JunkMan.EXE

JunkMan.EXE, known as JunkDataMan in the English anime, is a NetNavi born from junk data. He is a Solo Navi.

MegaMan Battle Network 4
He first appears as Lan's opponent in the Blue Moon tournament. While MegaMan.EXE is in Yumland, a large pile of junk drops on him in the Net. Lan tries to jack him out and although it doesn't look like it, he seemed to have escape. However, MegaMan acts strangely, saying that he wants to withdraw from the tournament; it is soon revealed that he is JunkMan in disguise. Lan makes JunkMan dig out MegaMan, who is buried in the trash. After leaving, Lan and MegaMan wonder why he's so alone, and they get a Kindness data to try and cheer him up.

In the tournament, they offer the data to JunkMan as a gesture of friendship, but he destroys it. The two then Netbattle. After being defeated, JunkMan explains the reason for his solitude. He was born out of JunkData and never had a NetOp. He entered the tournament because he knew he was falling apart and couldn't last any longer. Even as they talk, his data deteriorates. He states that he enjoyed being in Lan's PET and he was grateful that they had shown such kindness to him; he then erodes away. Lan and MegaMan are touched by JunkMan's story, and MegaMan gains his Double Soul.

Megaman NT Warrior
He gathers up space junk, sattelites, and everything in space execept for planets to make his castle. This causes trouble for Yai, who inquires for Lan and Mayl to help her. Upon having Glide, Megaman, and Roll meet him, they battle but they decide that Junkman didn't need to be deleted. They simply taught him which peices of junk he should collect and which ones he shouldn't. Then the gang leave space with JunkMan as their friend.

JunkMan appears once more when Scilab attempts to destroy Dr. Regal's space station with their attack sattellites but all are destroyed. He also damages JunkMan's space station. JunkMan then helps Lan and MegaMan find and board Regal's station and gives Megaman Junk Soul.
