Rebecca Sugar is the creator of Steven Universe. She is an artist, composer, and director who is known mostly for her work with Adventure Time, another Cartoon Network original series, as well as her award-winning animated short "Singles" and her graphic novel Pug Davis, as well as assisting with characters and backgrounds for Ian Jones-Quartey and Jim Gisriel's web series nockFORCE prior to her career.
In 2012, Cartoon Network greenlit Steven Universe, making her the first solo female cartoon creator in the network's twenty-one-year history. Rebecca was one of the main storyboard artists on Adventure Time, before leaving production during the fifth season to work on Steven Universe, although she worked on Adventure Time again in 2015 for the Stakes miniseries, writing at least one song ("Everything Stays") and voicing Marceline's mother.
She also did a few storyboards on the Sony Pictures Animation film Hotel Transylvania.
Rebecca was born in Silver Spring, Maryland and attended the Visual Arts Center at Einstein High School and Montgomery Blair High School simultaneously in Maryland. Later, she would attend the School of Visual Arts in New York. One of her early works, a comic strip called "Don't Cry For Me, I'm Already Dead" about brothers who bond over references to The Simpsons was an early viral success. The strip was originally published on Sugar's now-defunct website, SugarBoukas.com, itself a reference to one of her early animated shorts.
She was eventually hired as a storyboard revisionist during season one of Adventure Time, and later promoted to storyboard artist in the second season.
Rebecca would eventually leave Adventure Time in early 2013 to launch her new cartoon, Steven Universe. Her final episode she worked on for Adventure Time, titled "Simon and Marcy", was difficult because she was working on that episode alongside with launching her new show.
She has achieved numerous awards in her career in television, such as earning nominations for Primetime Emmy Awards and Annie Awards while working for Adventure Time, and being featured in Forbes magazine's "30 Under 30 in Entertainment" list in 2012, noting that she was responsible for some of the best episodes of Adventure Time.
