Vivienne Medrano also known by her online alias VivziePop, is an American animator, writer, director, illustrator, comic creator and voice actress. Though she is best known for her later projects "Helluva Boss" and "Hazbin Hotel," Vivienne's first major success was a webcomic titled ZooPhobia. It was in 2019 when her YouTube channel took off after posting the pilot for "Hazbin Hotel." Not only did this pilot spawn an entire spin-off set in the same universe ("Helluva Boss"), but the show itself was picked up by A24 and later Amazon to be made into a full-fledged production. Currently, Vivienne continues to produce both shows while running her own production company Spindlehorse Toons.
