Fleetway super Sonic is the form that Sonic turns into in the End of Hope Ending of Sally.exe Continued Nightmare: Eye of Three. In-universe, it is his Dark Super form. He is taken from Super Sonic from Sonic the Comic. He is voiced by DarkBox.

Sonic transforms into this form in the End of Hope Ending as a result of rage after Chaos Hunter convinces him that Exetior is evil. He proceeds to try to fight Exetior. There are three outcomes to this battle: Sonic overexerts himself and dies, he gets killed by Exetior, or he defeats Exetior but is driven to suicide by Sally.

When in this form, Sonic is furious, violent, vengeful, and very determined to eliminate his target, to the point where he can potentially overexert himself and die. Unlike his comic counterpart, he has no fixation on destroying everything.

Super Sonic looks like the normal Super Sonic, but has red, swirly eyes. He has sharp claws and spiked hair. Super Sonic also has fangs.

Super Sonic has the same abilities as his regular self: flight, super strength, super speed, etc. Unlike his comic counterpart, he can’t shoot Laser Beams from his eyes.
