Darkloid

Darkloids are NetNavis who, by use of Dark Chips, traded their soul for power. This dark power allows them to survive incredible amounts of damage, and even return them from deletion, but the Navi must constantly immerse themselves in the darkness, driving them insane. They work for Nebula, who supplies them with the Dark Chips they grow to crave. Darkloids are more powerful than the average Navi because of their power source, but can still be defeated.

MegaMan Battle Network 5
The Darkloids appear under the command of Nebula, who uses them to take over areas of the Net. Each Darkloid occupies a certain area of the Net, wreaking havoc and creating new Darkloids (Dark MegaMan, Dark ProtoMan and Dark Colonel) to assist them. However, Scilab and the Officials create a team to counter them: Team ProtoMan/Team Colonel (depending on the games version). They battle for control of the Net, with the Officials engaging in Liberation Missions to retake the Net. Ultimately, Team ProtoMan/Colonel triumphs-- with the aid of new recruits found along the way-- and Nebula's hold over the Net is broken. However, the Darkloids are revived, capturing Gow and infecting ProtoMan/Colonel with darkness. They proceed to set up SoulNet servers throughout the Net to test their effectiveness, driving Navis and humans insane with negative emotions. However, the servers are destroyed and ProtoMan/Colonel is restored to normal.

All of the revived Darkloids battle Team ProtoMan/Colonel in Nebula's volcano base and are defeated again. However, it is a Pyrrhic victory; in their final moments, the Darkloids summon the Dark Galaxy, trapping all of the heroes' NetNavis except MegaMan. When MegaMan tries to destroy the SoulNet server, the Darkloids appear from the Dark Galaxy to try and stop him, but Team ProtoMan/Colonel returns alongside Roll, GutsMan, and Glyde to occupy them, allowing MegaMan to stop Regal's scheme. The Darkloids are presumably defeated, as they do not reappear after the defeat of Nebula Grey.

MegaMan NT Warrior Axess
In the anime, Darkloids are many solo Netnavis that are quite powerful and seem to enjoy wrecking havoc. Dr. Hikari made a hypothesis that Darkloids are genuinely independent solo Netnavis. Since Netnavis, even solo Navis, were created by humans, Dr. Hikari assumed that Darkloids were not created by humans at all, but had created themselves. The Darkloids are led by ShadeMan, working for Nebula in exchange for Dark Chips which make them stronger. Unbeknownst to the Darkloids, however, the Dark Chips are corrupting their data, dooming them to eventual deletion. ShadeMan eventually caught on and decided to kill Regal for using the Darkloids in such a way. His attempt is foiled by LaserMan, who proceeds to take over leadership of the Darkloids. Only BubbleMan remains loyal to ShadeMan.

The Darkloids continue wreaking havoc in the name of Nebula, but they are all deleted one by one, except for BubbleMan. Dr. Regal revives them all in one of the last episodes of Axess and sends them to distract the Net Saviors, but they are all deleted in short order. ShadeMan is freed by Bass and tries to kill the Cross Fused Regal, but is deleted in the attempt.

ShadeMan is revived and BubbleMan rejoins him. They plan to take over the world and make it a home for Darkloids, but ShadeMan is deleted and BubbleMan is lost in the past. Unfortunately, before their defeat, Dark MegaMan is created by ShadeMan biting MegaMan. Dark MegaMan gathers up a new team of Darkloids to cause trouble, but all of them are deleted in the end.
