The July 2019 patch introduced 17 new starter Sims in Create-a-Sim. Below are images of the new Sims that will randomly generate when you start a new game via the main menu, and they include the new Sims from the new Sims 4 brand render.
❗ Sims added via the December 2018 patch will still generate as well.
❗ I randomly generated their traits and names. You will have to wait for Maxis to upload the official household of the new render for their official names and traits.
