Archie Andrews is a high school football player and aspiring musician.

The teen has had a number of romantic flings, including an affair with his music teacher Ms. Grundy, a brief relationship with Valerie from Josie and the Pussycats, and is currently dating Veronica. He turned down the position of football captain to focus more on his music and helps with his dad's construction business. The first season ended with Archie being a witness to his dad being shot.

Fred Andrews, Archie's dad, owns his own construction business.

Fred is a single parent since he and his wife separated, which helped form a close relationship between father and son. The divorce has not been finalized. He used to be best friends with Jughead's father, FP Jones, in high school, but the two now have a complicated relationship. His fate was left hanging in the balance after he was shot by a robber at Pop's diner.

Mary Andrews moved to Chicago after separating from Fred.

Mary has been gone for two years when the first season of "Riverdale" starts. Fred travels to Chicago to finalize the divorce. But after the parents receive a tearful phone call from Archie, they return to Riverdale together. She eventually returns to Chicago, but not before extending an invite for Archie to move back with her. He declines.
