Mega Man Battle Network/Walkthroughs/Mega Man Battle Network 5/Nebula Area

So you have beaten NebulaGray, but the game is not over. Every Battle Network game has a secret area, and Battle Network 5 is no exception. So, if you are ready...

Nebula Area 1
Proceed to Undernet 3, and take the left exit to Undernet 2. There, you will find a gold Mr. Prog, who will open the portal to Nebula Area 1 if you have 100 standard chips in your library. This comes at a small cost, however: your viruses that you encounter anywhere is upgraded by one level (so, instead of facing Mettaurs, for example, you will face Mettaur2s).

Enter the area, and you find yourself in Liberation Mission 7. After the mission...

Nebula Areas 2 and 3
Enter Nebula Area 2. The exit to Nebula Area 3 is locked, and you must have performed all 30 Program Advances in order to unlock it. You must pass through it for Liberation Mission 8.

After the mission...

... talk to the gold-colored Mr. Prog. If 140 standard chips are in your library, he will once again open the next door in exchange for another virus upgrade.

Nebula Areas 4 and 5
Enter Nebula Area 4, where there will be a series of locked doors. The first requires you to defeat the 5 black HeelNavis. The second requires 3 Giga Chips in your library. The third, blocking the main path, requires 40 Mega Chips in your library. The fourth requires you to have 900 base HP (ie. without Navi Customizer parts or e-Cards). The fifth door, blocking the main path, requires 180 standard chips in your library. Beyond that lies the sixth door, requiring 12 DarkChips in the library. The two doors in the top level require 30 Program Advances and 60 Mega Chips, respectively. Slightly beyond the fifth door is the exit to Nebula Area 5, which leads to Liberation Mission 9. After the mission...

Nebula Area 6
Enter Nebula Area 6, where there will be six locked doors, with three on the left and three on the right. To open them, you must defeat the omega versions of the navis that they refer to. From the entrance and going clockwise, they are:


 * A voice speaks out of nowhere. Show your power... Defeat the Navi that strikes down all. - TomahawkMan/NapalmMan
 * A voice speaks out of nowhere. Show your power... Defeat the Navi that has all the answers. - NumberMan/SearchMan.
 * A voice speaks out of nowhere. Show your power... Defeat the Navi that cures all. - ToadMan/Meddy
 * A voice speaks out of nowhere. Show your power... Defeat the Navi that commands all - Colonel/ProtoMan
 * A voice speaks out of nowhere. Show your power... Defeat the Navi that protects all - KnightMan/MagnetMan
 * A voice speaks out of nowhere. Show your power... Defeat the Navi that sees all. - ShadowMan/GyroMan

Behind each gate there will be one of the blue flames which will allow you to fight the DS versions of your teammates.

The left side will also have a BugFrag chip machine, where you put in 10 BugFrags and a random chip will be given. The center of the right side (between the gates for the team leader and the team defender) contains an invisible path that takes you to the lower level.

As for the flaming gate in the center...


 * A voice speaks out of nowhere. Show your power... Confront the darkness that lurks within you.

You'd have to beat the DS versions of your teammates (ie. all six flames). Proceed up the ramp, and there will be a cutscene

If you subsequently jack out and return to Nebula Area 6, then you will face a different opponent based on how quickly you defeat the DS navis. If the combined time is less than two minutes, you will face Chaos Lord Dark MegaMan, while Chaos Lord Nebula Grey will be your opponent if you take more than a total of three minutes. Any time in between you will face Chaos Lord Bass.

''(fight and win against Chaos Lord Bass. You will receive a BassAnly F in Team Colonel and a Bass F in Team ProtoMan.  Afterwards, Bass will appear

If you defeat Chaos Lord Bass, BassSP will be available in random battles in Nebula Area 6. Defeat him to get the last icon in the main menu.
