For those wondering where/if she's even in DBS: Broly--- Seripa can be seen here (with the rest of Bardock's squad, so that's cool! :D) when Frieza first arrived on Planet Vegeta as shown in the movie's opening.

Additionally, for those wondering where she went after that, Toyotarou drew art (under 14) showing where he thinks she and the rest of Bardock's Z-era crew were.
