I have heard people saying chaos9 yet I could not find a team by that name
a cs team and people call them chaos9 because 3 of c9 players are from that team
chaos esports were a CS team that vanity, leaf, steel, xeppaa, and jonjii were all a part of and they pulled off a lot of upsets
since then leaf and xeppaa both transfered to Cloud9 valorant and vanity recently joined them hence: chaos0
