Subcultures among subcultures have existed for as long as humans in their infinite creativity existed.

• Babyfurs and Diaper Lover Furries-They focus on regression. And they really love diapers.

• Densha Otaku - They love photographing trains. They also get extremely violent when you ruin their shot of trains.

• Cyberdeck Builders- They build retro computers with 80s SciFi aesthetic and take things too far.. Using or even building hardware to mimic timigs exactly like they behaved in 70s.

• Grandmacore - People obsessed with grandma aesthetics. Very. Very. Obsessed.

• Swedish Raggare - American 1950s greaser culture filtered through rural Sweden and dialled to 11.

• Sapeurs - Rural Kinshasa men spend 1000s of dollars, sometimes sacrificing rent and food, to buy high end designer shit from Europe. They walk through dirt roads dressed like 19th century French dandies.

• Otherkin & Therians - They think they aren't humans or at least partially non humans.

• Birds aren't real- They think birds aren't real. And that they are all robots, drones sent by CIA or other secretive gangs.

• Chronological Revisionists - Popularised by a German historian named Heribert Illig, followers of the Phantom Time Hypothesis believe that the Early Middle Ages (specifically 614–911 AD) never actually happened. They claim that Holy Roman Emperor Otto III and Pope Sylvester II completely fabricated three centuries of history, including the entire existence of Emperor Charlemagne, just so Otto could rule during the monumental year 1000 AD. According to them, we are actually living in the early 1700s.

• The Tartaria - They believe that a technologically advanced, global utopian empire called Tartaria existed until the late 1800s. This empire supposedly used the domes and spires on old buildings (like world's fair pavilions or old European castles) to pull free, wireless electromagnetic energy straight from the ether. They believe a massive, worldwide "Mud Flood" wiped them out, and modern history was rewritten to hide the existence of free energy.

• Deros Believers - Shaver claimed that humanity used to share Earth with an ancient, advanced race. When the sun started emitting toxic radiation, the advanced race fled the planet, leaving behind their underground cities. According to Shaver, these caves are now inhabited by Deros (Detrimental Robots)—degenerate, sadistic humanoids who use the abandoned ancient "ray technology" to project voices into the minds of surface-dwellers, cause freak accidents, and steal our thoughts.

There are a few more.. But I'm too bored to type them here.
