Trevor is a character that appears in the Sonic Underground television series. He is an anthropomorphic mouse who is a Freedom Fighter and friend of the Sonic Underground and Cyrus. He is well-connected and often provides Sonic the details of plans and missions.


Trevor's appearance is that of the stereotypical hippie, wearing sunglasses and a red shirt with yellow sleeves.


Trevor, a friend of Sonic the Hedgehog in the Resistance, was captured by Swatbots during a raid on Robotropolis. The Sonic Underground triplets were being trained by a monk named Thelonious, but they decided to return to rescue Trevor before their training was complete.[1]

Doctor Robotnik used drugs to alter Trevor's brain chemistry to put him into "beta open brain status", which would allow Robotnik to easily extract all information about the Resistance (and everything else in Trevor's mind) through interrogation. Trevor was being held in level 4, section C of Robotnik's stronghold. The Sonic Underground broke him out of his cell, triggering the alarm in the process, and hid in the ventilation shafts to escape detection by Swatbots.[1]

During the escape, Sonic Underground learned that Sleet and Dingo had found the cave of the Oracle of Delphius, and realized that they had to warn the Oracle before Robotnik launched an attack. Since every entrance was blocked, they decided to steal a plane from Robotnik's hangar to escape. Trevor single-handedly stole one of the smaller ships to lead the guards away, so that the Sonic Underground could exit the hangar in a second stolen ship pretending to be in the main force of pursuers. Trevor escaped by abandoning the ship, leaving it to be discovered by Swatbots while he got away.[1]
