BeastMan.EXE

BeastMan.EXE, known as SavageMan.EXE in the English anime dub, is a NetNavi boss in MegaMan Battle Network 3. He is mistaken by MegaMan for a virus in their first encounter and he states that he hates humanoid NetNavis.

MegaMan Battle Network 3
BeastMan first appears as the boss of the second scenario, where he used the chips planted in the animals at the zoo from Yoka to take control over them. To get to him, the player must pair up animal programs (all are Mr. Prog) puzzles to deleted viruses blocking the way. He later appears again in Undernet 3 in the same place the player fought FlameMan before as one of the ranked Navis from the Undernet.

Once you beat him twice he will appear in the dog house next to Lan's house but you need the subchip Sneak Run.

MegaMan's Revival
With Takeo Inukai's return in the Battle Chip GP, confirming his survival from Wily's "deletion", he and BeastMan seemed to play part in MegaMan's revival. After MegaMan was absorbed by Alpha, there was a pitch-black scene with these dialogues:

"Where... am I? Am I... Alive?"

"Grrr... Grrrowwlll..."

"What do you... want? Will you... save me?"

"Grr... Grrroowll!"

When it could be Gospel who was growling, and the one's speaking is Bass.EXE, revealing his survival to become BassGS, it could be assumed that it was BeastMan.EXE who was growling and MegaMan.EXE who was talking. Even MegaMan's revival is thanks to Dr. Hikari's left program, it could be BeastMan and Takeo Inukai who took MegaMan out from inside of Alpha, as it pretty much explains the growling beast-like voice and Inukai's absence during the Final Battle in MegaMan Battle Network 3 when Lan have to use a Pulse Transmission device. If Inukai wasn't absent, there wouldn't be any empty Pulse Transmission device left, leaving Lan unable to act. Still, if this were true, Inukai and BeastMan's reasons are unknown for saving MegaMan. This couldn't be confirmed, as both Inukai and BeastMan didn't appear at all from MegaMan Battle Network 4 and the rest of the series.

MegaMan NT Warrior
He appears as a Darkloid in Axess and works for ShadeMan. BeastMan is the first Darkloid fought and attacks SciLab through a Dimensional Area and attempted to destroy SciLab to prevent anybody from stopping Nebula. However, Lan and MegaMan Cross Fuse and manage to drive him off.

He is encountered once again in Axess when he attacks a Mall with a Dimensional Area. This time, his power has been increased by the power of the Dark Chips and Lan needs Metal Soul to defeat and delete him. He is later revived by Dr Regal but is deleted by Megaman in Proto Soul.

He returns in Stream as an Asteroid Navi. His operator is Takeo Inukai. Like the other Asteroid Navis, he is able enter the real world with the aid of the Dimensional Chip. He is deleted after disabling Sci Lab's dimensional generators.
