These are The Gems, a group a sea angels all born from The Devil, who went insane trying to protect them from Cipher.

This is The Devil:

She is cruel and rash and highly reactive. She tries to hurt people before they hurt her.

With her children she is protective and tries her best to be still and loving, although she may falter at times.

She is a product of her situation of being a henchmaniac of Cipher's while she had these children.

They're all hers, she's the only parent.

She and her children have died dozens of times. The Devil restarts the timeline and tries to survive with them all again, effectively trapping herself and her children in a timeloop.

The children love their mama and were forced to evolve from the harsh conditions they had gone through ranging from not having enough food to Cipher finding out about them and toying with them until they died one by one.

Azurite, the one with the red heart, tends to be the first to die. She is the most colorful and playful one, mistaking Cipher as a friend.

In the "best" timeline, Azurite is the only Gem to pass away. This, of course, isn't good enough for The Devil at all but The Axolotl tries to convince her to not sacrifice what goodness she was able to promise her other children.

The Devil met The Axolotl after the Time Police raided the nightmare realm and Time Baby killed her.

The Oracle prayed to Xolotl bc the children didnt have their mother and The Oracle prayed for guidance. Xolotl took them in along with The Devil's soul to try and help rehabilitate them iin the Theraprism.

Theres many more details but this is long as it is.

Bill's parents didn't regularly visit family, but Euler was the one relative they saw most often. He was the first person to snap out of the "haha it sure is funny how Bill can guess when somebody's about to knock on the door" rationalizations to realize that Bill really could see things no one else did.

And since Bill's parents are sort of disasters who think starting a cult is a great get-rich-quick scheme, Euler was one of the most emotionally stable role models in Bill's life. It sure is a good thing that Euler was a constant presence and nothing happened to him during Bill's tender formative years!

"But wait," you say, "you told us that Bill got his shape and slit pupil from his dad. But wouldn't that mean he got genes for a square? And how could he have gotten a slit pupil if that wasn't a genetic trait, but a consequence of an eyeball splitting in half?"

Triangles and slit pupils don't run in Euclid's side of the family. But squares and twins do.

I imagine Bill's twin obsession is rooted in something close to home.

"So Steve exists in your headcanon—?" No. He's a stillbirth his parents pretend doesn't exist. He's a crime Bill committed before he was born. He's the imaginary phantom Bill's parents are searching for when they look at Bill—starting fires, hallucinating, spitting up his medicine—and wonder what he'd be like if he was different. He's a symbol representing a source of unconditional love and support that Bill deserved and needed, but never had. Steve's all those things—but he doesn't and never has existed.

And there at last is my Euclid headcanons post. If y'all are interested & didn't see it, here's my Scalene headcanons post! And some headcanons about shape twins that still basically work post-TBOB, we just know now that Euclideans don't need a line and a polygon to reproduce.

(95% of my headcanons about Bill's dad & uncle are pre-TBOB. The only difference is that I originally designed Euclid & Euler as green trapezoids that had split from a hexagon. Trapezoids so that Bill and his dad could do this, green so that Bill's dad could be the original color Bill was designed as before the Gravity Falls crew made him yellow & so that his family could be money-colored: gold-colored Bill & mom, dollar-bill-colored dad.)
