Considering the World of Valorant is taking place in 2039, I wondered what Agents are in which Generation group, so this is what I got so far

Millennials(1981 – 1996): Brimstone.

Gen Z(1997 to 2012): Viper,

Cypher,

Sova,

Sage,

Reyna,

Yoru,

Breach,

Astra,

Chamber,

Fade.

Gen Alpha(2013 to 2025): Killjoy,

Phoenix,

Jett,

Raze,

Neon(Youngest).

Since Valorant mirrors our world, Neon is 2 years old and Brimstone is 33 years old, this year.

Okay Kayo don't count because he is a Robot. Omen is strange I think he is Gen Z, because of the voicelines from Viper and Sage, it makes sense as well as his past Friendship with Viper.
