Expy: Of Jaden, what with him being the fun-loving Elemental HERO duellist.
Fusion Dance: What his deck relies on for powerful monsters.
Master of None: Justin uses one of every (non-fusion) HERO, and his deck seems like it's trying to incorporate a piece of every strategy a HERO deck can use. Unfortunately, this leaves his deck heavily unbalanced.
A student who was semi-willingly sent to the academy by his parents. Unlike most of the students, he cannot sense Duel Spirits.
Adventurer Archaeologist: Anthropologist, more specifically. His parents were these, and he was one by virtue of being dragged along.
Bash Brothers: With Jacques. It helps they both are Machine-type enthusiasts and view each other as equals.
Difficult but Awesome: His Meklord monsters aren't a very consistent archetype, lacking decent support or good effects. That being said, the Meklord Emperors are ridiculously strong in the right situations.
Gadgeteer Genius: Can hack all sorts of technology, such as giving the group's Duel Disks two-way radios.
Motor Mouth: Tends to do this when he focuses on one particular topic, in addition to not paying much attention to other things around him. He consciously takes advantage of this to ignore pain.
A young boy of dual British/Swedish decent, as a young child he would often listen to his great-grandfather's stories which he still remembers to this day. He always wears the two gifts his great-grandfather gave him before passing on a peaked cap and a trenchcoat.
The only son of a pair of bank robbers, Denero lived with his uncle in Italy after their arrest, learning the ways of the Jurrac deck. He now attends East Academy with his aggressive Duel Spirit Jurrac Meteor, who uses Denero’s body when the time comes to duel.
All Take and No Give: Denero is dependent on Jurrac Meteor, a fact that the meteor uses to take control of Denero’s body to do whatever it wants.
Apologetic Attacker: After regaining his body Denero will normally apologise for the actions of Jurrac Meteor during the duel/discussion.
Gollum Made Me Do It: The relationship between Denero and Jurrac Meteor, with one being timed and unsure, and the other being aggressive and angry.
It's All About Me: Denero has, as part of his levels in jerkass, become incredibly arrogant, and pushes his opinions and demands on others in exchange for aid.
The Other Darrin: After a several month hiatus Denero's original player gave control of him to a new player. So far the change hasn't really effected the characters in the story or the other players so this trope might just be Averted.
Properly Paranoid / Jerkass Has a Point: While his reason's for not trusting the Headmaster is understandable, the fact that he seems to be wasting time giving him the third degree has not endeared him to the others.
The Rival: Seems to have taken a strong disliking towards Marcus. The fact that his parents once stole from Marcus's company doesn't help matters.
Took a Level in Jerkass: After the duel with the cultists, he has become a lot more aggressive and uncaring towards his fellow duellists. Likely due to him merging with the other Duel Spirits.
The son of the wealthy Kyleman family, Marcus is probably the most... "unique" duellist in the academy.
Alien Invasion: He uses an Alien deck. Particularly, they specialize in taking over monsters, mainly for one effect or another, or even just to destroy them with Alien Hypno.
All the Other Reindeer: Zig-Zagged. He was never really bullied at school, and he kept himself seperate from others because he knew that they found him weird and didn't really want to talk to him. He doesn't really care about having friends, but there are hints that it's a desire that he's regulated to "Never Going To happen".
Aloof Ally: Played with, minus the Badass aspect. While he's happy to help the group and is reasonably polite to them, he doesn't really consider himself to be part of the team, and considers their alliance to be more along the lines of a business deal; it's exaggerated to the point where he is legitimately shocked to hear Sigmund call him a friend.
Anti-Hero: Although Marcus is normally a nice bloke, if a bit aloof, he has an incredibly ruthless side.
Berserk Button: Never bully someone in front of him, and if you do, and you continue to belittle others, then pray to God that you can back it up or Marcus will destroy you. As Gretel found out the hard way.
Beware the Nice Ones: He went from being affable and friendly... to trying to break Gretel. Needless to say, many of the other students were shocked by this transformation.
Blue and Orange Morality: Marcus seems to operate primarily on this. He's friendly and polite, but is genuinely unable to understand why mind raping and executing an enemy would be considered a bad thing. Somewhat understandable when you consider that the only companion he's ever had is a Starfish Alien literally designed for war.
Boring, but Practical: He often uses moves that are simple but effective, something that Gretel mocks him for.
Butt Monkey: He seemed like this in his first two duels, being Curbstompedtwice and failing to inflict any damage in either duel. However...
The Chessmaster: Marcus almost ALWAYS has a plan in everything he does or says.
During the duel with Gretel, he used Obfuscating Stupidity both to lure Gretel into a false sense of security, and also to simply annoy the crap out of her. (She had really pissed him off with her arrogant attitude before the duel, so he was trying to not just beat, but humiliate her) When Marcus saw the face-down cards on Gretel's side of the field, he was almost positive that they were traps. However, he also realized that it was better to spring them now, and lose a weak monster, than to spring them later and lose one of his trump cards. Furthermore, he also had three separate traps of his own that he could use to counter her retaliation. Now, if he were to use the same cold, confident and eloquent attitude he had been using in the previous duels, then it would be obvious to Gretel that he had a plan. And Marcus knew that Gretel was intelligent enough to easily figure it out. (After all, if he could figure it out, then so could she.) But by acting like a fool, he could make his reckless actions look like the work of an incompetent amateur who didn't know what he was doing. Furthermore, by being as annoyingly retarded as possible, he manipulated Gretel into wanting to end the duel as quickly as possible, which meant she would be quick to play her strongest monsters in order to take him down as quickly as possible, little knowing that he had a surprise waiting for them. His plan worked perfectly. She wasted her backrow and Mystical Space Typhoon on cards that could easily be replaced, and in her impatience to end the sham of a duel and shut up the babbling idiot, she threw one of her beloved Xyz monsters right into the path of a Mirror Force. leaving Alien Hypno free to attack her directly.
On a larger scale, Marcus was also setting up a Heads I Win, Tails You Lose situation. If Gretel lost, then she would have just lost to an idiot, but if she won, then she would have just wasted half an hour of her time.
During the finals of the tournament, Marcus tricks the others into believing that his partner can read minds. This leads Denero (Who is terrified that Marcus will recognise him as a son of thieves and expose him to the other duellists) to try and turn the others against Marcus. Both Denero and Jurrac Meteor believed they had outwitted Marcus, but it was in fact the other way around. Marcus lied about Gol'gar's mind-reading ability in order to gauge the reactions from the others, knowing that the ones who panicked would be the ones with something to hide, and Denero had fallen right into his trap.
Obfuscating Stupidity: This is essentially Marcus's signature tactic. By feigning incomptetence, he is able to gain an advantage over his opponent without the opponent ever realising the danger they're in until it's too late. Shown best in his Curbstomp Battle against Denero's father. Ironically, that particular duel also Deconstructed this trope, as his own partner began to lose faith in his ablilities. See Nice Job Breaking It, Hero on the main page.
Parental Neglect: While they genuinely love him and were never abusive, Marcus' parents never knew how to "handle" his quirks when he was growing up, and with the demands of their jobs, this lead them to be quite distant, leading Marcus to believe that everyone considers him a burden.
"I am your biggest fan!" / "You know nothing, and so you understand nothing."
A student at the Academy who always wears sunglasses, has spiky hair, and is possibly one of the only normal guys in the cast. He seems to have a thing for Crystal. However David has shown a slightly darker and more Badass side to his personality. He curbstomped Denero into dust, completely turned his appearance around, and he appears to have a few more internalized...problems...than we thought. He claims to be an "Apophis Guardian", and was the one who told Avrum about the threat posed by Apophis. Even so, there are numerous mysterious facts about his personality, let alone his bizarre habit of sneaking around the Academy.]] Then again, considering that the cast of this show consists of, at last count, a borderline sociopath, an 'Outseer', a 'Dualmind', multiple people with Duel Spirits, a hacker, a thief with a dark past, a boy possesed by an evil sword and another who can somehow fight Shadow duels despite not having a spirit, David is still probably the closest thing to a normal person at this school.
Ambiguous Allegiance: It is very, very difficult to tell which side he's on, if he has one aside from his own, or what kind of person he really is underneath all of the false fronts, lies, and guileful behavior. Even his answers have vague meanings, and could be construed differently.
Ascended Fan Boy: He gets to hang out with the duelists fighting Apophis, and he is, as stated, their biggest fan.
Not afraid to stand up against a scary Denero for the girl he seems to like, even less scared to tell him in a frank manner why he sucks, and then Curbstomp him. And that was when David was at his weakest.
He even takes a stand against Apophis during the finale of the Apophis Arc.
Cloudcuckoolander: He has a strange train of thought. He tends to say very odd, random things, and contributes to conversations in odd, inexplicable ways.
Cool Shades: David is never seen without his cool shades...
Sunglasses at Night: Even when he probably doesn't need them. Come to think of it, we've never seen David's eyes...
Cowardly Lion: In large groups, he seems shy and awkward. When he's in less packed spaces, he is far more courageous. Subverted, though, in that this is an act.
Crouching Moron, Hidden Badass: Cowers and acts afraid in his second or so appearance, and then he combines two powerful card effects in his first duel, making a powerful lock on his opponent. And he's even summoned Dark Magician, and used that and a powerful and competent strategy to disable and lock Denero down, and then quickly destroy him.
Functional Magic: David is apparently capable of some sort of powerful magic, enough to hurt Apophis.
Glowing Eyes of Doom: Before using some sort of spell to help the group fight against Apophis in the finale.
Hidden Depths: It seems there is definitely more to David than meets the eye. And he definitely knows a lot more than he says. He is apparently very devoted to making sure the heroes face Apophis, but is willing to do anything to make sure this comes about. He also spies on people, and seems to have hidden a lot of issues.
I Need You Stronger / You Are Not Ready: He wants to try to duel Denero again in order to try to make him less of a jerk in order to make the party "complete". Though it has the nasty caveat of David inwardly threatening to "discard" Denero if he doesn't shape up.
It Amused Me: Apparently, his real reason for flirting up a storm with Crystal is because he was either bored or he needed something to do.
Master Actor: He conceals his more courageous side under the guise of a cowardly nerd, and even this is revealed to be an act, in that he's actually vastly more guileful and powerful than we thought, and used the image of a secretly courageous person for his plans, whatever they may be.
Beware the Nice Ones: Despite playing nice, it has been shown that David is a lot more deadly than he looks.
Obfuscating Stupidity: He seems to be a somewhat dimwitted, cowardly sort when being watched by others, and who can only be courageous when fighting to defend a girl he likes. This front was momentarily dispelled when he became quite serious at the end of his duel with Denero, dishing out a very brutal Reason You Suck Speech. And ever since then, he simply stopped being quite so ditzy and cowardly, and has become more mysterious.
Shout-Out / Expy: In general, he seems reminiscent of Shingetsu Rei. He is aloof and mysterious, while pretending to be goofy and unassuming around others, and has shown hints of a darker, more mysterious side of his personality. He even calls himself a "Apophis Guardian".
Straw Nihilist: David seems to view the empty void created by Apophis as very interesting, and only reluctantly aided the heroes. It certainly does make his true allegiances harder to ascertain.
Tall, Dark and Handsome: Its really amazing what some hygiene and proper bodily posture can do. David first looked like a barely washed basement dwelling geek, but after combing his hair, washing his face, and adjusting his posture, turns out he's quite muscular and tall, and impressive looking.
Fridge Brilliance: It is likely because of that incident that Haine has begun executing any cultist that loses, since before he killed him, Marcus had Gol'gar read the cultist's mind to gather information on them.
A strange young child who seems to work for the Cult of Apophis, he mainly appears to spy on the heroes, and gave out certain cards to his allies. Otherwise, he is basically a normal kid...or is he? Haine has also given some disturbing cards to the Cultists, and despite working for Apophis, its hinted he has his own agenda.
Arch-Enemy: While Haine is an enemy of all the duelists, his enmity with Marcus is far more personal than any of the others. While Haine seems to find most of the duelists amusing playthings, Marcus is the only one he genuinely despises thanks to Marcus's taunts managing to get under his skin. Conversely, Haine's torture of Marcus and murder of Sylvestre, has given Marcus his first real personal stake in the war.
Ax-Crazy: Oh yeah! While most of the cultists serve Apophis for selfish gain or because they've been Brainwashed, Haine serves because he simply enjoys hurting people.
Big Bad: He's apparently the leader of the cultists, and the most dangerous enemy the duellists directly confront.
Call Back: To Yami Marik, even going so far as to use his Fiend/Immortality deck. Since it appears that he is Yami Marik somehow placed in a child's body, this makes sense.
Combat Sadomasochist: Par for the course with the cultists really, but he takes it several steps further.
Not-So-Harmless Villain: He mostly just stood around shouting and saying random things, with no real consistency to his arguments. However, he is apparently some sort of Evil Sorcerer, he is currently duelling Marcus and Sylvestre, and he apparently uses a nasty deck full of traps. And then there's how he's completely dominating two duellists at once, torturing them both while keeping his better plays to himself in order to extend the suffering. Not to mention what he did to Gol'gar.
Older Than He Looks: Its hinted Haine was around during Battle City, and somehow knows about the battle between Seto and Yugi and Umbra and Lumis.note More interestingly, he also knows that Seto is the reincarnation of Set. And calls them Yu-chan, Set-chan, Mask 1 and Mask 2.
Really 700 Years Old: With the question answered that Haine is Yami Marik, and the knowledge that Yami Marik said that he was waiting for one thousand years, the question still remains...what is in this child's body?]]
And he most definitely was involved with how the Cultists ended up, in the case of Skull Knight, turning him into an abomination, and in the case of the big cultist, prolonging his life, all using a card called Hatred Battle Booster.
Torture Technician: Just like in the original series, his deck is based around inflicting as much suffering as possible. A task he takes to with gleeful relish.
Troubling Unchildlike Behavior: What, exactly, is a kid doing seemingly living with the Apophis Cultists? And what is more, those cards he gave out have some outright disturbing names and effects. And then there's all the torture and the Mind Rape he partakes in...
Took a Level in Badass / Adaptational Badass: In the original series Yami Marik, while still threatening, was more dangerous due to the fact that he had an overpowered card, rather than any actual skill on his part. In this series however he has long since lost the card, and yet he still manages to utterly dominate both Marcus and Sylvestre.
And then he switches to a larger and more powerful XYZ Deck made purely to kill his five enemies as quickly as possible, using many cards used by the Barian Invaders of Yugioh Zexal. Ironically, this deck ends up being easier for the duelists to beat.
Apep / Apophis
The being that the cultists worship, Apophis is the Serpent God of destruction, and the Ultimate Evil of the ancient Egyptian mythology.
No Nonsense Nemesis: Apophis DOES NOT fuck around. Not even bothering with formalities, It annhiliates the characters and their entire planet without hesitation. When their souls manage to somehow maintain awareness despite the loss of their bodies, It creates entire worlds, specifically designed to break their minds. When THAT fails, it forces their duel spirits to be it's vessel as a form of psychological warfare.
Characterization Marches On: Originally, Gol'gar was portrayed as a Psychopathic Manchild that spoke solely in Word Salad. However, this was toned down significantly. Justified in-universe as Gol'gar's mind fluctuating temporarily when his connection between the two worlds faltered. He looks forward to it happening again.
Combat Pragmatist: Even more so than Marcus. To the Alien Race, the concept of a "war crime" is completely nonexistent. As they see it, they're trying to protect their allies and therefore they should do what ever it takes to win. This includes Mind Control, Mind Rape, biological warfare, experimentations on their own people, even genocide (The enemy's not a threat if his entire population has been reduced to glass).
Foil: His personality, outlook, and relationship with his partner is almost the exact opposite of Jurrac Meteor. Surprisingly, there's been very little interaction between the two.
The tournament organizer and an industrialist, Ravvas seemed to expect something out of East Academy...and knew that they were the ones who defeated Haine and Apophis, by unknown means. What this means about him is unclear, but his personality and preferences are clear enough, so it seems.
Fiction500: Basically owns the existing Island of Capri, having purchased the island from Italy.
Smug Snake: Looks down upon the heroes, and clearly doubts they are the same people who struck down Haine if they behave the way they do.
