimensions, her sister Una points out that Leena is prone to temper tantrums.
""Humans are, like, totally powerless, dude! With crafty knowledge we may extend our lives a fraction, but we just extend our suffering, too. But in reality, all we can do is leave ourselves in nature's hands and die the way nature intends us to... That is the awesome truth!? Gnarly!"
A hippie-styled physician from Guldove, although he laments not being able to help some of his patients. He'll join you if you opt not to save Kid, wishing to become a better doctor in the journey.
The Atoner: In his past, a tragedy struck someone close to him and he was unable to save the person; this prompted him to take up the study of medicine and open his own clinic.
Combat Medic: He's actually pretty effective at the combat part, too.
A pirate. What more needs to be said? Originally a merc for the Dragoons, Fargo had a major falling out with General Viper, inspiring Fargo to become a marauder full-time. Lynx later fell in with Viper, causing problems for Fargo and his crew. They engendered the legend of the Ghost Ship to avoid detection, and used it to terrorize the high seas.
Character Select Forcing: By the time he joins, he's the only ally that can steal. You'll need him if you want the elemental plate armor, which can only be acquired by stealing from several bosses. Also, he's required in the quest to liberate Home World's Marbule.
Cigar Chomper: There's one constantly between his teeth. In his strongest tech he blows a smoke ring after finishing it.
The Pirates Who Don't Do Anything: (Another). While badass, there's not a lot of raping and pillaging going on aboard the S.S. Invincible — in fact, the pirate Fargo is less of a crook than the version of him that's supposedly running a legitimate business. This is Lampshaded at the end of his introduction sequence, when he waxes philosophical about the damage human beings have wrought on the planet, and your characters comment that they never expected to hear that sort of talk from a pirate.
That Man Is Dead: Home's Fargo says this to Irenes when she questions what happened to the idealistic man who loved her sister and tried to bring peace between humans and demi-humans. Turns out he isn't dead, just in need of a major kick in the pants from his alternate self.
A young knight, and Dario's younger brother. He's an excellent swordsman and even has a double-tech with Serge. The path to recruiting him (which requires you to leave Kid to die) has led many a player to exclaim Guide Dang It.
Guide Dang It: He's probably one of the best characters in the game and has plot significance if you recruit him. To get him, you have to choose not to save Kid in what looks like a But Thou Must moment. (Fortunately, she recovers either way, but you still might feel like a jerk.)
Screw the Rules, I'm Doing What's Right!: Not the most dramatic example out there, but he joins the party so that he can investigate Fort Dragonia despite knowing that it could get him kicked out of the Dragoons.
"Wherever there is light, there is also shadow... So it is the light that gives birth to shadow! Ghetz, I now understand, amigo...! But is it too late...?"
Luchador-turned-priest from the Zenan Mainland who, after a rough time on the continent, moved to El Nido to atone. Greco became a wrestler at one point to, as he quoted, fulfill an "appetite for destruction." This dark period was alleviated through the sacrifice of a man named Ghetz, who gave his life to wake Greco up. He is introduced while on an exorcism assignment in Fossil Valley, presumably to get rid of Skelly, whose possessed skull is lying amidst the bones.
The Atoner: He took his current job after killing someone.
Badass Preacher: How many preachers do you know who are qualified wrestlers?
Bare-Fisted Monk: Although how much his wrestling relates to his religious discipline isn't clear.
Gentle Giant: Despite his brawn, he's a very good-natured person and a comforting man of religion to the locals.
Punny Name: His U.S. name, especially combined with Ghetz's young sister, whom he watches over, Romana, is a pun on Greco-Roman wrestling, while his Japanese name is a reference to wrestler Astrud Gilberto.
Religion Is Magic: Upon meeting him, Greco is immediately able to discern Serge's unique nature — that he is "dead" in this world.
Stone Wall: His attack power and accuracy are lacking, but he can take a hell of a beating.
Cyborg officer of the Porre Military, and a much-touted "secret weapon." His creator, Luccia's brother, was killed in a lab explosion while grafting a relic from Chronopolis onto Grobyc's arm. This resulted in Grobyc's deployment being set back a few years. Ironically, his current overseer, Norris, was behind the bombing, as he feared the ramifications of Grobyc becoming too powerful. Grobyc, who admires strength, defects to Serge's party after the latter defeats him in a fight.
Anime Hair: He actually weaponizes it in one of his techs.
A mysterious masked man in Termina. He's one of the three possible candidates you can recruit to break into Viper Manor. Was supposed to be Magus, but they couldn't fit his story in, so his backstory was removed at the last minute. The new ending to Chrono Trigger DS implies he is an amnesiac Magus.
Dub Name Change: His original name is Alf. Janus/Magus' cat was named Alfador.
Easy Amnesia: There are strong hints that he's Magus, but he doesn't remember a bit of it.
Good Costume Switch: Wears flowing white clothing as opposed to Magus' shirtless cape ensemble.
Please Keep Your Hat On: When you first meet him, Guile has entered into a contest with the local Fortune Teller; if he brings back Viper's treasure, she would give him a present. Otherwise, he will have to remove his mask. The Fortune Teller is so freaked out by his real appearance that it costs her 10 years of life, or so she says.
Evil Twin: To Kid, and it's heavily implied that she is Kid's Home World equivalent. Besides having the same general facial contours, they even have identical fortunes read by the fortune teller in Termina (and an identical Catchphrase, although Harle's is Frenchified).
One of the three Acacia Dragoons. He's a bit rough around the edges, but he's not a bad guy really. Son of Zappa, the blacksmith. He wished he was the one that Riddel would love, but she loved Dario instead.
Red Herring: The game leads you to think that he murdered Dario under the Masamune's influence, just like Radius did to Garai. In truth, Dario was the one possessed. Karsh was forced to kill him when Dario attacked first and then threatened to go after Riddel next.
Terrible Trio: Is the Boss figure to Solt and Peppor. Also forms one of these with ZOAH and Marcy.
A young ferryman from Guldove, who provides transportation to and from Termina. He's a bit hard-headed, and reluctantly ends up having to help out Serge and his friends. Has a crush on Kid, and will join you if you choose to save her.
Single-Issue Wonk: He goes from relatively friendly (albeit hot-headed) to a complete and total Jerkass if you choose not to save Kid. Even after his mother calls him out on it note Keep in mind that this was before it was discovered that Serge could travel between the dimensions at will, so it's not unreasonable to assume that Surge might be seriously conflicted on what to and hesitate the way he did, he still doesn't let up...even after admitting that he would be just as conflicted as Serge was.
Pintsized Powerhouse: At just about a meter tall, she is one of the most physically strong characters you can recruit.
Raised by Wolves: To the point that her running animation has her loping on all fours.
A scientific genius of somewhat dubious ethical practice — but for all that she's a bit on the creepy side, on the balance she's more good than evil. While her name obviously evokes Lucca's, she is not an expy of her but rather a colleague, who entrusted her with a letter intended for Kid.
Dark and Troubled Past: It's mostly revealed through conversations with NPCs. Her brother died in a lab explosion, she tried to help Zelbess and Marcy but could only save the girl, and her old friend Lucca was murdered.
Good Samaritan: As is revealed in one of the Multiple Endings, if you chose to leave Kid to die from the poison, her mysterious benefactor who "came from the mainland" and gave Doc the antidote was him.
The Gunslinger: One of the two people who uses a modern weapon like this. (The other is an alien.)
Heel-Face Turn: His Another self mutinies after being ordered to participate in torturing Riddel.
The Mole: Working under Orcha in the kitchen of Viper Manor.
Officer and a Gentleman: Although he appears less high-class than the typical example, he is unwilling to stoop to unethical methods.
You Monster!: His opinion on upgrading Grobyc to be Porre's "Secret Weapon".
Viper Manor's head cook. He gets turned into a monster by the Porre Army but is defeated and saved from descending into total madness. He was also the one sent by General Viper to steal the Dragon Tear from Another World's shrine (presumably because he's a Guldove native as revealed by his Home World self running the bar there instead of Orlha, and his Verbal Tic, and thus would be somewhat Beneath Suspicion). The fact he did this as his normal self (he didn't get fed the Quaffid seeds until after Porre took over) is a good indication of that latent dark side.
Guide Dang It: Getting her level seven tech. Among other things, it requires her sister to die, the dwarves to be killed rather than be given a Heel Realization, and the unborn Hydra baby to not be given a Caesarean, and of course, that you recruit her to begin with.
The Power of Love: Her Level 5 and 7 Techs. Which is odd for the Level 7 tech, considering that it requires you to indulge in Video Game Cruelty Potential; the implication is that it is these losses and tragedies that inspire her to call upon love.
Downer Ending: You never find out just how he died, let alone had his bones scattered all over El Nido, but clearly something bad happened. (Eaten by Draggy's mother?) In Home World he was forcibly recruited by the Porre Army and presumably died in battle.
Ghost Amnesia: He regains more and more of his memories with each bit of him that you find.
A stage magician working on Fargo's cruise ship in Home, in order to pay off his gambling debts. (Fargo, in fact, exploits Sneff's gambling addiction and rigs the tables against him, so as to keep him in debt — and thus servitude — forever.) Is also in need of some serious dental work.
Baleful Polymorph: He can turn people into cats. He gives up this trick after you take advantage of this form.
A Mystic who can use her dopplegang skill to mimic any monster she's KO'd in battle — or any monster KO'd by someone wearing the forget-me-not pot. One of her doppelgangs has a use in a rare Triple-Tech. She is friends with the Fortune Teller in Another Termina. It is also implied she is the one who (at some point before getting trapped somehow in the Dimensional Vortex) gave Sneff the berry that lets him turn people into cats.
Utopia Justifies the Means: Fully believed that obtaining the Frozen Flame would allow him and the dragoons to wipe out Porre, or at least drive them out of El Nido. To this end he was willing to work with the Obviously Evil Lynx and either let him direct what his dragoons did without his knowledge, or follow his orders and then claim not to know about them (i.e. it's never clear if he was telling the truth about not knowing that Karsh had been sent to Cape Howl to capture Serge or if he was lying), and he certainly authorized Orcha's theft of the Dragon Tear from Guldove. He had nothing against Serge or his allies but "nothing must interfere with the plan". Obviously he comes to regrets this and does what he can to make amends for it later.
Hypercompetent Sidekick: Peppor is actually fairly competent, at least by Goldfish Poop Gang standards. However, whatever Peppor does, Solt tends to screw up. Particularly memorably, Peppor once turns up with a BlackHole element, which Solt accidentally steals with a trap element. Peppor gets so angry at this that he spends half of his turns in that particular battle attacking Solt!
Fauxlosophic Narration: A lot of it. Word of advice: you can run away at the start of the battle, save, and come back, so that you don't have to listen to the whole thing every time you try to fight him.
Tragic Monster: Bound to the Dead Sea by Fate, all he can do is wait in the wreckage.
The 14th Grandmaster of the Acacia Dragoons, Riddel's fiance, and Glenn's elder brother. Died mysteriously when he and longtime friendly rival Karsh went on an expedition to the Isle of the Damned...While on the Isle, Dario discovered and was possessed by the evil of the Masamune, and with it tried to kill Karsh. Horrified, Karsh could barely bring himself to defend against him until Dario declared his intent to slate the Masamune's blade with Riddel's blood, upon which Karsh went berserk and struck him down. While in Another he is presumed dead, in Home he survived, amnesiatic but still in (and under) possession of the evil blade. Your party can jog his memory with the right memento, triggering one of the hardest (but most rewarding) boss fights in the game — victory nets you Serge's Infinity+1 Sword, Riddel's L7 tech, a warm fuzzy feeling at the reunion of the star-crossed lovers and, of course, bragging rights.
A supercomputer built by Belthazar out of the old Mother Brain unit. Originally installed to monitor Chronopolis, FATE was left to fend for itself after Balthazar's botched experiment stranded the laboratory in the distant past. FATE, recognizing that it couldn't allow the facility — or the Frozen Flame — to come into contact with past civilizations, took measures to hide its existence by terraforming the El Nido archipelago and colonizing it with her human staff. FATE continues to subtly interfere in the settlers' lives, ostensibly to prevent them from interfering with history. FATE's goal is to possess Serge's body in order to get control of the Frozen Flame again.
