Chibis of OCs from Monochrome. This is actually the first pic with the four together.

Starting from left:

Ranu- Ex Reaper, originally used by scientists to be a apparatus for killing. She hates most humans, but trusts Ferris because he's a doctor of cybernetics.

Iris- Tactician and aide. She gives her comrades instructions via headset. She was teased long ago for having big hips, the pain still leaves a mark. She loves Rath, even though he's much older then her.

Rath- Big Boss of the group. He acts tough but inside is hurting. On a mission his former partner Robin went rogue, he had to be the one to shoot her. He tries to stay optimistic. He has feeling for Iris, but unsure how to convey them.

Ferris- Ferris is a Doctor. He feels guilty for helping create project Reaper. He always hides his eyes behind Shades covering the shame he feels.

Note: In the pic Ferris is upset cause Rath stole his Shades. He don't like showing his eyes usually.
