Joon the king just dropped a piece on this guy.
I was a really young lad playing pokemon showdown back in the day when i heard about this dude (~2015), i was really addicted at climbing the ladder at that time and i jumped in the bandwagon of hating that dude along with other smogonites.
VGC is the shitty format used by Nitendo to host flesh space tourneys.
I will spare you the details of why this format is shitty, but it basically boils down to the fact Nitendo forces you to use two pokemon at the same time and it also allows for all the broken rng and mechanics that exist in the game, those two things make battles last only a couple minutes of almost complete guessing work that requires little skill.
Nitendo forcing two active pokemons specifically done so tourneys ended faster and then have people buy merch or whatever they do in those conventions, nobody liked it because double battles were rarely shown in the anime or the video game series, and it was really unfun to play.
Pokemon Showdown (PS) is a pokemon battle simulator, it is funded, supported and directly linked to Smogon a xenoforo forum site just like kiwifarms, this site is a collaborative attempt at producing resources aimed at supporting fun and balanced competitive play, it mainly produces its own ruleset and tierlists that are then used in PS.
Anyway, that dude would use PS to test his VGC gimmick set ups and people would just own him all the time, even 1100 elo noobs destroyed this guy and would make fun of him on his comments and he eventually got triggered about it and started posting those seething videos.
I remember we would just snipe his username and make his fun of him in battles, it was hilarious, it just went to show how behind and archaic the vgc scene was compared to internet battlers that honed their skills in the comfort of their chairs and dorito dust crusted fingers.
Another reason that I think he was so triggered is because those MLG type indie tourneys at that time started using Smogon/PS rules instead of mainstream nitendo rules, so he was worried he would his popularity if nitendo decided to ragpull their operations.
I guess he turned out as some sort of furry since then, it is sad, i guess those meme response videos smogon dudes made about him being molested by his dad got to him, regardless Ill ignore reading the furrfaggotry and only remember him for this cringe autistic drama from when the internet seemed so pure.
