Not surprisingly, she is the wife of the Junk Store Man, although she is actually the one who runs the shop.

When MegaMan enters the Junk Shop looking for parts with which to repair the Flutter, he finds the Junk Store Man is out. The Junk Store Man's Wife asks him to fetch her husband from the ruins.

It turns out that the Junk Store Man's Wife was once a digger and her husband acted as spotter for her. The old truck which sits outside the entrance to the Apple Market used to be their spotter car.
