It looks like original concept art for Netflix’s upcoming Sonic Prime has leaked ahead of its 2022 premiere. According to dedicated Sonic the Hedgehog news source, Tails’ Channel, the concept art was first published by artist Patrick Horan as a part of his online portfolio. The images have since been removed from the original source but not before they were saved and shared:
Announced in early 2021, Sonic Prime is a 24-episode family-friendly adventure that is currently in development at WildBrain’s Vancouver studio. Alongside Horan, Betty Kwong (Ninjago and The Lego Star Wars Holiday Special) and Nicholas Kole (Crash Bandicoot 4: It’s About Time and Spyro Reignited Trilogy) are also working as designers on the upcoming show, which is scheduled to premiere exclusively on Netflix sometime next year.
