Rivera attended Vicious State, where he majored in Criminal Justice. Three years later, however, Rivera discovered his scaring talent, which eventually landed him a job at Fear Co. He moved to Scream Industries prior to taking his current place at Monsters, Inc.
Rivera was working at Monsters, Inc. at the time of Boo's escape into the Monster World. Hours before her entry, Rivera was working on Scare Floor F, collecting screams with the help of his assistant, Benny. On the Scare Board, Rivera peaked at the fifth position, staying far behind front-runners James P. Sullivan and Randall Boggs. After Boo was returned to her home in the Human World, Sullivan and Mike Wazowski turned the scare floor into a laugh floor, and Rivera began collecting energy through making children laugh instead of scream.
At some point in his career, Rivera received a scare card that detailed his physical and biographical information, as well as his scare records.
Personality and traits
Rivera stands at 6'11", and weighs 208 pounds. He is a tall, slender monster with two eyes on small stalks, six long tentacles serving as arms, and four shorter tentacles serving as legs. Rivera's skin is orange, with green stripes around his legs, and pink tips on his arms. His snake-like tongue is turquoise.
Josh is similar in appearance to Tony, though he lacks a fifth leg and mustache. Additionally, there are several background monsters that share the same model as Rivera, such as the Waiter at Harryhausen's.

Rivera is likely named after Jonas Rivera, who worked in the art department on Monsters, Inc.
