The first three Kiramagers and ground vehicle members in order of rolecall (Red, Yellow and Green) are reminiscent of the "Ready, steady, go!" signal lights of a car race, which the Kiramai Changer's transformation standby sound also tries to enact.
Of course Tametomo's vehicle doesn't match with his profession. There's simply no vehicle that is ubiquitous with gaming that is not immediately delegated to more specific areas in gaming, never mind his profession of competitive gaming. Cars and motorcycles? Racing games. Aircraft? Flight simulation. Watercraft? Naval battle simulations or adventure games by sea travel, etcetera, etcetera, etcetera.
Another reason why Tametomo's vehicle doesn't match his profession is because the he and Shovellow tend to argue and criticize each other unlike the other Mashins who get more easily along with their partners, so there's a sync issue as well.
Unlike most vehicles, the controls on an excavator are a bunch of levers instead of a single steering wheel, bringing to mind joysticks.
Not to mention Juru, who imagined all the Kiramager's mechs, didn't know who Tametomo was so he's likely not much of a gamer. Thus, he has no idea what kind of vehicle would fit best for a gamer.
In episode 2, Tametomo is rather harsh on Juru about his leadership. Of course he would do that. As an aspiring E-sports athlete, Tametomo would be used to working in (if not leading) a cohesive team to rack up wins to get to where he is now. Episode 5 even establishes him as the leader of his own E-sports team.
Jetter is rather kidlike and in a way the youngest of the Core Mashins. He is also the only one of them who transforms into a weapon. So naturally when the other weapon Mashins were revealed, they are even younger and more childlike than him since they are like newborns.
Tametomo turns out to be the perfect choice to take on Reset Button Jamen - as a veteran video gamer, he's clearly familiar with Save Scumming.
There's also a case of Fridge Heartwarming when you realise that Mashin Shovellow would have to trust Tametomo enough to roll out immediately to assist him before anyone else knows about the Jamenshi attack, especially when he's one of the people whose memories will reset every single time.
The Stinger of #15 reveals that Shiguru has whole boxes of that lip balm he always carries with him. He's a TV actor so it's clearly a nod to product endorsements.
Glue Shellgar has an additional skull for a face despite its theme - but the skull and crossbones is also a universal symbol for poisonous material, which glue usually is.
The Kiramagers not suspecting Shuka/Yodonna makes sense due to several reasons:
She is far from the only oddball they met especially compared to Shiguru's obsessive fangirl, Tametomo's gaming opponent who cursed him and of course their own Eccentric Mentor who faked his own death in Episode Zero. At worst they only see her as just an odd anti-social shrine maiden.
Unlike the previous two series, the Kiramagers rarely encountered monsters (Ganglers) or a certain enemy (Wiserue) who could disguise themselves as humans with the only example being the Whack-a-Mole Jamen.
The last reason is that they simply just can't attack "Shuka" since it's their first meeting, they don't know anything about her and weird behavior isn't truly enough to label her as an enemy.
After Sena gets solidified by Mannequin Jamen, Tametomo has to carry her off, and thinks she's gotten heavier. He's the one hefting her off the ground in the "Super Sentai" Stance so he'd be the only one who'd know for sure - also, the process of solidifying in general would normally raise the density of matter.
It is noticeable that the only Mashins with multiple pilots are the one with themed after trains and planes, which are both public transport vehicles. In a way you can say that the pilot is the one on schedule!
The members of Yodonheim are all mask wearers, with the exception of Yodonna. She didn't have to wear a mask, because she is a literal mask for Emperor Yodon's King Incognito mode, something that no one, not even Yodonna found out until late in the series.
Galza's suspicions of Carantula's personality change being due to a clone of him having been destroyed could be right; the clone that was destroyed with Turntable Gomoryu was one who was so dedicated to his takeover plan that he would stake his entire life on it. In other words, the destroyed aspect of Carantula was his evil and dedication to Yodonheim and the invasion itself.
Galza's Not So Above It All moments could be interpreted as his original, pre-brainwashing by Emperor Yodon personality showing through.
Shigeru marrying Sayo in the audio dramas post show might seem like it doesn't have much build up in show but if you notice in episode 32 he's notably the only member of the team who is NOT thrilled with the idea of her marrying that one guy and seems almost disappointed.
There is no real way to dispose of the literal Reset Button that Tametomo ends up with. It's got a failsafe that resets time while restoring itself, and getting a bomb squad to pick it apart will be ultimately futile as one wrong move will literally undo all their progress, and wipe whatever they've learned about it by that time. Wherever it's being kept, it's there forever.
As shown in Episode 18, Jamental can affect just about anything and everyone. Now that Galza has that power, we may be getting a repeat of the Ark in Sentai. This unfortunately comes to fruition in #32, where Galza uses his refined Jamental to corrupt Hakobu.
It is rather terrifying to think what would happen if Tatsuki didn't take the shrunken Mashins with him especially since Yodonna's plan was to capture them in their weakened state.
Numajo's curse seems to take a good long while to activate only to suddenly affect Mabushina right around the time her and Takamichi start to bond again. Seems odd when the person she cursed Oradin was not even alive anymore well he was, but he was effectively comatose at the time but if the curse affects the "King of Crystallia" that would technically be Takamichi himself since he's the current living male of the royal bloodline that wasn't disinherited by betrayal. Meaning it flared up because he and Mabushina became close again and HE triggered the curse causing exactly what he was distancing himself to try to prevent in the first place. To make things worse, the curse targeting the woman the cursed is closest to means that it wouldn't necessarily stop at Mabushina if she died, and next on the list would likely be Sayo, the first Kiramager Takamichi bonded with and one of the closest to him on the team.
