so uhhh small but important lore update for Hypernova ye ye
the Three Cosmic Entities (3CE) — the main trio of those robot guys — are now called the Three Cosmic Automatons (3CA)
basically, they were only cosmic "entities" — in a very loose sense — in the original Hypernova, due to having those vortex thingies inside them; after Omnision gets his

kicked at the end, the vortexes cease to exist but the three continue to work only off of their programming (which has been a direct 1:1 of the vortexes' controls for a while anyways), making them full-on robots so the old name simply didn't fit
i couldn't find anything other than "automaton" that signaled their robotic nature while also keeping the abbreviation sounding nice ("3CA" sounds more like "3CE" than something like "3CR")
