Dillon Gu, known by his online alias DillonGoo, is an American animator, director, and content creator. He is best known as the lead fight animator for the Rooster Teeth series RWBY starting from season 3 and for his Anime Cats YouTube series, as well as the cyberpunk-themed Genshin Impact fan series Progenitor, as a VTuber under the name Professor Goo, and as the founder of DillonGoo Studios. Through his studio, he has developed engines for Blender and collaborated with the Blender Foundation, as well as Blizzard Entertainment, HoYoVerse, Yostar, Gryphline, and Kuro Games, in addition to creating the 3D animated web series Soul Mart in 2025. He is a partner of the Blender Foundation since 2024 and is also an affiliate of the Kadokawa-backed agency GeeXPlus since 2025.
Career 2012–2024: Early career Before pursuing a career in animation, he majored in computer science. He subsequently joined Rooster Teeth to work on RWBY before eventually returning to independent animation. Starting in 2017, DillonGoo created KatsuWatch, an animated web series which features Overwatch characters depicted as cats, with Blizzard Entertainment commissioning him for an animation related to Ana's Bastet Challenge, where Ana Amari is shown fighting crime while dressed as a cat. Additionally, Gu created an animation of Baptiste as a cat, nicknamed "Catiste", as well as an animation for Widowmaker. In 2022, DillonGoo Studios released the Goo Engine, a custom build of Blender designed specifically for use in 3D anime production which also serves as the studio's in-house version of Blender. In November 2023, DillonGoo Studios launched Emily, an anime-style 3D rig for Blender. Following this, Gu created a hand macro control rig in Blender in May 2024.
2024–present: Continued success and Soul Mart In March 2024, following Rooster Teeth's announcement of its impending shutdown, Gu expressed interest in acquiring the intellectual property of RWBY to continue its run. He went viral in November 2024 after retweeting a video of a cosplayer dressed as Link from The Legend of Zelda, who was struggling to unsheathe a sword from their back. He tweeted a video demonstrating how the sword could be drawn from the side instead of the back opening.
DillonGoo has also collaborated with HoYoVerse and therefore made a number of Genshin Impact-themed animations for the HoYoFair program starting with the animated short "Nameless Road" in 2022, followed by the cyberpunk-themed Progenitor web series, among the works featured include the Fontaine-themed The Last Bakery in 2023, as well as the fourth episode of the web series If Genshin had a Cyberpunk Anime: Progenitor in 2024, which was featured in the HoYoFair program that year to coincide with the fourth anniversary of the game.
In December 2024, Gu and DillonGoo Studios announced their partnership with the Blender Foundation to assist with new Blender releases and the development of non-photorealistic rendering features.
In May 2025, Gu announced that he had joined the Kadokawa-owned Japanese talent agency GeeXPlus. Two months later, in July 2025, during a GeeXPlus panel at the Anime Expo following the announcement of GeeXProduction, DillonGoo, along with GeeXPlus members Gigguk and OtakuVs, announced their projects, in which DillonGoo announced his 3D animated web series Soul Mart. In an interview with Anime News Network, Gu stated that he wanted to demonstrate to a Western audience that animation is not solely for children or adults, but can occupy a middle ground. He also mentioned his interest in experimenting with the integration of 2D elements within 3D animation within the series.
