the most toxic and foul game I know would be anime battle arena.
it's a Roblox game, but the game is probably sweatier than any skill-based battle royale game.
here are some stereotypes just off memory for this game
Track stars: run the entire match, only play broken mobility characters such as Todoroki, Chika, or Rikka.
The apes: Will do anything to win a ranked match, when they're losing, they'll resort the running away or calling you racist slurs. They mainly play broken characters like Gojo or any dragon ball character
and lastly The hackers: Isn't even good at the game, 99% of the time still loses, plays characters with high damage output.
the game is fun don't get me wrong but like its still toxic asf
