The Freedom One was a ship used by the Kingdom of Knothole in 3237.
When a mysterious earth quake occurred, Rotor decided it was best to investigate. The Knothole Freedom Fighters took the Freedom One to the origin of the quake, which turned out to be an ancient facility home to Isaac and Dr. Ivan Kintobor. After Sonic, Shadow, and Metal Sonic discovered a nuclear missile within the base, Isaac had the facility's defensive systems destroy the Freedom One to prevent everyone's escape.

- Freedom One had a unique design in its debut in StH #145, but was later depicted identical to the Freedom Fighter Special in StH #147 and StH #149.
