But a post-credits scene shows one character who might be able to stand up to the indomitable heroes: Shadow the Hedgehog.
In Sonic 2, Sonic uses the power of the Master Emerald to smash a giant evil mech to pieces, and we see Dr. Robotnik fall and disappear into the rubble at the end.
He’s since become a staple of the series, and he’s a playable character in Sonic spin-offs like Sonic Riders.
