Mobile Suit Gundam/WMG

Newtypes are metahumans.
The notion that humans would evolve into Newtypes by moving into space is thoroughly disputed, and even outright dismissed by Tomino. Besides this, we see quite a few Earth-born Newtypes. If one looks at Gundam X, we see Newtypes whose powers are triggered by near-death experiences, as well as This would also explain why people with abilities like mental communication (the Frost brothers) and healing powers (Queen Maria) are considered Newtypes even when they don't match up with the usual set of powers that a majority of Newtypes possess. A similar related issue of debate is what constitutes a true Newtype. The obvious definition of "people that have Newtype reactions" is only one possible definition, where another (as explained to this troper by a friend) are humans who have adapted to exist peacefully and in their element in space. This interpretation actually cites as the quintessential Newtype not any of the normal pilots, but Bright Noa and his wife Mirai.
 * Tomino also went out of his way to establish that they WERE in fact, Evolved Humans in the novelization of the original series. Furthermore, it's Char's whole thing that he believes mankind can become better by being forced into space.
 * Tomino did originally concieve Newtypes as evolved humans, but later grew disenchanted with this perception. The idea of Newtypes becomes less important the later a series is made, culminating in Tomino's Turn A Gundam having no Newtypes at all.

Newtypes are caused by minovsky particles.
Specifically, minovsky reactors give off a kind of radiation that affects the brain and reproductive organs, and has more pronounced effects the younger the exposed person is. Amuro, a teenager going through puberty, initially had no newtype tendencies, but after spending puberty almost constantly sitting on top of an extremely powerful minovsky reactor he became one of the most powerful newtypes in gundam. While Char spent more time piloting than Amuro, he didn't become a pilot until he was almost completely done puberty, and therefore was not affected to the same degree.
 * This may also justify why the best pilots in the UC timeline are teenagers who spend a lot of time around heavy machinery.
 * That's why Newtypes are from space. All that heavy equipment and high-energy radiation. The Earth-born Newtypes have all lived through the conflicts, where radiation was flying everywhere.
 * A similar idea is cannon in 00 Gundam. Heavy exposure to GN particles transforms humans into Innovators.

The Movies are canon, the TV series is a drama created sometime after the war.
Various exploits were added to the White Base's 5 month journey to fill up more episodes, some scenes were changed or made up by the writers, various additional vehicles that the crew never actually encountered during the war were added, such as the Big Roe, as well as incomplete prototypes that never even saw action such as the Gyan & Zakrello to make things more interesting & a few completely made up ones like the G-Fighter were added for Merchandise Driven reasons. The Gundam never participated in Operation Odessa, as it was tied up fighting the Black Trinary at the time, but did both in the TV show because the writers figured they had to include an important battle like that. Commandant Walkeine never imprisoned the crew, that part was added because he had joined the Titans after the war & as such the writers wanted to paint him as a villain.
 * Problem with this is that Walkeine did not join the Titans, he died in the TV series as a good guy, and in the Gihren Ambition games the What If he didn't die, he does not (Unlike certain other characters) defect to the Titans. He's also an awesome ship commander.

Japan took over South America sometime prior to the formation of the Earth Federation.
There are a few things which hint at this. Ryu & Kai both have Japanese-sounding names, but hail from Argentina & Puerto Rico respectively. Also the EFA HQ in South America has the oddly Japanese-sounding name of Jaburo. This may have been due to the massive worldwide energy crisis which preceeded the EF's formation, with Japan abandoning its post-WWII peace constitution out of desperation due to the small island chain's resources being insufficient to support its massive population density. They didn't dare go after continental Asia or North America again after what happened last time, so they took on South America instead.
 * Of course, in Real Life there is a not-insignificant number of Japanese in South America.
 * Jaburo is a real place in Brazil.

Miharu's little sister grows up to be Four Murasame.
According to the MMSV book her brother became Three Murasame & piloted the Prototype Psycho Gundam. It would make sense that if the two of them were brought in together she would become the next number.

Judau Ashta is somehow a direct relative to Dozle Zabi
Compare Dozle's last stand atop the Big Zam with a machine gun, summoning a tremendous ghastly phantom behind him to Judau's phantom thing when Haman ends up shooting Leina. Both instances caused the respective Newtype they were facing to display an Oh Crap look for the ages and both involved protecting a little girl, Dozle fighting for his family and Minerva and Judau furious at Haman for attacking Leina.

Char Aznable is a French singer.
Names the Same.
 * Only Charles Aznavour could have produced a theme like Gallant Char.
 * The final battle of Char’s Counterattack has Char Aznable blasted to the distant past eventually taking the persona of Charles Aznavour.
 * Charles Aznavour lives long enough to become the legendary Mobile Suit ace Char Aznable.
 * Char Aznable is Charles Aznavour reincarnated.

Martin Prochnow is Ryu Jose's father
Remember Ryu, one of Amuro's crewmates on White Base, who sacrificed himself to save Amuro's life? Remember how well-built he was, and the sound of his voice? Now, take a look at Captain Martin Prochnow of the Jotunheim. Well-built guy, and a rather unique voice as well. It can't be a coincidence. Maybe Ryu was born on Side 3, but his mother had a falling out with his father and took him to Earth, where he lived under his mother's name, Jose. Then he later joined the Federation, signing up just before the One Year War began. Were Martin to know about the fate of his son...

Ramba Ral had Alzheimer's disease
In the middle of a battle, Ramba Ral forgot to fight.

Gouf is actually an inferior Mobile Suit compared to Zakus
Gouf pilots like Norris Packard and Ramba Ral are so awesome it doesn’t actually matter that they’re in an inferior mecha. If the Gouf design was so superior then why wasn’t it mass-produced by Zeon?
 * It was. Mass-produced units were deployed against White Base (Allowing Amuro to rake up a healthy number of kills there) and later participated in the Jaburo offensive. The problem was that Gouf was a ground-combat-based design and after Jaburo the Zeon retreated back into space.

Despite Ramba Ral’s contrary claims the Gouf is a Zaku
There really isn’t much of a difference.

This is no Zaku, boy! No Zaku!
That thing's got more armor and power than a Zaku - it's completely different! It’s like a Zaku, but completely different! In﻿ Soviet Russia, this is a Zaku, boy. This is no Shout Out, boy! This is no Flag, boy! This is no Memetic Mutation, Boy!
 * No Zaku!
