Off the top of my head.

Chaotena the eldest child and daughter of Prime, Goddess of the Chaoverse and reincarnated in the Hexaverse as Greenback hence the name Greenback Chaotena. I think she was killed by Nightmare's father when she discovered what he was doing, either way she died and her universe was left godless for a long ass time until her rebirth.

Gaia the eldest daughter of Chaotena who sort of took over leadership of the Chaoverse hives and her other xeno siblings after her mothers death, she would eventually abandon this duty as the Chaoverse acted true to it's nature and fell the infighting and disorder and her siblings engaged in sororicide. She ended up becoming a devoted ally of Nox at some point which was a huge part of her character, she was technically a nature goddess and her own xenomorph line had evolved to bypass having Face Huggers and Chest Bursters taking traits via feeding instead while young and generally having a almost plant or fungi like side to their aesthetic of sorts.

Eveline or Eve the daughter of Gaia and granddaughter of Chaotena, similar to her mother in power and role but much younger and unstable as the curse of the Chaoverse from it's original master Omegan corrupted her over time leading to her becoming a problem to her mother and Nox's plans as she fell under the thralldom of the Old God, Dark-G. Had a a bit in common with her aunt (via reincarnation) Eris Treped aka Red Stripe and her great uncle Nightmare in terms of corrupted and being a problem for her relations.

Xenaria or Xena the youngest daughter of Chaotena via her reincarnation Greenback Chaotena. Young, unproven and heir to great responsibility, tended to take the form of the Human woman who hosted her as a Chest Burster. Often got into trouble but was ultimately loyal to her mother.

Oden/Odin the Yautja, loyal right hand and herald of Chaotena and Greenback Chaotena upon discovering in long awaited reincarnation. Turned his back on a lot of Yautja culture but was a stickler for his own interpretation of the Hunters code and honour. In later additions he was also a son of Shokande Azteca but I don't recall a lot of that lore me, D4 an Kuma came up with in that reguard.

Dark-G aka Dark Giganotosaurus, an Elder God from before the Big Bang. Powerful, ambitious, eternal. Took advantage of Chaotena's absence and Gaia's abandonment to usurp the Chaoverse and feed of it's energies while playing a long game as he recovered his long lost strength, encouraged it's chaotic and infighting filled natured before taking a more direct role in the formation of the Universal Union which he was the high god of. Used the Union to invade other universes of the Multiverse as part of the final rpgs storyline and would have played a big and climatic role in struggle although naturally it never got as fair as my and Kuma's brainstorming. Used the Balance Bringer a powerful Cetran artifact of their long extinct first one civilization as her mobile temple and throne as well as a battleship with the Absolute Zero Canon capable of destroying entire start systems by freezing suns into nothingness... also Jupiter sized because I was stupid lol.

There are others that I'm trying to recall but those were the big ones

Awesome Kumes that would be great and Gigs I have the Balance Bringer in my storyline, albeit lessened down in the size department. lol Its still Mercury sized though. Also, the Middle Realms and the story is coming along....still have a ways to go for the timeline to be done but I do have other planets and their main realms they are apart of.
