Dark MegaMan.EXE

Mega Man Battle Network 4
During an encounter with ShadeMan.EXE, MegaMan is forced to use a dark chip in order to defeat him, creating a dark soul within him. Throughout the game, MegaMan struggles with the temptation of using dark chips, which would make his dark soul stronger and corrupt him further. Duo.EXE eventually forces MegaMan to battle the darkness within himself, which manifests as Mega Man DS.

Mega Man Battle Network 5
MegaMan himself is finally fully transformed into Dark MegaMan when Nebula captures him and fills his body with dark power, placing him in charge of the first half of End Area. After he is defeated during the liberation mission, he returns to normal. The battle with Dark Mega can be easy or hard depending of what kind of chips and weapons the player uses, as it can use all the battle chips and P.A. used in the game until that moment. Unlike the previous game, where his HP total was the same as the players, it's preset by version.

Dark MegaMan is also found in Nebula Area 6 as the "Chaos Lord" if the player takes two minutes or less to defeat all the DS Navis after their initial defeat. However, there is no bonus for redefeating Dark MegaMan.

The Dark Soul was deleted from MegaMan after the events of Battle Network 5 when he becomes Hub and defeats Nebula Grey, destroying the Dark Soul within himself.

MegaMan NT Warrior
In the manga series, Dark MegaMan and LaserMan mysteriously appeared after a defeated Bass collapses after a confrontation with MegaMan. Dark MegaMan had been causing other Net forces to confuse him with the real MegaMan, and he even planned to absorb the last of Bass' power. But to do this, he needed enough energy that stemmed from MegaMan's hatred for him. So, to become strong enough to absorb Bass, he needed to trick the actual MegaMan into detesting him deeply, often by putting loved ones in danger, like his NetOp, Lan. He eventually does absorb Bass, and LaserMan as well, betraying him, but he is eventually defeated.

Abilities
Dark MegaMan possesses all of MegaMan's abilities, but enhanced with the power of darkness. That is to say he has access to all of MegaMan's programs, Battle Chips and Program Advances, and is able to use Dark Chips indefinitely without penalty as it is a being made of Darkness. In the anime, Dark MegaMan has ingrained the battle patterns of both MegaMan and Lan, essentially making him the two of them combined in one and is able to outmaneuver them by thinking like them. However, due to lacking bonds like the central duo, he cannot mold his strategy instantly like they do, due to their developed teamwork.

In the manga he is shown to be able to quickly recover from any damage, change the shape of his hands, and the ability to use Dark Aura. When he temporarily absorbed Bass, he had all of his powers. He later absorbed LaserMan and gained his laser powers.
