JammingMan.EXE

JammingMan.EXE (ジャミングマン) is a NetNavi from the Mega Man Battle Network series.

Rockman.EXE Phantom of Network
JammingMan is a NetNavi created by Cache. In Chapter 6 he uses his jamming abilities to cause chaos in the Cyberworld, making several devices to break and cutting communications. When MegaMan finds him in Mobile Area 4, he cuts his contact with Lan, almost forcing him to battle only with his Buster. Despite the interference, Lan manages to contact MegaMan and send Battle Chips, and they manage to defeat JammingMan.

JammingMan reappears in Chapter 7 to cause interference and protect Cache, forcing MegaMan to retreat. After receiving protection against his jamming, MegaMan faces him again alongside a cache copy of FireMan in the final chapter. After Cache's defeat, he summons 10 JammingMen to cause a powerful interference that forces MegaMan to lose contact with Lan. However, their strong bonds allow them to keep contact despite the jamming, and they defeat Cache.

Rockman.EXE Beast+
JammingMan works for Cache.

Abilities
JammingMan has the ability to create powerful interferences, jamming the network.

In Beast+ he is shown to be able to prevent Navis from logging out. His abilities can also influence the human mind, as seen when Lan sees his friends and family try to attack him. In reality, however, a great number of JammingMen were attacking him.
