While now common in various shooters, particularly Overwatch 2, "C9" traces its roots back to the original Overwatch in 2017. During Apex Season 2, Cloud9, a dominant team, faced Afreeca Freecs Blue. Despite their superior skill, Cloud9 inexplicably prioritized individual kills over the objective on the Lijiang Tower map—holding the point.

Stunned commentators and spectators watched as AF Blue capitalized on this lapse, securing an unlikely victory. Incredibly, Cloud9 repeated this mistake twice more! This legendary blunder, dubbed "C9" (short for Cloud9), lives on in streams and professional matches.

Others insist that a true "C9" stems from human error—forgetting the primary objective. Given the original incident, this interpretation seems most accurate. Cloud9, despite their skill, abandoned the point without clear necessity.
