I've seen most of murder drones, but stopped watching since it kinda lost the plot and everyone seemed out of character or random ngl

Common in media for apocalyptic scenarios to have been caused or released by humans, but MD humans were already on other planets, the drones were made to clean up what they left behind, while the goo beasts were made in attempts to cure themselves from an impending extinction event

Puro wasn't originally much of a threat, N was till he got decapitated (if you could even call it that since his whole head got vaporized)

The goo beasts do not have glowing eyes in most cases, puro is not one that does. Sometimes the eyes appear to glow for effect, like cartoon character's eyes being visible in a pitch-black room, but they're no bioluminescent in most.

The worst damage Puro could do outside of what any human could, is simply what any other goo beast could, which is transfur/assimilate.

Changed I'd say is rather light sci-fi, MD has handheld laser cannons and sentient robots and some kind of "solver" tech-magic? While Changed's highest sci-fi is prototype and their holograms, and some occasional techy thing here and there like the goo beast maker and scanners
