* The series also indulges heavily in symbology from Judaism. (What's the main characters original name again?) In particular, viewers have noticed that the final duel between Jaden and Yubel closely mirrors a Jewish wedding ceremony. Elements include, the Ketubah (Spell Chronicle), the placing of the veil (Rainbow Veil), the bride circling the groom (Yubel's thorns), drinking from the cup of life (Air Hummingbird's effect), the seven blessings (Rainbow Neos), the breaking of the glass (Duel Academia's windows cracking), all culminating in Jaden and Yubel reaffirming their love as they're united forever by Super Fusion, before retreating away together as in the Yichud.

* Bohman's Neuron Network is derived from the term [[https://en.wikipedia.org/wiki/Neural_network Neural Network]], which are algorithms that are inspired, fittingly enough, from human brains. A Neural Network mimics how a brain processes data via artificial neurons to learn and process data to make decisions, and this fits how Bohman uses all the minds he absorbed as nodes to simulate how Playmaker will fight.

** And the monster that defeats him is Electrum/Elixier, also a reference to alchemy, being the fusion of all four basic elementals to form the ultimate E-Hero, and named after both of alchemy's end goals: the creation of precious metals (electrum being an alloy of gold and silver), and the creation of the elixir of eternal life.

* Each arc also represents part of the alchemical process (though not necessarily in the correct order):

* Each arc also represents part of the alchemical process:

* Revolver's Topologic dragons got their name after [[https://en.wikipedia.org/wiki/Topology topology]], which is the study of the properties of space that are preserved under continuous deformations. This is referenced by their designs having Mobius strip formations all their wings and tails.

* Saiou's Tarot themed Arcana Force deck often has symbolism in his cards that reflect either what is happening in the duel or something about his opponent. For instance, against Manjoume, he uses Suit of Sword X and it stops upright; this represents defeat and the anguish and despair that accompanies loss, but there is also a glimmer of hope for things to improve, like how Jun has repeatedly lost to Judai and is doubting his skills, but he can find new purpose if he joins the Society of Light. When Saiou claims his cards give him insight on his opponent, he's completely serious.

** Citrinitas, the yellow, awakening stage: Yubel's awakening of Judai's past and powers, (giving him yellow eyes as the Supreme King).

* Many attack names and cards introduced are actual terms in computer technology:
** Firewall Dragon's attack name is actually a cyber attack of a technology involving the monitoring (and shielding) of devices. The technology name is called a Telecommunications Electronics Materials Protected from Emanating Spurious Transmissions or "TEMPEST" for short. So the attack on it is called a "Tempest Attack".
** Topologic Gumblar Dragon alludes to the malicious [=JavaScript=] trojan horse file Gumblar (aka [=Troj/JSRedir-R=]) from 2009, which redirects a user's Google searches before installing rogue security software.

* Amnael's Alchemy deck contains six "Alchemy Beast" monsters and Golden Homunculus, reflecting the seven base metals that ancient world alchemists recognized. Meanwhile his Spell cards reference the four stages of the alchemical process, which each had their own name and associated color that are accurately represented by Amnael's cards. When he transitions to his Helios series (which have three forms of escalating power), it's a reference to Hermes Trismegistus, "thrice-greatest Hermes", the man who created the foundations of Hermeticism. Hermeticism teaches there are three parts to how the universe operates -- Alchemy, Astrology, and Theurgy, the study of how the Gods work and a type of magic that is counterpart to Goetia, the study of Demons. This symbolizes that Amnael has mastered Alchemy and Astrology, but the Sacred Beasts/Phantom Demons lay beyond his grasp.

** And the monster that defeats him is Electrum/Elixier, also a reference to alchemy, being the fusion of all four basic elementals to form the ultimate E-Hero, and named after both of alchemy's end goals: the creation of precious metals (electrum being an alloy of gold and silver) out of the four base elements, and the creation of the elixir of eternal life.

** Nigredo, the black, putrefying stage: Nightshroud's plot to break down humanity into their lowest form.

* The names of the members of Yliaster -- Paradox, Antinomy, Aporia -- are named after logical fallacies and impossibilities in Greek philosophy. Fitting given the Yliaster is trying to cause a TemporalParadox. Each name fits their role too.

** Aporia: The confusion resulting from different pieces of evidence supporting different conclusions. Each of Aporia's components are a different take on the same person.

* Z-one's Timelords are based on the elements of the Sefirot. Z-one also summons each Timelord in its order on the Sefirot, and when he has multiples on the field, attacks in that order too.

** And the monster that defeats it is Electrum/Elixier, also a reference to alchemy, being the combination of all four basic elements to form the ultimate E-Hero, and named after both of alchemy's end goals: the creation of precious metals (electrum being an alloy of gold and silver) and the creation of the elixir of eternal life.

* Noah's deck references the creation of the earth from Genesis, adapted to the evolutionary development of the world. He starts with a primordeal wasteland populated by demi-human monstrosities, then a great flood wipes it all out to clear the way for the dinosaurs, until an asteroid impact kills them and allows humans to evolve to dominant life. Discounting his first two turns when he's staying in the primordeal Earth phase, Noah takes seven turns in the duel, his seventh turn being when he summons Shinato as symbolic of God and wins the duel. His second deck being a Spirit deck symbolizes the transition to the afterlife and spiritual plane.
* The word "Orichalcos" is a reference to Orichalcum, the metal said in the original Atlantis story from Plato that was the source of Atlantis' wealth and power. It's unknown which metal Orichalcum actually was, but is generally believed to be some sort of copper alloy, which would fit with the green color of the Orichalcos.

** Antinomy: Two premises that are incompatible despite both being true. Antinomy is both the friendly Bruno and the antagonistic Dark Glass.

* In fact the series has an amazing amount of references to alchemical symbolism. For example, the motif of three suns is an alchemical symbol and a recurring element throughout the series: Amnael's ace monster, the triple suns two of the alternate worlds possess, and Nightshroud's world is a reference to one of the three.
