History Fridge / YuGiOh5Ds

** Carly gets a Dark Synchro in ''[VideoGame/YuGiOhDuelLinks Duel Links]]'' in the form of Fortune Lady Every.

* 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 cyborg he'd have to either ''sit in it backwards'' or ''lie down like on a toboggan''.

* Yusei's known in the fandom for being the first Yu-hero to have never turned evil or been possessed by evil at some point prior to Yusaku, along the lines of Oricalcos Yugi, Supreme King Jaden, Dark Zexal Yuma and Astral, and Berserk Yuya/ZARC-possessed Yuya. There are some possible reasons for this.

** If one counts the Supreme King half of Jaden as an alternate personality, Yusei is the only protagonist to go through the entire series without another person bound to them in some way or another. These personalities and people are generally responsible for the dark modes either by possession or corruption (Yami Yugi played the Seal of Oricalcos, Astral was the one who fell into darkness and possessed Yuma for Dark Zexal, and the Zarc Fragment was present in Yuya from the start and did possess him at a few points), which by lacking Yusei did not have an avenue for corruption. While similarly 'never went evil' Yusaku had a partner, said partner could not take over him like Astral could and when said partner become an antagonist he ''left'' instead of using Yusaku's body.

* 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.]]

* Jack's and Carly's duel is the only Signer vs. Dark Signer duel with nobody around to watch or try to intervene. This not only makes Jack's situation more suspenseful because he truly is on his own, but makes their interaction feel a lot more intimate and personal -- appropriate for a duel that's all about romantic feelings.

* Z-ONE is the first franchise BigBad to have a ludicrously overpowered deck, and this is because, as the last man on Earth, any counterfeit card he makes is legal by default, since there is no authority to state otherwise. So he made all his cards PurposefullyOverpowered to all but ensure a win.

* The initial four Signer Dragons all reflect the character of their user. Stardust Dragon sacrifices itself to protect other cards from destruction and then returns to the field, in the same way Yusei is always putting himself at risk for the sake of his friends, and in his duels constantly gets pounded but gets back up to keep fighting. Red Dragon Archfiend destroys all the opponent's defense monsters when it destroys one of them, and destroys its owner's monsters that didn't attack, reflecting Jack's ruthlessness, devotion to power, and the betrayal of his friends to succeed. Black Rose Dragon destroys all cards on the field and saps the attack of enemy monsters to zero, representing Akiza's initial character traits, namely her borderline OmnicidalManiac tendencies and love of causing pain and suffering. Ancient Fairy Dragon allows the special summoning of monsters and recycling of Field spell cards, reflecting Luna's bond with duel monster spirits and their world. Black-Winged Dragon symbolizes Crow's ParentalSubstitute status, but the effect to not only undo Black-Winged Dragon's ATK loss, but deal damage to the opponent while he's at it is a clear nod to his TheTrickster status.

Life Stream Dragon's effect to restore and protect the life points of the player and their allies is a pretty good reflection of Leo's desire to protect Luna above all else.
