Asteroid Gravityman What a delight it was to see Gravityman reappear again, even if it was for only one episode. This overlarge navi is used by two criminals by the names of Mac and Harry, in order to make Manabe think she is gaining weight. It would seem these two guys have a grudge against our fellow Net Police woman for messing up one of their schemes. Like many of the other Asteroid navis, Gravityman ends up forsaking his new operators, and becomes bent on destroying everything in sight. This rabid behavior forces Netto and Rockman, along with the help of Colonel, take him down for good.

This guy is actually smart enough to run away when he's beaten. Till Colonel hunts him down anyways.
