* CanonWelding: Quite a few cases come up, including;

* TookALevelInBadass: To a point;

* YourMagicIsNoGoodHere: Played with to varying degrees;

** Meg is killed off-screen during the raid on Niveus
* DeusExMachina: Apparently Purgatory was created by God to contain the experiments of an Ancient scientist

* ActorAllusion: This storyline contains various allusions to the shared actors of both series, alternating between making the similarities significant and dismissing them as a simple coincidence.
** In two particularly meta examples, Dean 'recognises' an alternate version of Qetesh as Claudia Black, and wonders if he’s talking to [[Series/MacGyver1985 MacGyver]] when he initially hears Jack O’Neill over the phone.
** When Dean first meets Daniel Jackson, he 'recognises' him as Rob ("99 Problems"), Daniel noting that he never expected to hear about a doppelganger of himself on Earth.
** Dean is initially shocked to meet Colonel Steven Caldwell, who is an exact double of Dean's deceased grandfather Samuel Campbell. [[spoiler:When Samuel is resurrected later in the series, it is eventually revealed that Samuel's soul was actually brought back to life in a clone of Colonel Caldwell, as his own body had been dead for too long for anyone to actually resurrect that]].
** Dean is particularly uncomfortable with Todd, as the Wraith evokes memories of Alastair.
** When Harriman discovers Abaddon in the SGC, he initially mistakes her for T.J., until Gabriel appears and forces Abaddon to abandon her meatsuit.
** Looking at footage of Ernest Littlefield's successful trip through the 'gate in 1945, Sam is struck by the similarity between Littlefield and Doctor Carson Beckett.
** When the SGC discover the Men of Letters bunker, they learn from a journal in the bunker that [[spoiler:James Haggerty, one of the Men of Letters, was actually a descended Janus]].
** Despite these other allusions, no reference is made to a similarity between ex-SG-1 member Jonas Quinn and Campbell family member Christian, although this can be justified as nobody who knew Jonas ever meets Christian). For similar reasons, nobody compares Sam Carter to the angel Naomi or Major Evan Lorne to ex-Man of Letters Cuthbert Magnus, as Naomi and Magnus never actually appears in the series.

* RelatedInTheAdaptation: It turns out that Brady is actually one of Cameron Mitchell's cousins, although as Brady has been possessed for so long Mitchell accepts Sam's apologetic explanation that his cousin would be dead even if they exorcise him, later assuring his aunt that Brady wasn't a willing part of the corruption at Niveus that is used to justify its destruction.

* SealedEvilInADuel: The final fate of [[spoiler:Abaddon and Eva, compared by the SGC's deceased allies to the final fate of Anubis and Adria when challenged by Oma and Morgan]].

** Gabriel survives the confrontation with Lucifer (Granted, [[spoiler:he survived that in canon, but this was written before it was known that Gabriel was still alive in the series]])
** Bobby and Rufus are never killed
** Angels such as Rachel survive as Gabriel's survival allows him to take an opposing stance to Raphael and thus prevent the angelic civil war.

** The SGC also take precautions against the supernatural, starting when Gabriel creates a devil’s trap made of naquadah in the conference room, with the staff establishing more standard traps across all possible entrances a demon might use; Sergeant Harriman [[spoiler:even attempts an exorcism when first faced with Abaddon, suggesting that the SGC are at least trying to teach their personnel how to protect themselves against demons even if Harriman couldn't recall the exorcism on his own]].

* JerkassRealisation: Even after Gabriel returns to Heaven, it takes [[spoiler:witnessing a demon invasion of an Icarus-class planet escalate to the point where the only chance of victory is Gabriel dialling a black hole and dropping the Stargate in the sun for Raphael to realise the full consequences of his desire to still trigger the Apocalypse]].

The '''''Tok’ra Apocalypse''''' series by [[https://www.fanfiction.net/u/166193/San-Antonio-Rose San Antonio Rose]] is a significant crossover between the ''[[Franchise/StargateVerse Stargate]]'' franchise and ''Series/{{Supernatural}}''. Starting when Dean and Sam discovered the hotel attended by various gods, this series puts a spin on those events by establishing that the ‘convention’ was attended by a mixture of true gods and Goa’uld from a parallel universe, who had captured two Asgard in the process. Having become Tok’ra to better infiltrate the meeting before Lucifer arrives, Dean and Sam find themselves with a whole new set of allies as the SGC join them in their goal to stop the Apocalypse, leading to such events as the Winchesters relocating to Atlantis, the re-establishment of the Men of Letters, and a war that brings together the mythologies of both series in a very well thought-out manner.

!!''Tok’ra Apocalypse'' contains examples of:

* BabiesEverAfter: [[spoiler:Josie becomes pregnant with Henry’s child, with even Dean coming to appreciate the new family being formed despite being simultaneously freaked out at the idea that he and Sam will have an uncle who’s younger than them]].

* ButForMeItWasTuesday: Time travel is still a strange situation, but the SGC are fairly nonchalant about that as an explanation for Henry Winchester’s presence after he appears in Dean and Sam’s room in the SGC through their closet.

** The Goa’uld tend to impersonate dead true gods, as observed by Gabriel
** Ernest Littlefield was a member of the Men of Letters
** The Men of Letters Legacies’ members were linked to the Ancients

** [[spoiler:Crowley]] is killed by [[spoiler:Gabriel and Teal’c]] after ‘helping’ the Winchesters capture Brady

** On a more drastic note, the invasion of a potential Icarus-style planet [[spoiler:is only thwarted when Gabriel orders the SGC’s allies to evacuate the planet before dialling a Stargate near a black hole and dropping the active gate into the sun]].

* ExactWords: When Crowley wonders if ‘Murray’ is a hunter, Teal’c states that he has spent many years destroying false gods, and has hunted Wraith and other creatures that threatened Earth; all true, but not in the sense that Crowley would expect

* GenderSwap: Downplayed; while [[spoiler:stopping a demon-possessed scientist travelling to Destiny, Bobby Singer triggers the stone and arrives on Destiny in the body of Chloe Armstrong, but aside from TJ musing that Chloe is ‘probably freaking out right now’ and Bobby warning the boys not to talk about it once he gets back to his body, his visit to Destiny is focused instead on warning the Destiny crew how to protect themselves from potential demonic incursion]].

* IgnorantOfTheirOwnIgnorance: Introducing the SGC to the Winchesters and the supernatural to the SGC puts both of their respective enemies in this kind of situation, as even [[spoiler:Abaddon]] only recognises the Stargate as the chappa’ai without knowing what the SGC have achieved, while the Genii are caught off guard when an angel calls Ladon out for condoning the plan to essentially ‘exile’ Atlantis from the Coalition.
* JumpedAtTheCall: Dean still calls Henry out on travelling through time and abandoning his son, but accepts Henry’s counter-argument that it was do that or get killed by Abaddon

* NoodleIncident: Gabriel muses that the SGC missed Lucifer’s release because they were busy trying to get Atlantis back to Pegasus

** Downplayed for Sam, as his subtle telepathic abilities give him a connection to Torren that he uses to reassure the boy when Teyla can’t do it herself

** As far as the general population is concerned, Sam and Dean are ‘put on the bus’ after the Apocalypse, but in reality they were ‘just’ [[spoiler:relocated to Atlantis]].

* SealedEvilInADuel: The final fate of [[spoiler:Abaddon and Eva, compared by the SGC’s deceased allies to the final fate of Anubis and Adria when challenged by Oma and Morgan]].
* ShipTease: It is all but explicitly stated that Sam Carter and Jack O’Neill are in a relationship, and it is just slightly more explicit that John Sheppard and Teyla are in the same situation.
* ShipperOnDeck: Dishon and Sam each express approval of Lisa’s relationship with Dean, [[spoiler:which culminates in Lisa becoming Tok’ra herself so that she and her symbiote can marry Dean and Dishon to justify their continued presence in Atlantis]].

** Angels such as Rachel survive as Gabriel’s survival allows him to take an opposing stance to Raphael and thus prevent the angelic civil war.
** [[spoiler:Henry Winchester and Josie Mills survive Abaddon’s attack on the Men of Letters to form a new division affiliated with the SGC and including Bobby and Rufus as associates if not full members]].

* TechnicalPacifist: Dean encourages the Nox to take a more active role against demons by arguing that they can use wards and exorcisms, thus preventing them violating their rules against violence as they aren’t actually killing anyone.

** Dean and Sam were always tough, but making them Tok’ra gives them access to alien knowledge and two very useful and loyal allies, to say nothing of the respect and assistance of the SGC.

* WhatTheHellHero: Landry muses that the SGC may receive this from the IOA for revealing the secrets of the program to a couple of wanted killers and a man who thinks he’s an archangel (the fact that the killers are supernatural hunters and the man really is an archangel won’t be enough to convince the IOA without better evidence).

** With the ‘aid’ (both known and unknown) of Gabriel, Crowley, and the demon inhabiting Brady, the SGC are able to use the Odyssey’s sensors to identify angels, demons (and the differing ‘ranks’ of relevant demons), and even the Horsemen

** For obvious reasons, nobody at the SGC is willing to risk finding out what would happen if a demon-possessed human tried to use a communication stone to contact Destiny
