* Why did the Winged Dragon of Ra obey Jaden even though he doesn't have an Egyptian heritage? Because Jaden's opponent, Franz, abused it and treated it like a slave, so fighting on Jaden's side would enable it a chance to get back at its owner!
** It's also possible the Winged Dragon of Ra could sense [[spoiler: that Jaden was the Supreme King reborn ]]
** Alternatively, Ra noticed that Jaden possessed Winged Kuriboh, and recognized that this meant that Jaden was favored by Ra's true Master (Atem), or at least his master's long-time partner (Yugi).
* Most of Aster/Edo's Destiny Heroes have names that start with D. Most of the cards' names were changed for the dub; Diehard Guy was renamed [[Music/TenaciousD "Captain Tenacious."]]
** As noted under PunnyName, Yubel's name may trace back to several forms: "juwel" (you-vel), meaning jewel in German; "jubel" (you-bell), meaning happy or joyful in the Scandinavian languages; or "übel", meaning evil. Yubel discovers [[spoiler: that there is no happiness for her in being evil, and that her true destiny is to help Jyuudai to defeat the Light of Destruction, not to take him away from his new Scandinavian (or possibly German--the spelling inconsistencies make either a possibility) friend with a jewel-based deck]].
** Daitokuji may be foreshadowing/making references to the Society of Light arc (somewhat) and especially the Darkness arc. His line, "Everything in this world is born through one substance, which changes variably, creating the sky and earth." is what [[spoiler:Darkness' "The world was born from a single card..."]] speech is based on. And his card, ''The Philosopher's Stone - [[SpellMyNameWithAnS Sabathiel]]'' foreshadows the final opponent of the last arc, [[spoiler:Darkness]], who is the representation of humanity's despair. The hermetic angel Sabathiel is the Angel of Saturn, a planet which symbolizes Nigredo. The Nigredo phase has been interpreted by Carl Gustav Jung as the period of despair.
* When you keep that in mind, a lot of things about ''[[Anime/YuGiOhGX GX]]'' that initially made no sense or just seemed weird suddenly make more sense. For example, the community at tv.com found a lot of the {{Freudian Excuse}}s ridiculous -- Martin making a DealWithTheDevil just because his parents got divorced, Fujiwara being overcome by Darkness and orchestrating the AssimilationPlot just because his parents died... In retrospect, maybe they were ''supposed'' to look ridiculous and show how having some normal sadness or ParentalIssues in your past is a lame excuse for causing TheEndOfTheWorldAsWeKnowIt. Even Edo thought him risking his life to protect Ekou made no sense -- deliberately showing how absurd TheDulcineaEffect is? And, of course, there's Fujiwara needing to use MindControl to get characters to RememberTheNewGuy and Manjoume's BreakTheHaughty arc going so far that it becomes detrimental to him. Basically, the more audacious and over-the-top this show's use of a trope is, the more likely it is that it's actually a TakeThat at the trope or its genre. ~@/{{Lale}}
* I've noticed that whenever people reference Yugi in ''GX'', it's always referring to Yami. At first, I thought that this was shallow, since it references solely his actions in the original series without taking in consideration the time gap between ''DM'' and ''GX''. Later on, I had realized that this ''was'' Yugi--in the time span between the two series, Yugi had changed dramatically from who he was in the start of the entire series. His Yami-like appearance was an artistic representation on how he matured. This to the realization why his face is obscured during the present day--he does look like Yami, but hiding it blocks non-Brilliance'd viewers from thinking Yami might be back.
* The Entire reason that Yugi gives Jaden the "Winged Kuriboh" Card at the start of ''[[Anime/YuGiOhGX GX]]'' is because Yugi knew who he was, as well as the fact that he would use the Kuriboh cards because of the events of Anime/YuGiOhBondsBeyondTime. This is because in the film Jaden uses The Flute Of Summoning Kuriboh. For Jaden, he is meeting Yugi for the third time, but for Yugi, they are meeting for the first time. (The order being "GX:1", "GX:180", "The Movie" for Jaden, but for Yugi "The Movie", "GX:180" "GX:1") This explains why Yugi would give a random duelist one of his cards, as well as why in episode 180, Yugi (the one Jaden duels, in the past) knows Jaden's name, without being told.
** It really is a brilliant StableTimeLoop.
* The names of the different groups were chosen by Kaiba which is why Obelisk is at the top, because it was Kaiba's god card. It also explains why Slifer is at the bottom, because it was Yugi's original god card and Kaiba doesn't like Yugi.
* At first glance it seems like the dub names were chosen at random, but upon realization that all of the first-year students (Chazz, his cronies, etc.) who start off in Obelisk Blue must have gone to DA's prep school, all of the preppy names make sense.
* Before going to Domino City, Sartorius is coldly confessing to Aster that their friendship is only a part of destiny, like everything else he taught him, and Aster's purpose was served brainwashing members, Sartorius has tears running down his face. Strange for the BigBad to be crying while displaying his ManipulativeBastard plan, but later on revealed Sartorius was under DemonicPossession by the Light of Destruction and it was the real Sartorius crying as the Light cut off his friendship with Aster.
* Yubel is an exaggerated ViolentlyProtectiveGirlfriend during Jaden's childhood because she has been the guardian of the Supreme King's vessel for several unknown lifetimes. Who knows what experiences Yubel has encountered trying to protect him from people pretending to earn his trust, or even considering the Supreme King himself can turn out to be evil, Yubel didn't take any chances with whatever Jaden or his friends might believe his best interests are.
* After Zexal's reveal of the Numeron Dragon, Darkness/Nightshroud's speech about the origins of the universe as represented by a single card becomes much less metaphorical in retrospect.
* In the last two episode of Gx, Yugi says to Jaden that he will challenge the most powerful duelist to which Jaden asks if he is stronger than Yugi. I always thought that Yugi is referring to Atem since he's always with him (and the fact that he has the God cards) but he actually might be referring to the combination of him and Atem.
* Judai not knowing what a "fiance" is makes a lot more sense (and shades into FridgeHorror) once you know that a significant portion of his childhood memories were erased.
* Judai's favorite card is a mix between a man and women, part dragon, has an effect that deals damage based on the opponent's monster attack and through a source of light becomes much more powerful and vicious, before it gets replaced by Elemental Hero Neos. Are we talking about Yubel, or Elemental Hero Flame Wingman?
* At first this troper found it odd that Judai's designs for Kaiba Corp's contest were the ones sent to space; after all his drawings weren't precisely the best. Until I remembered that Seto Kaiba said that he would handpick the winners. Why? Because Seto's little brother Mokuba once did a similar quality drawing of a Blue-Eyes White Dragon for him during their childhood so he picked those designs because of nostalgic reasons. May also count as Heartwarming.
* When one looks at the Three Ranks, it actually makes sense that Kaiba would set them up not just because he wants to spite Marik and Yugi (Given they are put under Obelisk, aka him), a lot of the duelists in the dorms represent people that fit their best skills, at least in important roles;
** For Obelisks, the skills are refined to the point of being at the top of the batch and thus have a lot of powerful cards (like Zane and later Syrus), just like Kaiba did at first. However others like Alexis or Chazz use weaker cards with powerful effects, which is also another type of strategy Kaiba uses in conjuction with his powerful cards.
** Marik is a master strategist and tends to think ahead, which is why many Ra students like Bastion or Hassleberry seem to rely more on fine-tuned stategies than anything else, making them able to keep up with them.
** and finally Yugi himself is a bit of an underdog at first, starting out with what was basically a rather hosposh of cards that balanced each other out and is able to go up the ranks. Now, why would that sound familiar considering who the main character is? Not to mention both Jaden and Yugi are MagneticHeroes, being able to make friends with former rivals and get many people on their side.

* In the fourth episode of the first season, Duel Academy has an entire military transport just to protect its shipment of rare cards. It's validated when the captain mentions they've had to fight off "mecha-triggers (something like that) and attack subs". People probably died. Considering the fights people get into using them, this is a world where wars may very well be fought over trading cards as weapons.
** [[spoiler:Becomes worse after watching Arc-V and Academia. It's not hard to imagine that the Government was in on or endorsed the attack on Heartland.]]
** also becomes worse when you remember the Rare Hunters from the original series. They are a dangerous group of raiders...who's to say that, even with Marik reformed, they aren't still around?
* Take a look at the future Darkness/Nightshroud shows Judai in their final duel after watching 5Ds. Seem familiar?
* In season 4, Ryo is twenty years old and has a severe heart condition. His eighteen-year-old brother (who has ''no medical knowledge'' and apparently resents the living hell out of Ryo for forcing him into a caretaker position) appears to be his only advocate. ''Where are their parents'', and what kind of life can they possibly have going forward? Ryo might ''say'' he wants to start over and duel again, but his health is obviously still a major concern.
* Manga: In the final chapter, Ryo is shown in his "Hell Kaiser" outfit from the anime. ''What happened?''
