The Art of Destruction

The Art of Destruction is the 48th episode of Sonic Underground. The plot is that The Sonic Underground come across ART, Robotnik's most powerful robot ever, that can think and learn for itself. But ART soon learns the power of friendship, and switches to the Resistance. This gives a vengeful Sleet the opportunity to finish off ART - and the hedgehogs - once and for all...  The song for this episode is called The Sound Of Freedom.
