One of the many speculations going around is that the super mutants in fallout 4 are actually from the master's army and not just a design change, I for one am a believer of this one, what does everyone else think?

There's nothing to really imply that. Marcus was a survivor of the Master's army, and he looks just like any other mutant, albeit more intelligent. I think it's simply a design change.

In previous fallout games it's said that several mutant groups flead east after the master's death. 100 years is more than enough time for even an army to cross that distance.

I know that, but there is still nothing to imply that these mutants are 1st gen MA (Master's Army, not Massachusetts) mutants. Marcus is a MA mutant but looks the same as any mutant and in lore all the west coast mutants looked the same, with varying levels of intelligence. The new look of the Boston mutants may be the result of the local FEV experimentation or just an overall design change.

West coast didn't cause the Behemoths though did it? We have seen they are back.

It's entirely plausible that they are migrated west coast super mutants, or that the Boston super mutants are a conglomeration of those we saw in DC and ones who fled east after The Master's death. I certainly would believe it.

i read or lest say i listen to a video that say that the Super mutants actually are from DC. But we will see.

But actually it will be cool if a combination of both Part of the Master Army the leading group, and the main army is the Dc mutants that are stupid.

I find it reasonable that the more intelligent mutant would gather some FEV from vault 87 to strengthen themselves or even try to cure their sterility, that could also explain why the behemoths in this game are smaller.

You forget that this is Bethesda you're talking about. They try to stay as far away from Black Isle/Interplay/Obsidian canon as they can, hence why they set Fallout 4 before New Vegas. They are not going to intentionally drag MA mutants over to Boston and create some far fetched backstory to explain it. Also, if there are MA mutants in Boston, then they should also have been in DC, since these games are only set about 6 months apart.

At the most, we might see a stray band of intelligent MA mutants, but the majority of these mutants? East Coast FEV strain.

Anyways, your original justification for them being MA mutants is the new design, despite the actual MA mutants looking nothing like the new design.

Current view is the same as why a lot of things have changed visibly, new game with new art assets. Behemoths were ment to be smaller hense the insanely over sized manhole covers and fire hydrants lol. It would make sense for the DC mutants to have left to find more FEV as they had ran out in DC.

Masters army I have issues with them taking attrition and being view negatively by a lot of the world so not sure how many can survive outside of isolated areas really :/

Do we have anything that confirms that this is only 6 months after 3?

Pure Speculation, but I always assumed that given the Pre-War Government's experimentation with FEV that they would have had more than one facility like Mariposa.

The Behemoth's aren't "behemoth sized" and they're green which means they visually have more in common with the west cost strain.

No Behemoths were meant to be towering several stories high. That's not how it was originally intended but it was how they intended them to be when they released Fallout 3.

Possibly but wouldn't that twist be like the one in fallout 3?

The Institute could also have gotten a hold of samples of FEV and begin experimenting.

It's stated that all FEV research was moved to Mariposa and only there but they also seem to be pulling a couple retcons here and there so this isn't out of the question.

It was also stated for the longest time that animal mutations and ghouls were caused by wild FEV released into the air when nukes hit West-Tek.... despite game saying all of it was moved to Mariposa.

Not even the originaly devs kept to that notion.

And repeating what I said later in the thread: Current view is the same as why a lot of things have changed visibly, new game with new art assets. Behemoths were ment to be smaller hense the insanely over sized manhole covers and fire hydrants lol. It would make sense for the DC mutants to have left to find more FEV as they had ran out in DC.

Colourwise new game and new art which could be why weapons and other critters can change e.g. mole rats.

The east coast mutants don't seem intelligent enough to mount an expedition of that scale especially after their home base was raided by the enclave and LW and brotherhood getting better weapons to exterminate them with.

I think you're confusing FEV with radiation, which is the explanation for ghouls and mutated animals no? The only products of FEV as far as I know were wanamingos, deathclaws, super mutants, and centaurs.

If you're referring to what Chris Avellone said I'm pretty sure he said he was wrong and said it was radiation causing ghouls and mutated animals.

I doubt that Bethsada is going to use anymore Lore from the past games. At this point if its not in Fallout 3 or 4 it probably isn't lore.

No, I am referring to how, during the time of Fallout 1, Chris Taylor said all animal and ghoul mutations were caused by wild FEV.

Something Avellone agreed with for some time, until later switching to the only radiation theory that Tim Cain believed in.

Also, deathclaws are not FEV mutants, nothing says they are.

Chris Taylor != original devs

And yeah I was wrong about deathclaws being products of FEV, got confused since both involved genetic engineering.

Scott Campbell, Fallout's first lead designer (the one I suspect came up with the idea of FEV), thought to make wild FEV the cause of mutations in mammals and some insects. I don't know if he had anything to do with ghouls. He first designed the Deathclaw to be a wolverine/brown bear mix "mutated by FEV." Then events transpired, and they replaced the wolverine/bear concept with an abandoned creature model from Planescape Torment. I like Scott's way of looking at things, but he doesn't appear to be the final authority on the lore.

You can read Scott's story of Fallout http://www.nma-fallout.com/article.php?id=60785. HIs comments on FEV are on page 7.

All they've told us is it's the in the same year and a little bit after the Lone Wanderer entered the wasteland
