- Clef (the creator) sees Clef (the character) and Kondraki as having an inimical view of each other. However, many Foundation tales written by others depict Clef and Kondraki to be more like Vitriolic Best Buds (without the "best" part, at least). This is horribly subverted in Incident 239-B when Kondraki snaps Clef's neck out of pure rage.
- In the early "lolfoundation" days of the SCP Wiki, Jack Bright was generally portrayed as a Cloudcuckoolander who's fond of pulling wacky pranks for no reason. This characterization has fallen out of favor (although it lives on in "The List Things Dr. Bright Is Not Allowed to Do"), but several interpretations of him remain popular among writers. Is he the Foundation's Greater-Scope Paragon who considers it his duty to help the Foundation avoid the mistakes of the past? Is he an opportunist who only acts in the best interests of his family? Has he undergone severe Sanity Slippage from all of the D-Class personalities he's absorbed? Different tales write him completely differently.
- SCP-682 wants to kill everything because it can't comprehend the world it's in.
- SCP-173 isn't a homicidal statue which loses the ability to move when a human is looking at it. Rather, it's a piece of art that wants people to look at it, and so is content to stay still when someone is looking at it. If someone is present but no one is looking at it, it tries to force that person to look at it, but since it doesn't know its own strength it ends up snapping their necks when it tries. A bit weakened by the fact it will do this to someone looking straight at it when they blink (which would not be helped by moving someone's head around). And due to this page, appropriately titled "crunch". Of course, that is not canon and you can ignore that story.
- The Foundation as a whole. Despite being the literal name of the whole website, they're perhaps the most diversely portrayed of all the GOI. Are they the Weirdness Cops who sometimes have to do unpleasant things in the name of preserving all of humanity, but try to do so with a minimum loss of human life and while retaining what morals they can? Or are they just callous Science Nazis, out to control every item of power they can as much for the sociopathic thrill as anything else, willing to order the cold-blooded slaughter of entire towns on a whim? Articles are written from both viewpoints and a significant number are in between, and there's plenty of arguing over which is the "correct" one.
- Scantron's SCP-001 proposal offers another interpretation: The Foundation is an anomaly itself.
- The Global Occult Coalition. Paranoid and trigger-happy soldiers who destroy what they can't understand, or the real last line of defense who will do things the Foundation can't or won't? (The GOC-focused stories also suggest that the "destroy everything" strategy may not actually be true, and is just how the Foundation chooses to see them.)
- The Church of the Broken God: Are they a group of madmen trying to bring about the apocalypse, or are they just a standard religion that the Foundation have decided to pick on, and will fight back with the fervor of any other group who are persecuted in the same way? And the biggest one of all what if they're right, and the world is screwed up because God is lying broken into pieces and cannot intervene? And the Foundation has responded by, among other things, continually droning God? This is further complicated by the fact that when the Broken God is assembled in an SCP-001 entry, it does NOT seem happy to be here.
- The Serpent's Hand. Are they a moronic and hopelessly naive romantic Animal Wrongs Group for the supernatural who are dabbling in powers far beyond their ken? Or are they an ultimately positive force fighting for the rightful liberation of the supernatural while spreading wisdom and getting rid of the futile desire to preserve "normalcy"? The existence of The Wanderer's Library only helps to further muddy the waters.
- Speaking of which, is the Wanderer's Library just a collection of books? Is it a midpoint between dimensions? Or was it formed in the first reality, and all existence rests on its continued existence?
- SCP-607. Is he a suicidal cat who wants to die and is not aware of his effects of bonding with humans, or is he aware of them and intentionally trying to kill off humans? The photo of him taken by SCP-978 suggests both.
- SCP-447 may do something unimaginably horrible when brought into contact with dead bodies... or it may simply have a memetic effect that makes people think it does.
- SCP-2718 is either the afterlife, a cognitohazard that causes people to irrationally fear a nonexistent agonizing afterlife, or a cognitohazard that causes people who are exposed to it to have an extremely agonizing afterlife. The group of interest page for the Dark Web, which is used by Marshal, Carter, and Dark as an ultra-high-security network, gives another implication that it is not a natural afterlife, but one given to those who will be brought back from the dead in the future.
- The Circus of the Disquieting, post-Fuller: A motley, close-knit group of anomalous outcasts trying their damnedest to keep their show alive, so that they can continue to welcome others like them into their family and avoid the clutches of ominous bogeymen like the Foundation? Or a group of sociopathic freaks who buy anomalous individuals off the black market or outright kidnap them from their families and add them to their collection? The SCPs that have been associated with them tend to show evidence of both sides of the group at times.
