Mr. Universe was broadcasted as an anime 80053 years ago and The☆Luge's manuscript predates the heavily modified manga that served as the basis for that anime which means that The☆Luge has started freezing people and likely planets since about that long ago with Zaion outright stating that he was with The☆Luge for centuries. One can only wonder just how many people or places were affected in the time nobody dared or thought of correcting The☆Luge's misunderstandings and how much time The☆Luge will have to spend unfreezing them. This isn't even going into consequences like Nyandestar's parents and friends missing out on years of her growing up while they remained the same or Zaion's furniture brand falling even further into obscurity during the hundreds of years it was frozen. Many of the people who joined The☆Luge might have aged significantly or even died before ever getting to see their loved ones and homes unfrozen who might still end up suffering from trauma due to the events they went through. It will be extremely hard or even impossible to fix or make up for things like that especially for places and people which have been frozen for longer periods of time since they are presumably not just isolated systems. There might actually be a lot more people than just Zaion who'll hold a grudge against The☆Luge without making it immediately obvious.
Shewbahha's situation is this if you imagine what his life must have been like as part of a species with an extinct food source that can generally only be found as fossils that they need to look for to survive now and the fact that he is apparently alone without any relatives.
Episode 51: Kartumata
The reveal of the people of the Velgear Star Cluster being simply pawns that were created to fight and kill each other over and over again as part of a game has several rather uncomfortable implications if you think about it. It means that everyone there was unknowingly fighting each other for reasons that someone else decided for them and not their own, that the majority of what they presumably thought they knew about themselves and their history is false and that they all have on average died a mind-boggling number of times without achieving any true progress in their war with the sheer amount of time that is implied to have passed since their creation. The incredibly huge number of people that can be presumed to be involved in this only makes this much much worse since Yudias was able to take 8.88 million followers with him without any so much as even implied problems occurring as a result of them not being there to fight in the war which would naturally lead to insanely huge estimations for the total number of Velgearians which in turn isn't taking into account the number of their enemies across the entire star cluster and the previously neutral faction that is Dudi Ducasse.
Episode 52: Yudias is Back!
The episode opens with Yuga about to duel a character who we know from promotional material is going to be a major antagonist this season. And in one of the most stark moments of O.O.C. Is Serious Business in the entire franchise, Yuga's expression is completely serious and filled with stoic determination. The endless ray of sunshine on the SEVENS/Go Rush universe that is Yuga Ohdo is nowhere to be seen. One shudders to imagine what truly horrendous actions this man would've had to have committed to get Yuga Ohdo of all people to stop smiling.
Episode 54: Yuna's Determination
The previous episode showed that being defeated by a Maximum monster meant you got turned into a card, which is bad enough, but Manabu's duel shows that this happens even against the will of the person using said Maximum. And Manabu's reaction shows he was completely unaware of it. This carries very disturbing implication about Phaser, both for how ruthless he is in deploying something similar, and because it makes you wonder how many other subordinates turned someone into a card without wanting to, and what else he is making them do without realizing it.
Every character starts using Equip Spells after they went into space to face off against the "Great King of Terror". You can say they are arming themselves for battle.
In episode 5, Yuamu smirks when Yudias praised Yuhi's monsters. Much MUCH later, on episode 42, it's revealed that Yuamu's High-Tech Dragon deck used to be Yuhi's, before they swapped decks sometime before the start of the series. Which explain why Yuamu smirked all the way back in episode 5 : the Jointech deck used to be Yuamu's, meaning all the way back at episode 5, Yudias actually praised Yuamu's old monsters.
The reveal of Velgearians as "cards that can think" makes Yudias self-identifying with Transamu Rainac and the care he displays for the monsters he needs to tribute in episode 2 quite fitting. The fact that Velgearians were made and designed to repeatedly fight, die and come back to life also parallels how monsters in the game often come onto the field, to the graveyard and back.
In episode 45 Yuamu and Yuhi come to the conclusion that despite his indecisiveness and the amount of time he takes to think Nishaw always makes the right decision. If you consider Dudi Ducasse's neutrality which could easily be viewed as simply the result of indecisiveness before Nishaw joined forces with Yudias, this actually holds up since the true nature of the war as it was revealed in episode 51 would have made picking any side and fighting alongside that side's people a futile endeavor and joining Yudias allowed Dudi Ducasse to help put an end to the whole thing and the potential threat it posed.
It might seem strange for an alien to offer a form of manjū and karintō which are Japanese specialties like Yudias did to Yuhi in episode 52 and one might be inclined to think of it as an artistic liberty or a matter of the Rule of Funny but it begins to make more sense once you consider that the creator of his species was part of a certain someone from Earth.
The reveal in episode 90 of Velgearians all holding galaxies within them and Yuga having modeled the Galaxy type cards after the galaxies in the universe adds another layer to Yudias thinking that Transamu Rainac resembles him.
There is also how Kuaidul and Yudias visually resemble each other and are both each represented by Transamu monsters based on the same galaxies that they hold in themselves with Kuaidul calling their galaxies sibling galaxies due to them neighboring each other.
In Episode 77, when Yuhi assumes that Phaser put Jointech Nestrider Tank into his deck and Zwijo looks to Phaser Phaser is simply smiling. Despite this Phaser says in Episode 84 that he realized that Kuaidul tricked them the moment Jointech Nestrider Tank got played. This seems rather inconsistent especially when you consider that Phaser didn't seem to immediately do anything or warn anyone, so why is that like that?
Episode 50: Battleship Rush Duel!
In Episode 50, when Yudias and Zwijo's Battleship Rush Duel is going down to the wire, when Yudias's crew calls to the bridge and tells him that they don't have any more pilots to go out and serve as monsters. Yudias tells them it's fine and to send the ships out on auto-pilot. WHY WEREN'T YOU JUST DOING THAT IN THE FIRST PLACE YOU FREAKING HAM?! You are needlessly placing your friends, many of whom are actual children, in mortal peril for no reason.
They are using the Gavil Charger to make the whole Battleship Rush Duel possible in the first place according to Episode 49 and they specified that because of that a pilot would be needed for when a monster is summoned. I would presume that monsters on autopilot are limited in some way or have some risks associated with them which they could ignore in this situation due to them being immediately used for a Tribute Summon.
Episode 51 specified that a monster without a pilot is unable to battle or use effects in a Battleship Rush Duel.
Ah ok. So they knew that Yudias pulling this stunt would likely raise questions about why they needed pilots in the first place, so they made sure to answer them in the following episode.
