Fan Casting Shadow the Hedgehog in Sonic the Hedgehog (2025 TV series; art directed and animated by Yuji Uekawa)

Known as the Ultimate Lifeform, Shadow is an artificial black hedgehog with red stripes, having been created by the late Professor Gerald Robotnik aboard the Space Colony ARK. Shadow is very serious, introverted, and blunt, often preferring to work alone. However, that doesn't make himself selfish, as he does care about others and is willing to help them.
