OK, here are my creations:
Ryu, a mercenary working for the Empire.
Motto: "Mess with me and you are messing with THEM!! (His weapons ;-) )
The Necron Cyber Rocketeer:
Motto: "Fly me to the other side!!" (A parody on the song "Fly me to the moon" X-D )
Fright Face, a bounty hunter with unknown allies.
Motto: "Look into my eyes, baby!!" (Looking into his face blinds his Victims for the rest of their lifes. ;-) )
And Mortull, a clan mercenary.
Motto: "Every assignment is worth doing as long as you gettin' dirty!!"
What do you think? ;-)
