I only found the two that are in the nebula area and I figur if I fight all his forms I can get Bass Cross on the GBA version of Megaman Battle Network 5 TC thanks to who ever answers my question.

The best soul unison for nebula grey are
The souls of Tomahawkman and shadowman

First go to End Area 2 talk to the yellow Mr. Prog begin the liberation mission begin with shadowman go up with shadowman and turn right you'll see item panel go to the panel liberate it.You'll get 2400 zenny keep doing it you'll get unlimited money if you keep at it. Note:Only shadowman can do it

The SP and DS chips all have a set attack value. These values can be increased in battle directly or indirectly. Directly would be by using Attack Plus chips. Indirectly would include chips like Roll SP and Roll DS. Roll DS base attack is 30, just like Roll and Roll SP. As a battle progresses, Roll DS attack increases by five points every time Megaman is hit with an attack, making the maximum attack of Roll DS 80. Roll and Roll SP work the same way, however those chips absorb holy panels on your side of the field, increasing the attack by five per panel. Also, the chips Django, Django SP, and Django DS have set attacks. Django's is 120, and the SP form is 150. However, just like the Roll chips, the attack of the Django chips can increase by either 50 or 60 points. This is very helpful, but the effect is random and happens at certain times.

One of the best ways that I have found when it comes to gaining money is doing the liberation missions over and over again. It may get boring after a while, but it racks up money quickly. Another way is to use the navicust program Millionaire. (I think it's called that. I know for a fact the name is something along those lines)

(Note This will work for any enemy including navis, however you have to be able to chaos union.) Use The Dark Invisible Chaos Union you will be Invunrable and you megaman will use lots of good chips to delete your enemy.

When fighting Nebula Grey,have AirShoes program installed because some of his attacks deals with the panels you stand on.

To make a folder flow you need to pick chips with the same letter code such as
Widesword S,markcannon S,and lifesync S.

By fixing your folders flow you can get the chips you need in battle quiker which will help you delete the darkloids faster.
