Rush (ラッシュ) is Mega Man's faithful robotic dog, created by Dr. Light to assist Mega Man in his travels. He debuted in Mega Man 3. Initially, Rush was able to transform into a coil, a hoverboard, and a submarine. Since then, Rush appeared in most games related to the original Mega Man series. He appears only in SSF2 with one minor appearance (two if early demos are included).
