Dark MegaMan.EXE

Dark MegaMan, known as Dark Rockman (ダークロックマン) in Japan, is a dark version of MegaMan.EXE created from the darkness of Dark Chips.

Mega Man Battle Network 5
MegaMan transforms into MegaMan DS again when Nebula captures him and fills his body with dark power and places 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 and in return, destroying the Dark Soul within himself.

Rockman.EXE Battle Chip Stadium
Dark MegaMan appears in the game in Version 2 as a special playable character and using Battle Chips, you could use your Navi Data Chip to level it up. Also, your Navi Data Chip could be used in MegaMan Battle Network 6.

Anime


Dark Rockman.EXE is a major antagonist during the second half of Rockman.EXE Stream, having been created when ShadeMan.EXE bites Rockman, putting a Dark Aura in him. Later, when Rockman is saved by the Vaccine Chip, Dr. Regal appears as a ball of light and takes Rockman's Dark Aura, using it to create Dark Rockman.

As a boss
In Mega Man Battle Network 5, when MegaMan uses the Dark Chip DarkInvis, MegaMan will also enter a state just like MegaMan DS. Also in Mega Man Battle Network 5, if MegaMan uses a Chaos Soul and fails to use the charge attack correctly, MegaMan DS will form and try to kill MegaMan until the viruses are deleted. This MegaMan DS has no HP, but will dissipate after a long period.

It's worth noting that Dark MegaMan only appears in Mega Man Battle Network 5, and that there is a difference between him and MegaMan DS. Whereas Dark MegaMan is MegaMan overwhelmed and transformed by Dark Power, MegaMan DS is the embodiment of MegaMan's evil but was removed after then ending of Battle Network 5.

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.
