The most Megaman I know of is from NT Warrior and that seems to be as far as possible from what is in this universe. So, for once, I will intentionally keep myself blind as my character would be.
Nuurakh for..well, Nuurakh; Kronos for Vahi Design and Blaze for the MoUP Design.
Reploid (All of them will be Reploids as all the designs are robots)
Time Manipulation (If using the Vahi design), Fire Manipulation (MoUP Design) or Reploid Law Enforcement (Nuurakh Design) . Weapons would be Staves and Launcher if using the Vahi design, Swords and 'disk launcher' if using MoUP design and a built-in 'disk launcher' if the Nuurakh Design.
Maverik if Nuurakh Design, Maverik Hunter if MoUP Design or Vahi Design (Though the Vahi version will try to stay out of direct combat as he is a rather dangerous asset to use with Time Manipulation)
Appearance: (Depends on design selected)
Bio: (Optional) (Depends on selected design)
Once a Law Enforcer for extreme circumstances, this (Name of unit) was infected with the Maverick Virus and became a force of fear through its ability to cause one unoverridable command to control a Reploid it hits with its staff when on Stun Mode: Obey the will of the Unit's superior which once was to have Reploids stay in the locked down area but now, the "Robot Master" decides what is to be done but if the staff is on Lethal Mode...it will disintegrate an unarmored Reploid and vaporize a human. Known for their ferocity and ambush tactics they are also rather short tempered and impatient combined with them working in squads, making them rather unpredictable and dangerous to encounter.
This Reploid was supposedly a bodyguard unit which used its Time Manipulation ability to protect its client or charge in some way. Very rarely have they shown anything close to foresight but in theory, they should have the potential...the chances of this have been exaggerated as one in a trillion. This particular one is a last resort kind of guy that avoids getting into fights considering Time Manipulation is a rather valuable ability. He stays as far from the fighting as possible to preserve others but will give help and advice from that distance via searching for and pointing out weaknesses in an attacker to help his allies gain an advantage in a fight.
This Reploid was a prototype for units that would work in Fusion Reactors, both experimental and approved units, as a maintenance and general crew for them. They were given the ability to manipulate Fire and Plasma to be able to contain and operate reactors without risking the need to deactivate them for repairs or general operation. This one was fairly new when the Maverick Virus broke out and thus is still trying to work his civilian job while helping the Maverick Hunters in their tasks. He is rather outgoing but, as stated before, he prefers to work on things that don't involve being on the front lines of this crisis. He will fight if he is forced to but will want to escape as soon as possible without endangering his or others' safety.
Okay, here is my little brainstorm for each character design. Thoughts on it?
