History Fridge / YuGiOh5Ds

* Here's one people do not seem to have noticed. All this plot armor, which becomes especially evident against Team Unicorn (but also affects other duels, which are interrupted before their obvious finish, like the one against Sherry)? It is because Signers cannot lose against non-Signers (or people with similar powers, like Team Ragnarok or Yliaster ,anyways), so it is actually justified, even if it is somewhat unsatisfactory, and creates no plot hole or idiot ball, just the orders of fate.
* More Fridge Hillarious, but if you look at the way Jose mounts his Duel Runner, in order to do so without revealing he's a [[spoiler cyborg]] he'd have to either ''sit in it backwards'' or ''lie down like on a toboggan''.

** And then Yusei destroyed Wisel, with Goyo Guardian in it. [[NiceJobBreakingItHero Way to go Yusei]].

*** After Arc V's reveal of the multiverse, we can simply assume that GX (Fusion Dimension) never occured in this timeline (Synchro Dimension), leaving plenty of time for Synchro Summon to be invented, Zero Reverse to occur, and Ushio to join the force.

* Zone claims to be a God and thus untouchable. Team 5D's counters with what Yusei calls their 'evolutions proof'. Religion destroyed by proof of evolution?

* I recently had an epiphany that made ''{{Yu-Gi-Oh 5Ds}}'' about ten times more heartwarming. The realization was: the concept of "family" in Satellite is the same as the concept among WesternAnimation/{{gargoyles}}. In a world where survival is such an uncertain thing and the likelihood of parents not outliving their offspring's childhood is high, blood ties get disregarded. It's just not a viable way for their society to function, so they don't form bonds based on blood any more than gargoyles care about whose biological offspring their clan's hatchlings are. Circumstances have forced "families" to form in other ways, or no one would survive. People like Martha, Pearson, and Crow aren't just {{Parental Substitute}}s -- they're ''parents''.

* Relating to the Machine Emperors/Meklords: It's heavily implied that if the duelist loses to any of them while their sycnhros are inside it, they're possibly gone for good. For instance, Ushio's synchro is never seen used again since Wisel's debut (implied to have been pulled in by its effect), Yusei and the twins are desperate to get their dragons back before their life points are gone, and it is mentioned the synchro summoning style is what caused things to hit the fan and want them ''gone''. It seems natural that the synchros stay captured if the duelist loses or [[AndIMustScream worse]].

** On a similar note, I was wondering why Z-One would trigger Zero Reverse by telling Rudger to look into the old Momentum, knowing that it would release the Dark Signers/Earthbound Immortals, who had a 50-50 shot of destroying the world, which is what Z-One wanted to prevent. Rex, all the while, is encouraging the Signers to defeat the Dark Signers, and then he becomes one himself, wanting to destroy the world and build a new one. Why would Z-One allow this? But then I realized something. Rex was seen talking to a shadowy figure long before becoming a Dark Signer, just like the one that talked to Rudger. What if this figure was ALSO Z-One, and Rex's plan to recreate the world was just another of Z-One's attempts to save the ruined future? This theory was almost cemented in my mind when [[spoiler:Z-One's backstory is given in 149, and his computer with the research on Yusei]] only lists FIVE Earthbound Gods, not SEVEN, which suggests that Rex never became a Dark Signer in Z-One's timeline.

** Especially when you consider that most monsters are sentient in this franchise...

** Given that we've been told Zero Reverse happened roughly 16-17 years before the main plot of 5D's, Zero Reverse should've happened some time ''during the Battle City Tournament''! Considering that during Zero Reverse, there was a quite fierce storm, and during the Battle City Tournament, there were some quite fierce storms too, every time Slifer or Ra showed up, there might be some truth to those claims... Though not a single building was destroyed during the Battle City Tournament (not counting Noah's island, since that was filler)...

** It's worse, GX was 10 years after DM, and everything was still cool. So that means everything went to shit in less than '''''SIX'''''.

** Considering Ushio is still alive...

* Remember Joey's cousin from the street duels? The fact that he looks exactly like Joey imples that he is the same age that Joey was in the original series, which allows us to guess at how much time has passed since then. Joey was sixteen in the original series (according to the Yu-Gi-Oh Wikia anyway.) If Joey's cousin wasn't born yet in the original series (which might be assumed from the fact that Joey never mentioned him), that would mean that fewer than sixteen years have passed since the original city. In other words, the Yu-Gi-Oh world went from a reasonably peaceful place to a socially-stratified world defined by a grossly unequal caste system, complete with a police force whose sole purpose seems to be maintaining the oppression of the lower caste, in fewer than sixteen years. Suddenly [[HarsherInHindsight that throwaway gag involving Joey's doppelganger doesn't seem so funny anymore.]]

* Re-watch GX when Darkness shows Judai a vision of the future. Seem familiar?

* Bit of FridgeBrilliance from [[Tropers/{{SongstressKitsune}} this troper]] related to 5Ds: Bruno has no eyeshine. Usually, when a character has no eyeshine, it means either they're background and the artist was being lazy, or that their "spark of life," as one of this troper's friends called it, has gone out. Considering that [[spoiler:Bruno is a robot]] this makes PERFECT SENSE.
