Chaos Lord

The Chaos Lord, known as Lord of Chaos (ロードオブカオス) in Japan, is a secret boss that only appears in Mega Man Battle Network 5.

Game History
Chaos Lord resides in Nebula Area 6, where all of the dark energy in the world accumulates. The revived Darkloids serve the Chaos Lord and impede MegaMan.EXE's and Team Colonel/ProtoMan's attempts to reach him. After they are all defeated, Nebula Area 6 can be accessed. Nebula Area 6 contains 6 gates. Each of these gates contain a DS version of a teammate. There is also one large gate of Dark Energy that leads to the Chaos Lord. To reach the Chaos Lord, all 6 DS Navi versions of MegaMan's teammates have to be defeated. The first time MegaMan and Lan fight him, he takes the form of Nebula Gray Alpha. After he is defeated, MegaMan either receives Big Hook (Team ProtoMan) or MetrKnuckle (Team Colonel). After the first battle, he can be fought again, but this time his form may vary, but will never again be Nebula Gray Alpha. Depending on how fast MegaMan defeats the 6 DS Navis determines what form the Chaos Lord will take. He can take the form of either Nebula Gray Beta, Bass.EXE or Dark MegaMan.

Forms
The combined time for defeating the 6 DS Navis determines the form that Chaos Lord will take.

Time:

3:00:01 and up: Nebula Grey V3

2:00:01 - 3:00:00: Bass.EXE V3

2:00:01 and less: Dark Mega
