Editing Primaris Space Marines (section)

==Initial /tg/ Concerns, and how things in 9E played out==
* There was an initial concern amongst the usual circles of what would become to all the "standard" Astartes equipment with the advent of the Primaris. As the lore advanced and evolved, the answer eventually became: they'll still be used until either all Firstborn (old-school Marines) died out, or crossed the Rubicon Primaris. As it is, there's so far no crossover in equipment between Firstborn and Primaris, so Chapters will continue using, say, Terminator armor until there's no one left to fit in them.
**As for Termies, GW has essentially given up on replacing such an iconic unit and said “ah fuck it, everyone can wear it.” This same train of thought is also why Primaris marines are now suddenly able to fit into firstborn transports like [[Land Raider]]s and [[Drop Pod]]s.

* Primaris marines were made from all extant Loyalist genelines [[Traitor Legion Loyalists|(and possibly some traitor genelines as well)]], and thanks to the material made available to [[Belisarius Cawl]] through the Sangprimus Portum, show little to none of the idiosyncrasies that usually mark the bloodlines of [[Space Wolves|Russ]], [[Blood Angels|Sanguinius]], or [[Thousand Sons|other]] [[Luna Wolves|Problematic]] [[Word Bearers|Genelines]]. Not only that, but according to an (admittedly biased) in-universe source, there's only a .001% chance of genetic deviation per generation, which means that the Primaris genestock are incredibly stable as well. Interestingly, thanks to Cawl's work Chapters that have lost organs through the centuries (like the [[Imperial Fists]]) or have malfunctioning organs (like the [[Raven Guard]]) all of a sudden have a complete set of organs thanks to the influx of new Primaris blood.
** What prior edits to this very article seem to have forgotten is that, for all the improvements that Cawl made on the Primarch gene samples to create the Primaris, he ''specifically'' didn't tamper with traits that seemed already inherent in them (and the Cawl Inferior actually states this outright to Guilliman). What he DID do was ensure stability, which makes things that used to be outright impossible -- like the [[Space Wolves]] being able to have Successors -- to be an actual possibility now. Say what you want about the [[Wolfspear]] still having Wulfren tendencies, ''none'' of them has actually turned into a raving [[Furry]]. Indeed, the Wolfspear is shown to be ''thriving'', despite recruiting Astartes from planets that aren't Fenris.
** Same thing for the Primaris Blood Angels still having the Black Rage, as it's not a genetic disorder, but a ''psychic'' malady. Instead, Cawl seems to have toned down on the negative effects of the Red Thirst instead (as this is the "feature" of that gene line).

* Primaris being larger turned out to be a non-issue, both in lore and in rules, as a Primaris marine is capable of moving as fast (if not reacting ''faster'') as a Firstborn, and also capable of using the same sorts of cover a regular Marine can use.

* Cawl’s work isn’t always perfect, and his arrogance gives him a tendency to overreach. This is exemplified in Alpha Primus, the first and prototype Primaris Marine, who seems to be Cawl’s heretical attempt at making his own Primarch (see the Magnificat, above), and has since been relegated to being the archmagos' bodyguard. He’s so giant that he towers over even other Primaris, is an extremely powerful psyker, and is described as “more gifted” than any other Astartes. He also exists in a constant state of pain, both physical and mental, which gives him a personality that Marvin the Paranoid Android would find tedious, and he’s nominally considered a failure. He even has a stitched-together face to reinforce the parallels with Frankenstein’s Monster (the original, highly intelligent but extremely emo one). Whether the Primaris as a whole will eventually turn out to be a more subtle example of Cawl’s overreach is an open question. Most Primaris dismiss this concern as they believe Guilliman would immediately execute Cawl if he attempted to create a Primarch and that even Cawl isn't willing to push his luck that far.
** In case someone wants to ask if there's something he can't just make better, 10th Edition revealed one: [[Terminator |Terminator Armor]]. Apparently it's just too good that he can't do anything with it aside from retrofit it to make it wearable for Primaris Marines. So we assume that first company Primaris are either Terminators or [[Bladeguard Veteran|Bladeguard Veterans]].

* Many sources point to the Primaris being seen as greenhorns by many of their adopted Chapters, but this issue has also been ironed over by time. Even the most recalcitrant Chapter like the [[Dark Angels]], while not exactly won over initially, now see that the Primaris have their strategic and tactical uses, and its only really the Chapters' traditions that keep them from being fully integrated. While it will probably still be a few more centuries before the number of Primaris that become, say, part of the [[Deathwing]], increase to more than a handful, as shown again by the Wolfspear the Primaris have more than proved their worth by this point.

* Chaos will be interested in the Primaris Marines. The [[Chaos Gods]] are not happy with the existence of the Primaris Marines, and are creating some warp charged warriors to counter them (likely along the lines of the Greater Possessed). [[Fabius Bile|Fabulous Bill]] became obsessed with "perfecting" the Primaris Marines from the moment he first encountered them and has already begun trying to kidnap Primaris Marines for dissection. They've supposedly been made resistant to Chaos influence, but "resistant" doesn't mean "immune" by a long shot, since they still have a soul. In fact a [[Noxious Blightbringer]] is able to affect them in Dark Imperium, successfully hurting and trying to get them to turn. And come to think of it, the cover image of 8th Edition does seem to partially show a [[Plague Marine]] in Tacitus armor...
**The discovery that Cawl wanted to use Traitor Legion gene-seed as well as the gene-seed of the missing legions to make Primaris Marines doesn't help the matter; Guilliman refused to let him do so, but he has a feeling Cawl will try it anyway with predictable results.
*** Cawl claims that it was only due to the influence of the traitorous Primarchs that their Legions fell to Chaos. [[Traitor Legion Loyalists|While this may be true]], attempting to test that theory was something that Guilliman expressly forbade...not that Cawl listened to that anyway.
*** The reasons as to why the Lost Legions were purged so thoroughly were apparently so unthinkably horrible (so much that even after his rebellion had begun, Horus was still unwilling to break the vow he made to never speak of the Missing Primarchs) that Cawl trying to use their DNA might bite him in the ass even harder than for using gene-seed from the Traitor Primarchs. (Though it is worth nothing that the Lost Legions were not executed along their Primarchs but instead given over to the Ultramarines and Imperial Fists.)

* While barely explored in-universe so far, the various alien races in the setting may also take exception to or dangerous interest in the Primaris Marines. While most are much less interested in genetic modification, we've already had:
** [[Urien Rakarth]] has expressed interest in them in spite of what he calls Guilliman's "lack of imagination", and has requested his [[Haemonculus|Haemonculi]] bring as many to him as possible; more unnervingly, he has expressed that he will be saving his best oubliette for the Primarch if he ever wished to "learn from the master". Given the upheavals in Commorragh with the Dysjunction, the birth of Ynnead and Vect becoming a Living Muse, there are other parties among the Dark Eldar who'd likely take an interest in Primaris marines for more "material".
** It would be equally unsurprising if [[Illuminor Szeras|a certain spider-legged robot mad scientist]] also wanted to collect a few Primaris specimens. In the latest lore he's becoming a more active player on the galactic stage between creating the Null Sector and signing on with the newly returned Silent King, and Primaris marines could be considered prime targets for bio-transference.
** At least one Ork Mekboy came up with the idea of creating more potent bullets to deal with "da big beakies". As of the Ork codex, Mad Dok Grotsnik (You know, the guy who CREATED GHAZGHKULL) has kidnapped a bunch of Silver Skulls Primaris marines for unknown purposes. So that bodes well.
** The Tyranids, being what they are, will definitely incorporate the DNA of Primaris marines into their makeup if they can get any into the digestion pools. [[Tyrant Guard|This wouldn't be the first time either]]...
**The Tau's Fifth Sphere Expansion has run into Primaris Marines during the course of pushing into the Imperium. Naturally, the blueberries are trying to adapt their previous anti-Marine strategies and armaments to deal with the new Gue'la supersoliders.
* People keep on pointing to the [[Brazen Drakes]] example of how Primaris may become Renegades, but miss the point that a) the Chapter went rogue before the Torchbearer Fleet got to their homeworld and b) the Custodes were pricks for deciding, then and there, that just because the Chapter they were bringing the Greyshields to went renegade, that the Primaris that hadn't even officially joined the Chapter except in name were ALSO Renegades. As of ''War of the Spider'' subsequently showed, karma waved hello to that Custodes contingent VERY quickly.
