Schematus
Schematus is an incredibly intelligent yet obsessive Supergod(?) who spends most of his metatime conducting experiments in futile attempts to regain his lost memories. Schematus is utterly obsessed with finding out just what happened to his Beyond Bubble and friends, particularly his own past. Schematus will exert absurd amounts of energy looking for any possible clues as to what happened, along with conducting just about every conceivable experiment possible in hopes they might help him in some way.
None of his research ever actually works, leading Abnull to question why he even tries at all. Especially the fact that many of the results of his experiments and research are utterly incredible and revolutionary in their own right, yet Schematus discards them as 'failures' purely because they don't help him regain his memories. Among his discarded 'failures' have been manipulatable Metaslime, the indestructible compound Delgam and a cure for Omniscience^3. Despite Abnull's great respect for Schematus, she is utterly infuriated at his absurd obsession and complete lack of perspective. Negatil's view of him is significantly less charitable.
Nobody is completely sure what Schematus actually is. While he certainly resembles a Supergod and is composed of Godsmoke, his biology is nothing like any Supergod known and defies more conventions than considered possible. Despite this, he still resembles a Supergod more closely than any other Transcendent Ecosystem creature, and is thus considered a Supergod.
Schematus is classed as Omnipotent^2 and Omniscient^3 on the Omnipotence Hierarchy, however his form of Omniscience^3 acts nothing like the standard Omniscience^3 held by Supergods such as Xenixel, Unthil and Matharin. Instead, his Omniscience^3 appears to act as a wealth of pre-existing knowledge which he does not have to 'tap into' at all but is much more limited in scope than the standard condition. (Although the actual quantity of information is roughly the same.) It is suspected that he has a completely different condition which just so happens to place his Omniscience at a similar level on the Omnipotence Hierarchy.
Schematus's strange obsession with uncovering his past means he very rarely if at all interacts with or speaks to his fellow Supergods. The only one he has any kind of actual relationship with is Abnull. Abnull greatly respects Schematus and considers him the most competent Supergod in the Bubble, though she wishes he would put his amazing intelligence to better use. Schematus neither appreciates nor dislikes Abnull's support, though he's significantly more annoyed by Positev's blind support, which he suspects to be completely disingenuous and merely an attempt to disagree with Negatil.
Schematus's only interactions with Monopolum and Binauris are studying their strange conditions as part of his experiments and often forgets Peralitus exists entirely. Abnull is amazed by his ability to ignore Peralitus, which she considers to be more impressive than any of his experiments and deeply wishes she could learn such a skill.
Strangely, Schematus has significantly fewer memories of his life before the Calamity compared to the others, and is especially lacking in memories related to the deceased Supergod Barelitil. Nobody is quite sure why, though Schematus has done an uncountably infinite amount of research into this detail regardless.
Abnull
Abnull is a horribly deformed and nihilistic but caring and pragmatic Supergod who is the closest thing her Beyond Bubble has to a leader. Abnull was literally torn apart during the calamity, leaving her Godsmoke broken and jagged. Strangely, most Supergods in this state (such as Empiroxus) would quickly fade from existence, however Abnull has remained completely stable for as long as she can remember. Nobody, including herself, is quite sure why.
