Personality: Nicolai is an aggressive tank of a man, happy in the thick of mech combat or in a bar room brawl. He is rowdy and will stir up trouble whenever he can, but he is most at home in the Atlas mech suit, shrugging off damage and savaging the enemy with bullets. 

History: Nicolai was a junior mech pilot working security for the Nexus corp. He joined fresh out of school and patrolled R&D hangars at the Nexus corp HQ to ensure that they where not attacked or sabotaged. The work was well paying but quite dull, he decided to have a change in career and joined the Kell Hounds Mercenary group. A tiny corporation by comparison, but they managed to farm out security and the occasional black ops assault jobs. The Kell Hounds quickly earned a name for themselves both in the combat games and in the field and Nicolai also earned his stripes with them. 

While the Hounds where still a small corp they where rapidly expanding as one of the go-to security company if a corporation couldn't afford their own security Mechs, pilots, and training. Nicolai earned an accommodation while protecting some small corporation, the warehouse was attacked by a pair of light black op mechs, the lightly armed and armored mechs where not prepared for the Atlas and where quickly dispatched. This event earned Nicolai a promotion as well, making him the Kell Hound's pilot in the arena. A veteran of combat missions, but a fresh face in the arena.

History and Development: The Atlas MK-IV was designed by the Kell Hounds Mercenary Corp specifically to run guard and assault operations, the Kell Hounds primary role. The Atlas does not have terribly impressive firepower but can survive combat that would leave most mechs in a heap of flaming wreckage. The idea began as a simple heavy mech with everything except a gun stripped down to make room for armor. As the armor evolved the Mech was scaled up and built bigger and tougher. the MK-IV was the final iteration of the mech, reaching an elegant simplicity that worked well in all situations. With the development of an extremely durable alloy it made an excellent front line battle mech that could protect the more vulerable artillery from everything but the most serious assaults. The Atlas for the arena was also equiped with several minor enhancements such as speed boosters, UAV, and higher yield missiles.

Weapons and Equipment:
MRM 5 rocket pod x2 - Medium range missiles with lock on, fires 5 High yield missiles per salvo (10 salvo capacity)
Rotary cannons x2  - Large caliber belt fed guns with high rate of fire and armor piercing ammo. 
Endo-Steel Armor - the Atlas is extremely heavily armored with a special alloy developed for this mech, it is capable of surviving severe bombardments of damage. 
Radar
Short fire boosters - thrusters that give the heavy mech some limited mobility
UAV assist - Launces a small UAV with radar and thermal imaging to aid the pilot in situational awareness
