BLUE gender, an odd show at late night, shows a bunch of bugs suddenly show up on earth out of nowhere after they did some experiments with DNA(sounds very familiar to evangelion if not the same story/premise). they were a “alien” bug race that has a quasi-hive mind and has the ability to evolve against human weapons/tech, whatever they through at the bugs the newer bugs had some kind of adaptation, thier only weakness is a “core”, every new evolution line have them hiding the core, until the very end where the a super bug had no core at all and was extremely poweful against thier mechs. apparently japan has a wierd obsession with GUINA/guinan highlands in SOuth america(Irl IT HAS origins of specific unusual plant lineages, and may some other species) as they traced the bugs origin to that area where a mysterious “structure”. pratically the bugs was the earths way of wiping out humanity because they were destroying the earth.
