If this leak is real we could be looking at the updated design for Sonic in his new movie. It is definitely a massive improvement over the original design that more resembled a person in a knock off Sonic suit than the actual blue blur. However you should probably take this with a grain of salt, there are plenty of bored graphic designers out there. The design for Sonic was changed after mass Internet outrage after the first trailer released in April.
Sonic The Hedgehog will speed into theatres on February 14, 2020.
