Cathy Singer Smith

Cathy Singer Smith is a hedgehog who lives in the Facebook Galaxy. On his journey, Run the Hedgehog traveled with Cathy until learning she is the niece of Dr Robotnik. The two fought valiantly, but Cathy was somehow able to dodge all of Run's attacks. After their bout, Run kissed her and Cathy ran away from him. Cathy's design appears to be a blue and gray recolor of Amy Rose fanart.
