Joe Mach

He's the operator of BlastMan.EXE and appears in MegaMan Battle Network 6.

He appears as Lan's teacher in the Central Town School. He's kind but strict. He gives Lan his student card after he gets stopped by security robots. During BlastMan's attack on the school, robots attack the students. He attempts to fight them off but is defeated. He gives Lan the teacher card so that he can go into the faculty room and the control board there.

Joe Mach appears again when Dr. Wily asks the operator of BlastMan.EXE to appear. He helps Blackbeard and DiveMan.EXE to kidnap MegaMan.EXE. They suceed and when Yuika, Ito, and Vic decide to turn against the WWW, he refuses and leaves. When Lan went after the ex-WWW members who kidnapped Iris.EXE, he arrives to save them and Baryl. He also reveals his reason for joining the WWW. His daughter was sick with a deadly disease and he couldn't pay for an operation to cure her. But Dr. Wily appeared and paid for the operation. Indebted to Wily, Mr. Mach joins WWW, and is working undercover in the school, spying on the WWW benefactor, Mayor Cain. He also explains his relationship to Baryl. In a martial arts competition, he was defeated by Baryl but asked to train under him. Baryl accepted and they've been friends since.

He appears again when Lan and Chaud are cornered by Heel Navis, saving them. He distracts the Navis and led them on a wild goose chase. In the ending, Joe Mach was given a lighter punishment compared to the other WWW members, and appears one last time when all the students are graduating. He tells his students good luck and congragulates them.
