The Bionis and Mechonis are standing in an infinitely large ocean. The sun still rises and sets. Where does the sun go at night?
Looking at the sunset from an open area, like the Bionis Leg, reveals that the sun doesn't go down the horizon, it vanishes before reaching it. One of the heart-to-hearts reveals that the "stars" in the night sky are actually just ether; who's to say the Sun and the Moon aren't just ether that looks like the real deal too? This would especially make sense when the true nature of Zanza and Meyneth is taken into account. They made it so day and night looked like what it was back on Earth, but without the "other celestial bodies out there" part.
Why do the Machina have breasts? And why do theybounce? What sort of metal does that?
Because they're beings made in the image of a human, and humans have breasts.
Why did Dickson shoot Shulk? I understand all the god stuff but why did he do this? Was it necessary to trigger the transformation? Or was it purely an asshole move based on the decision Shulk was coming to?
Both it seems.
Not so much a complaint as an observation- does anyone else see the symbol of the Testaments on the back of Alvis's jacket? I can't shake the feeling that it's the exact same symbol, but heck if I can make any connection between Alvis and the Testaments- even speaking as someone who believes all the Xeno games are on the same timeline.
After the Mechonis Core, there is a very real concern about Fiora running out of power and dying before the quest's end, as her cardiopulmonary systems were being provided power by Meyneth's Monado. The first thing we see after Junks lands at Colony 6 is Fiora presenting the first Replica Monado to a comatose Shulk. Would it have been so unreasonable to say to Vanea, "Hey, think you could make me one of those? Sorta triangular, about, say, this size?" I know that the problem is solved by the epilogue, but as a quick fix to take some of the stress off of Fiora's, Dunban's, Melia's and... well, everyone else who spotted the issue with her body straight away's mind. Additionally, as the issue at hand would have been her machina body running out of power, couldn't you conceivably have used one of the two potential solutions to extend Neonik's life for Fiora?
It's possible that none of these would have worked. The Replica Monados might not have been able to supply the same energy that the genuine ones can, and Fiora's condition, and possibly her architecture, are considerably different from Neonik's.
(Original Poster) I can accept that the replicas weren't as powerful as the real deals, but at their base they at least had to have some means of either storing or converting ether energy out of the air to provide the energy blade the weapon used. As to Fiora's architecture, take this into account - on first meeting her, Linada, the machina doctor, mistook this strange robotic woman for one of her people, not realizing that she was a Face unit until the party actually mentions it. While their problems weren't identical (Neonik was dying from being damn near 10000 years old, Fiora is dying because Meyneth isn't powering her heart and lungs anymore), they boiled down to something very similar - their power systems were failing, and a shot of energy from an old Machina unit was enough to repower Neonik for another 20 years. Of course, if Fiora's power really couldn't be restored, it makes the usage of Final Cross REALLY irresponsible post-Mechonis Core, since the whole thing shakes out to "Massive blast of Monado power hits stuff".
Sure, but given that no other Machina have Monados powering them, it's quite possible that Fiora's power system is a unique technology and incompatible with other power sources.
(Original Poster) Fair point. That said, since Vanea was the one who originally put together the Fiora/Meyneth/Face Nemesis combo platter, she would probably have been the one most qualified to put together a stopgap system to keep the one remaining piece (Fiora) from terminally powering down. Also, while Gadolt doesn't survive long enough for this to matter, would all pilots of Face units, separated from their respective mecha, eventually succumb to cardiovascular failure, or is Fiora's problem entirely unique? I seem to recall that even with Meyneth on board, early on you still needed to scavenge parts from a wrecked Mechon (piezoelectrical unit, if memory serves) to prevent a complete system failure of Fiora immediately following your arrival at Junks. Then again, Fiora did suffer some rather critical... system damage in the process of getting taken in the first place (Impaled with Extreme Prejudice - not good for one's internal organs), and Linada did express some surprise to find that most of Fiora's innards simply weren't there anymore. So it could well be that her imminent shutdown (and lack of necessity to eat) was more a function of "Metal Face stabbed me with claws as long as I am tall" than "Meyneth isn't providing me limitless free energy". I know that Vanea eventually points out that some modification has to be done to a Homs to make a Face unit work, but maybe Fiora's modifications were a bit more extreme out of necessity, rather than simply to make her invincible to standard Monado damage.
If some High Entia have been interbreeding with Homs up to the present day, but most Homs speak of them as though they were long extinct or a fairy tale, is there an explanation for this that doesn't involve kidnapping?
Well, it's established that there used to be more Homs settlements before the war with the Mechon. Could be that some of the old colonies that were destroyed were closer to High Entia lands.
So in Satorl Marsh, Dickson has a line about how he feels bad about deceiving Shulk and co. Yet as soon as he makes his treachery known, he immediately switches to his true persona of a smug, unrepentant Jerk Ass of near Card-Carrying Villain levels who flat-out gloats about deceiving the heroes, making that line seem rather out of character in hindsight. So... What was the point? Was it just a narrative cheat to make Dickson seem like he might not be that bad despite obviously being up to something? Or an attempt at Hidden Depths that was ultimately left unexplored?
