SCP Foundation

Okay so I kinda had this idea for anomalies "triplets" that were separated at birth, all three have different properties and were basically found by completely different groups. The oldest which at this point I'm just calling scp-xxxx-1 was found by the foundation after shapeshifting into a bat and flying head first into a wall in a very public space or somewhere controlled by the foundation (i haven't decided yet) and then immediately transforming back to a human when he was like five. scp-xxxx-2 is a humanoid figure who has eyes all over his body and while he doesn't actually have wings if he stays against a wall long enough wing like burns will appear on the walls behind him. scp-xxxx-3 is a girl with glowing eyes who seems to be in a semi-permanent state of rage. Her anomalies abilities seem to cater to abnormal strength. All three have regenerative abilities. Idk who raised the last two yet I'm willing to take ideas. Basically, i want the story to revolve around the dramatic tension of these three and where they came from why they're anomalies properties are so different from one another, you know the classic Stuff. Keep in mind this idea is in the incredibly early stages and i am willing to hear any and all feedback!

Okay, but why? This sounds like the premise for a YA novel or maybe some sort of anime or Saturday morning cartoon. All of the triplets sound like cookie-cutter teenage protagonists.

scp-xxxx-3 is a girl with glowing eyes who seems to be in a semi-permanent state of rage.

You'll probably get downvotes for this alone since "rage state" is so overused and so commonly associated with low-quality humanoids that it's become somewhat of a running gag in the community. Also, super strong people being super angry all the time is a very common trope (especially in anime!).

Also, uh… I think you keep mixing up "anomalous" and "anomalies". The first one is an adjective, the second is a noun.

You might be better off with a tale then, since what you have here isn't really solid enough to be an SCP article with the current content. Humanoids are actually among the most difficult types of articles to write successfully; if you're really set on writing one, then first take a look at the humanoid writing guide if you haven't yet. Also, I suggest reading over this essay on common SCP pitfalls to get an idea of what elements to avoid putting in an SCP article.
