UnMario

UnMario was a friend of UnBarney, but now they are a group of evil capitalist fuckheads because they removed our dear leader Father Strange's rights and haven't remoted him unlike the past flags. Fuck UnMario! They abuse human rights, they sleep in body bags that have dead humans and more disgusting shit, but not as disgusting as UnAnything.
Hi, Dee here, from the UnAnything Wiki. It is in my best interest that I explain the truth.
The real truth.
UnMario was an ancient wiki-city (and later wiki-state) founded several years after the creation of FANDOM itself in 2007. It was the predecessor to today's UnAnything Wiki, of which is a successor wiki-city which followed the footsteps of UnMario & subscribes to several aspects of Marx's communism. This includes having all companies being owned by the city itself & providing a self-sufficient set of amenities to citizens.
The city of UnMario was, while an influential wiki-state later on in its lifespan, very shortlived. This was mainly due to infighting amongst bureaucrats over whether or not UnMario should participate in Mariogenics - that is, the improvement of the wiki's quantity & quality of its Mario pages. This would lead to the Battle at Shroob City, where brutal losses occurred on both sides, until the entire city was set on fire by a couple of toddlers outside of the city.
This would eventually lead to the collapse of UnMario, in which all of its citizens moved on to splinter wiki-states - including UnAnything. The fate of the city was unknown even to the survivors of the Great UnMario Fire; that is, until a couple of archaelogists found it quite recently...
We continue on to the present-day. The infamous Daddy-Long-Legs Stane, who also governs this propagandic wiki, found out about this new discovery after a few UnAnything teenagers threw a Molotov cocktail containing cold fire & a poorly drawn picture of the archaelogist's discovery; he considered this a "teroris atac" and sent his army of armchair mods in "cars" after them, but soon got distracted and decided to travel to UnMario. 
Of course, the archaeologists were busy at work attempting to clean up the rubble of UnMario once he did arrive, and figured they might need some help; so they gave him a Swiffer with a few pads and told him to clean up the rubble with them; of course, he would make a quick trip back to UnBarney and talked all about how "he discovered le epik city of UnGayrio" and how "he hads an 300 people teem to cleen"; he would never actually contribute to any of the work in cleaning up house and would spend most of his days at UnMario drinking a battery-juice margarita. This was until he was barred from the team since they figured he wouldn't actually contribute much at all, and also due to learning about a recent controversy regarding his risqué depiction of the actual UnMarian rubble itself.
Angered with this "demoton", he would later type up a rage-fueled post on his blog about how "evl capitalism has stroked me don". Now, you may be wondering, who were these "evil" archaeologists who kicked Stane off the team? 
It was us. It was the "evil UnAnything" people who peacefully told him to not make any risqué images and everything would be dandy fine. Now you know the truth, UnBarnians. Wake up. Wake up. Wake up. Wake up. Wake up. Wake up. Wake up. Wake up.
