Nemo was born into a violent underworld where only the strongest survived. When he came of age, due to his height and strength, he was picked up by criminals and worked as an enforcer. Eventually he started working as a heavy for a group of caravan and bank robbers in the outer rim. That's where he met his only friend, the groups getaway driver, Maxon. The two worked together for a time, but when Maxon tried to leave the criminal life, their old partners turned on him. Nemo stuck by Maxon's side and they left that world behind to become free agents, always on the move, just outrunning whatever trouble they leave behind.
Nemo never had the chance to discover his own aspirations. Since he was young he always did what others told him. Nemo's owes his allegiance to his comrade Maxon. Together they travel the galaxy doing odd jobs, having run ins with the law and criminals alike. Nemo never knows where he's going or doing next, and he doesn't care so long as he's having fun. And fun usually means blowing something up.
Nemo used to work as a heavy for criminal organizations, and developed a bad reputation among common folk. His last job got extra violent, so now even those he used to work with don't care to associate with him. Because of his looks and stature, most folks do their best to avoid him.
Nemo is a Nautolan who stands at over 6 feet, and is built like a bull rancor. Nemo's skin is an aqua green, his eyes black and adapted for low light. He sports scars that tell of a violent past, and carries a huge blaster that says "try me." He wears bulky clothes covered in armored plates protecting his vital areas, along with a harness covered in spare ammo and grenades.
