You may be looking for Harry from the Mobius Prime universe.

Harry (Light Mobius) is the Light Mobius counterpart of Harry the Dingo cab driver from Mobius Prime. For the past few decades, Harry has been a cab driver and in recent years drove Emissary Rotor to Angel Island in order to arrange a meeting between King Sonic and Guardian Knuckles, saying he could back him up again anywhere due to his clearances. He later delivered a message from Rotor to Knuckles at his daughter's Unveiling. (StH: #131, #132)

It is unknown if Harry exists after the timeline was altered by King Sonic, or was one of the many erased.
