Blastman has fire powers, that are very common yet they still pack a punch. Greenman probably doesn’t have fire and is probably not good against it. Blastman could beat him in one hit. Blastman wins.
Blastman has had his downs to be sure but maybe things are finally looking up for him. He wins this match handily because of his mastery over fire. Silk doesn’t have a mastery over anything yet. Blastman wins.
Gravityman is pretty tough. After Savageman and Megaman he may very well be the best normal navi. Blastman doesn’t match up against him. Blastman definitely isn’t one of the best normal navi’s. Gravityman wins.
Savageman is pretty strong. He’s one of the strongest Megaman exe characters. He’s fought Megaman and Protoman teaming up. He is too strong for Blastman. Blastman is a run of the mill fire navi who can’t fight too good. Savageman wins.
Blastman is another fire navi to appear in Battle Network. Since he was in 6 he is the final one (to my knowledge) Blastman has no distinguishing powers amongst fire beings. Megaman would beat him with a water program advance. Megaman wins.
