Rubén "Junior" Rivera is the son of Lulu and Ruben Rivera, the younger brother of Alma Rivera and a supporting character in Alma's Way. He can often seen holding his favorite dinosaur toy Steggie. Junior is reserved, a little introverted, and often gets shy meeting new people. But, he still has child-like energy and a wild imagination. He loves rapping, making dance moves, and playing with dinosaurs. He gets easily frustrated and can be a bit stubborn at times. He may refuse to communicate his needs or what's bothering him, but he always comes around once someone shows him that they're willing to listen.
