ART, "The Art of Destruction"

ART (short for Artificial Robot Technology) is a character that appears in Sonic Underground. It was a robot and one of Doctor Robotnik's most powerful creations, developed for the purpose of defeating the Freedom Fighters. However, it defected to the Freedom Fighters and sacrificed itself for their cause.


ART was sent to capture the Hedgehogs, going through two form changes as he attempted to abduct them. Despite managing to thwart him several times, the trio were caught by ART while rehearsing for a concert. However, ART had heard them play, and requested a song. The group obliged, and ART's free will was activated by the music, even leading him to play a keyboard similar to Sonia's.

ART defected to the Freedom Fighters, using his impressive abilities to free prisoners and destroy Swatbots. However, he and the Hedgehogs were later caught in a crushing chamber. Using his strength, ART blasted a door so that his friends could escape, but he himself was crushed.


While ART's time with the Resistance was brief, he served to inspire Manic the Hedgehog, who at that time had been feeling as though the efforts against Robotnik were pointless.

Powers and abilities

Able to absorb any technology into his frame to increase in size and power, ART is a learning robot, capable of adapting to anything his opponents might deploy.
