I remember people speculating Necrozma created Ultra Space and the UBs with his energy emitting from his Ultra form, and that story Kukui mentioned about people fighting back darkness long ago was clarification that Necrozma WAS not a victim and was an enemy, and was buried in Ten Carrot but woke up when Lusamine fucked with Ultra Space. Never got anything from that, just have to use headcanon.
Oh yeah and Eternatus was a joke lmao. Tumordeer got more to him than that thing.
