I think the most common name of the blob boss was called the Green Devil

Odd, considering that in X4 and X5 he was yellow and black...

Eh.. The creators are color blind

Name: 'Vile' (doesn't know real name, but was based off this model, so he took the name too.)
M or R: Maverick
Appearance: http://megaman.retrofaction.com/art/pics/666.jpg Just that in the RP, change his armor to black and red instead of blue and red.
Weapon: Energy Staff - Think dual bladed lightsaber, with red beams, and that is pretty much what this looks like. Energy comes out of both sides of a single handle, and the beams work mostly like a sword.
Shoulder Mounted Laser Cannon - This is a heavy weapon attached to his shoulder, with far more punch than an average arm cannon, but also it takes a while to charge and fire, and then it needs to cool down so it doesn't overheat. Best against larger and slower targets.
Shoulder Mounted Rockets - Small and fast non-homing rockets, they have a powerful punch and a good sized explosion. They shoot off a 3 missle salvo, and then needs to be reloaded.
Lazer Pistol - An average laser pistol, Vile has had it for a long time and doesn't know where it came from, just that it is more powerful then many laser pistols he's seen so far.
(So basically Vile has his two heavy weapons, a light ranged weapon, and a melee weapon.)
Background: Vile isn't quite sure what he is, and started off neutral in this war, but eventually he was captured by the Mavericks. He proved immune to the Maverick Virus, yet strangely he decided to join the Mavericks anyway, for reasons even he isn't sure of. He has looked through records anywhere he can, and has decided that he was based off of the old Reploid Hunter Vile, a very old schematic for a Reploid Hunter that was almost lost in the Maverick Database. It was a very old model and never updated, with no new models created so he doesn't know how he was created or where he came from. Despite his confusion of his origins, he proves himself to be just as fearsome now as the original version was going to be, and a threat few can stand up to, but he is usually made a partner to others so that they can keep an eye on him since he isn't infected with the Maverick Virus, just works with the Mavericks.

Since Vile was a Maverick, my guess is your guy was actually made with the Virus already in him...

Now I know the real name of the blob. It's (color) Devil. Like in X5 it's shadow Devil. I was looking a Megaman & Bass where it's the Green Devil. There cleared up.

Maverick Roster...

Vile
Uriel
Gutx Man

Wonder how everything will work out? And Vile reminds me of a Reploid Predator and all, with his shoulder cannon.

I was sort of basing him off the idea that he was made a long time ago as the last model if Vile, but went dormant or something, and was accidently reactivated recently. He would have an older version of the Maverick Virus that just isn't compatible with the new version, which is why he was inclined to join them in the first place.

Hmm... I see. Lone ranger type?

Also, if your a Maverick, at no point are you going to rebel against the Mav leader. Virus forces you to follow him, and changes how you think. Unless at some point we decide all player Mav's should become Resistance, then I'll just make up a cure or something.
