I figured I might as well make a Foldletta master post here because this AU eats away at my brain from time to time; technically her name is Suletta Pulone Du Noc, but it's mildly easier to call her Foldletta, Ericht's 13th clone that ended up as a memoryless orphan on Earth after displaying "failures" in her genetic code. Suletta is the only name she remembers, so she starts calling herself that.
Terrorist found family is a very important dynamic that's core to the Foldletta canon. Sophie found Suletta abandoned on the streets and took her into the Fold as sister, eventually introducing her to Norea and forming an ever deeper bond between the three of them.
Foldletta still has the kind and caring personality of Suletta, it's just that she's got a lot of reasons to hate other people (Spacians) and is a lot more direct and ruthless about using violence as a way to keep her family and friends safe.
Another important dynamic is Suletta (Pulone Du Noc) going to Asticassia with Nika and despising Suletta (Mercury) when they first meet for very obvious reasons; having her face, what she believes to be an easier childhood, and a Gundam that doesn't hurt her feeds into Pulone's jealousy, especially because Mercury is capable of being kind and accepting to anyone, no matter if they're Spacian or Earthian, something that Pulone struggles with daily.
Both Sulettas are like the Sun and Moon, and Pulone hates that Mercury is able to still be as shine as much as she does even after going through all sorts of horrible experiences, especially because they are both clones of the same person. She does eventually warm up to Mercury, but still feels vastly inferior to her and ultimately undeserving of her kindess.
After their first meeting, Earth House (and pretty much everyone in Asticassia) starts having to differentiate between Sulettas by using their surnames.
And the last dynamic that's core to this AU is Suletta and Nika, childhood friends separated by circumstances outside of their control but reunited by a chance encounter at a Permet space elevator heading for Asticassia. She takes the Lfrith Fehu along with her in the pretense of "being ready for an operation" so she can enroll in the piloting course and stay together with Nika. Y'know, the things friends do.
In this canon, the Lfrith Fehu is the third Gundam-type mobile suit built alongside the Lfrith Ur and the Lfrith Thorn. It's main design cues were used in the Gundvölva's development, and the unmanned mobile suits had details altered based on the Fehu's combat data obtained in Asticassia's duels. It's distinct weapons are the Tempest Blade, a rifle-saber, and the Beam Repeaters, a pair of automatic hand-held weapons. It's also equiped with the standard-issue Ochs Earth shield on it's right arm, and the Phased Array Cannon like the Ur and Thorn.
The Fehu is colored red, thus making it three times as fast a normal Gundam /j
Hopefully having THIS up leads me to not forgetting details from time to time...
