Yes. But I hope SCP Foundation won't be like that. Personally, making these beyond comprehendable entities resemble something that is basically an overpowered human is something that the fanbase and it's moderators have been trying to avoid for years. It was the reason why many old SCPs were deleted for being in this cliche mold of a bunch of gary stue characters that fit more in line with Comic Book characters rather then the Lovecraftian mysteries that most SCPs desired to achieve and maintain.
By making most of them fit into this mold, you get rid of that mystery and ruin the fear factor to an extent.
As a comic book reader, I don't mind that stuff, but for the SCP Foundation I expect something a little different and more original. I know people complain about how strict the site is and THEY ARE STRICT. Some really good concepts are thrown away for lacking 'originality' or polishness and that's a bit sad but they do this to prevent stuff from coming in that began plaguing the site back at around 2010 and 2011. A lot of guys were just the same archetypes being used over and over again. Hell, if you ask me, the amount of SCPs they have that are just humanoid reality warpers is already enough. But if they add more then who am I to complain.
Really, it's not like if it's revealed that all these SCPs who existed before looked exactly the same back then as they do now is going to ruin it for me because A. That would be stupid and B. There's no real Canon to the SCP Foundation and you can pretty much follow your own headcannon. Plus, stuff like the Scarlet King being the Father of 682 and SCP-999 isn't even really that widely accepted by the majority oft the community. Does that make it non-canon? Again no, if that's what the reader wants to believen then they can believe it.
For me though, if the author does decide to go into that route and make these SCPs literal Umineko style characters then I'll say that that's a pretty big dissapointment. I'd rather keep it ambigious or talk about them looking different since it was a different plane of Existence they all lived in right? You're telling me Koitern looks exactly the same after his reality shifted? Lol.
