The Sagittarius subsystem is a collective of introvects from Marvel, broken into various smaller subsystems. They also have a collective Tumblr blog separate from the rest of the system.
Most members of Sagittarius do not consider themselves fictives, but rather to have been transported here from alternate realities which are superficially similar to their fictionalized equivalents in ours, which they designate as Earth-1218, a world in which the heroes of other realities are considered fictional.
A collective of Spider-Totems from across the multiverse. All of them experience a phenomenon they refer to as "equilibrium", which causes them to perceive themselves as always being upright regardless of orientation.
In system: An introvect of Gwen Stacy (Earth-65). A host of the system as a whole and one of our most individualistic members, who regularly encourages the others to develop their own interests and hobbies; she also has her own Tumblr blog separate from the rest of the system. The first member of the subsystem to arrive, and the first in the full system to reject the term "fictive". Currently dating Illyana and Kitty.
Pre-system: The Spider-Woman of Earth-65C, who was bitten by a genetically engineered spider which granted her powers. Falsely branded a criminal for the death of her best friend Peter Parker, and would later become an integral player in various multiversal conflicts. Mostly similar to the comics' portrayal of her Earth-65A counterpart, but the splinter universe she comes from has various differences, including her being trans. Avatar credit: Unknown
In system: An introvect of Jessica Drew (Earth-1610). The third member of the subsystem to arrive, as well as the one who adjusted the most quickly to her new existence due to previous experiences with similar sudden changes in identity. Sees herself as somewhat of an older sister to the other subsystem members. Currently dating Cindy.
Pre-system: A genetically modified female clone of Earth-1610's Peter Parker, who retained his memories and abilities. While she initially struggled with her identity due to her memories of life as Peter, she eventually grew into her new identity as Jessica Drew, her universe's Spider-Woman, and would later mentor Miles Morales after Peter's death.

In system: An introvect of Peni Parker (Earth-14512). Her "equilibrium" isn't quite as strong as the others, and she finds it slightly disorienting without her suit. A bit younger than most of the system at roughly 16y/o. Tries not to be around for meals, as she's a vegetarian and doesn't want to interfere with our dietary tendencies. Has her own Tumblr blog separate from the rest of the system, though she's rarely around to post much.
Pre-system: A young girl from Earth-14512 who followed in her late father's footsteps as the protector of New York, forming a psychic link with the spider that controlled his SP//dr mech suit and later becoming an integral player in various multiversal conflicts.

In system: An introvect of Cindy Moon (Earth-616). The first member of the system to consider herself a fan of K-pop in general outside of a handful of specific songs. Currently dating Jessica.
Pre-system: After being bitten by the same irradiated spider that bit Peter Parker, Cindy was taken in by an elderly Spider-Totem named Ezekiel Sims and trained to use her powers. When Sims realized that the totemic vampire Morlun was on the move, he hid Cindy in a bunker to keep her safe, where she reluctantly but willingly remained until she was freed by Parker 13 years later, becaming the hero Silk.

In system: An introvect of Charlotte "Charlie" Webber (Earth-20023). Arrived after a long and stressful road trip, and generally very glad to be less severely disabled despite some familiar symptoms.
Pre-system: During her early years of high school, Charlotte Webber was bitten by a radioactive spider, becoming the hero Sun Spider. Due to her hEDS, she was an ambulatory wheelchair user in civilian life, and built her webshooters into a pair of crutches, utilizing her newfound powers alongside the additional flexibility caused by her condition to protect the city alongside fellow heroes such as Histamina, who she was initially unaware was her crush Aster.

An introvect of Moon Knight, a DID system who were killed after rebelling against an overly sadistic mercenary leader and revived as the Fist of Khonshu, the Egyptian god of the moon and protector of night travelers.
The host of the system, an Czech-American Jewish ex-CIA mercenary who developed DID after being attacked by a Nazi serial killer who pretended to be a friend of his rabbi father. Avatar credit: Marvel Comics
One of the first alters in the system along with Jake, who used his financial and business acumen to strike it rich off investments manipulated by Marc's mercenary activities. Avatar credit: Marvel Comics
One of the first alters in the system along with Steven, who used his connections as a New York cab driver for information gathering to support Moon Knight's vigilantism. Avatar credit: Marvel Comics
A collective of various X-Men. Originally not considered a subsystem, but grouped together when multiple subsystems of Marvel introvects were consolidated into one subsystem.
In system: An introvect of Rogue from Marvel Comics. Much like Yelena, her accent being infectious played a large part in her arrival in the system, as well as the influx of attention towards her parallel due to being added to Marvel Rivals.
Pre-system: A young mutant who ran away from her family and was taken in by Mystique and Destiny as foster mothers, becoming a member of the former's Brotherhood of Evil Mutants and eventually leaving them to join the X-Men. Unable to control her powers for the majority of her history, she was forced to avoid touching others at all cost in order to avoid draining their energy, though when faced with a combat situation this power became a major asset, allowing her to temporarily absorb the powers and even memories of her adversaries.

In system: An introvect of Illyana Rasputina from Marvel Comics. Enjoys playing as herself in Marvel Rivals. Speaks with a heavy Russian accent, and is frequently frustrated by feeling like she should know how to say something in Russian but we lack the collective knowledge to do so, as well as sprinkling small expressions in Russian or quotes from her source into conversations. Currently dating Gwen and Kitty.
Pre-system: The younger sister of the X-Men's Colossus, Illyana was kidnapped by the demon Belasco at a young age, to be tortured and later trained as his apprentice in Limbo. After years, she finally overthrew Belasco and returned to Earth, creating the Soulsword from her own life force and later returning to become Limbo's queen and Sorcerer Supreme.

Illyana's darker other half. While we know it exists as part of the system, it does not appear to have an identifiable "personhood" of its own, and has only been seen as a sort of overlay on top of Illyana's own personality, notably showing up most often when she is annoyed or in pain.

In system: An introvect of Kitty Pryde from Marvel Comics.
Pre-system: A young member of the X-Men with the ability to change her density at will, allowing her to phase through walls, walk in midair, or allow physical attacks to pass through her harmlessly. Longtime friend and roommate to Illyana, due to being roughly the same age after Illyana's accelerated aging from time dilation in Limbo. Currently dating Illyana and Gwen.

An introvect of Aurora, a member of the Canadian team Alpha Flight who developed DID due to their abuse in the Catholic orphanage they grew up in. Originally didn't get along very well, but are doing their best to treat coming here as a fresh start and build a better relationship.
The host of the system, and the holder of most of their religious trauma. Stern, introverted, and strict. Avatar credit: Marvel Comics
The member of the system who held control of their mutant powers. Extroverted and upbeat. Avatar credit: Marvel Comics
In system: A fictive of Yelena Belova from the Marvel Cinematic Universe. Showed up the same night we watched Thunderbolts* for the first time, in large part due to her accent sticking in our head.
In source: A child assassin trained as a Widow by the Red Room, Yelena was assigned as part of a cover family for Alexei Shostakov (Red Guardian) and Melina Vostokova (an older Widow), along with Natalia Romanova, though she was unaware of the mission due to her age and came to view them as her real family. After Natalia defected from the Red Room and became an Avenger, Yelena defected as well and tracked her down in Morocco, later becoming a member of the Thunderbolts / New Avengers after her adoptive sister's death.
