Nebula

Nebula (ネビュラ) full name DarkChip Syndicate Nebula (ネット犯罪組織ネビュラ,

''Netto hanzai soshiki nebyura. lit Net Criminal Organization Nebula) is a criminal organization from the Mega Man Battle Network'' series. The organization was led by Dr. Regal, and under his command Nebula is dedicated to infecting the entire world with darkness.

Mega Man Battle Network 4
Nebula makes its first appearance, having HeelNavis and ShadeMan.EXE and LaserMan.EXE as operatives. Noteworthy the group had a handful of human agents, but they were limited in number. They were little known before this game, but became more active. According to Eugene Chaud the group had existed even when Gospel and World 3 were at work, but following their demise Nebula became the reigning group with crimes all over the world. Their secrecy and methods (mostly involving DarkChips) led Chaud to believe they were a bigger threat than WWW.

Nebula's first attack on the net, involved ShadeMan indiscriminately assaulting NetNavis and draining their energy for food. He soon set his eyes on Roll.EXE to serve as his "dessert". Glide.EXE and GutsMan.EXE were defeated by the vampire Navi forcing Lan Hikari and MegaMan.EXE to follow him in the cyberworld of a Radio Tower. MegaMan faced ShadeMan but was unable to injure the Nebula Navi. ShadeMan began losing power and with the arrival of ProtoMan.EXE he decided to retreat but left behind a DarkChip that MegaMan took for himself, unaware of what he had.

Later an agent of Nebula trespassed the Hikari household, checked Lan's computer and sleep gassed his mother and left a note for him to come to ParkArea2 with the DarkChip. The duo did and fought a HeelNavi from the agent whom they defeated, however he threatened they would come for the DarkChip. ShadeMan later punished the two for their failure.

When Lan and Mayl Sakurai had a date in Castillo the park theme's robots began to run out of control forcing Lan and MegaMan to disable their systems. On the last Vampire-themed robot, they found ShadeMan had sabotaged all of them with the intent of reclaiming the DarkChip. He notices MegaMan is developing a DarkSoul of his own and proposes they join Nebula. MegaMan and Lan feign interest and destroy the DarkChip, angering ShadeMan who attacks them. Like before they are unable to damage him until MegaMan resorts to using his Dark Power which fatally wounds ShadeMan. The Darkloid turns into ash as he gloats that MegaMan will inevitably turn into the dark.

To gain control of the world, they planned to hijack Duo.EXE's asteroid and use it to rule the earth. First, they sabotaged Yuichiro Hikari's plan to fire a laser and destroy the asteroid by hacking into the laser. Then Dr. Regal proposed sending a NetNavi to the asteroid and got them to hold the Red Sun/Blue Moon tournament. Once Lan and MegaMan.EXE were picked, Nebula shut down communication across the Net. Lan and MegaMan had to restore communication and fight the perpetrator, a Nebula Navi. Dr. Regal gave them a transmitter. The Nebula agent committed suicide to destroy MegaMan and the transmitter that Dr. Regal gave him shut down. Regal declared MegaMan deceased and proposed that they send his NetNavi to the asteroid. NAXA had no idea that MegaMan survived and agreed. Regal sends LaserMan.EXE to the asteroid and Lan arrives and sends MegaMan. They battle and LaserMan is deleted. Then MegaMan defeats Duo and turns the asteroid away from Earth.

Mega Man Battle Network 5
Nebula reappears as the main antagonist. Their base is in a volcano. They kidnap Yuichiro Hikari at the beginning of the game, and invade the whole Net. Depending on the version, a Network official is assigned to create a team of NetNavis to reclaim the Net and defeat Nebula. The invasion of the Net is simply a distraction through while they steal Gow to build the SoulNet. They continue to build Dark Chips to gain recruits. They perform a test with several SoulNet servers before using the real thing. After Regal and Nebula Grey are defeated, Nebula ceases to exist.

MegaMan NT Warrior Axess
Nebula is still run by Dr. Regal. He hires the Darkloids to do his bidding in return for Dark Chips which he uses to make the Darkloids turn on ShadeMan. His base in in an outer space satellite instead of an volcano from which they launch Dimensional Area Generators. They commit NetCrimes to keep their base secret, steal materials for Dark Chips and enough Dimensional Area generators to engulf the Earth in an Dimensional Area. He also develops the Dark Synchro Chip which he and Ms. Yuri use. His plan comes to fruition. The Earth is engulfed by a Dimensional Area and he uses the Dark Synchro Chip to become R LaserMan.EXE. However, he is defeated by MegaMan and Lan in Cross Fusion and his Dimensional Area Generators are destroyed. Nebula ceases to exist after that.

Trivia

 * Nebula has few human agents, the ones seen being rather generic while their Navis do the bulk of the job. This may fit with Dr. Regal's overall misanthropic beliefs.
 * Nebula is the first and only evil organization to have, albeit briefly, taken full control of its respective world. This excludes Neo Arcadia which was a human settlement and wasn't evil on itself, rather misguided and mismanaged.
