Appearance: 
A middle-aged man with serious eyes and a chiseled face, though his age lines suggest that time is beginning to catch up with him.  He is physically large and reasonably muscular, and keeps his dark hair cut very short.  He generally wears suits and suit coats with a matching derby hat for civilian attire.
While incognito, he sports a pinstripe black suit and suit pants, and a very thin but resilient set of flexible armor underneath his clothes.  A long black coat housing his weapons rests above his suit.  He wears glove-like gauntlets that are reinforced with steel.  A charcoal-colored mask covers all but his eyes, though the bottom half of the mask can be removed to expose his mouth and nostrils if need be.

He more closely resembles Van Alden from Boardwalk Empire than anyone else I can think of.

Name: Odest Emporio
Alias: The Rambler
Gender: Male
Age: 44
Alignment: Mercenary
Race: Human
Powers/weapons: Odest carries a long halberd with a smooth convex blade on the outside of his coat.  The inside of the coat houses a pistol and a reinforced knife, along with additional clips of ammo.  He also keeps a high-powered sniper rifle inside of his car.  

Ability: Odest is able to strengthen any of his five senses by temporarily 'turning off' one of his other senses.  For every sense he sacrifices, his remaining senses get progressively stronger, reaching superhuman levels.  Increasing his sight can allow him to enhance his vision several times over, and can allow him to see through objects and spot trails invisible to the naked eye at higher levels.  Powering up his sense of touch gives allows him to more accurately control his muscular structure and increase his strength and speed.  And so forth.  As a downside, sacrificing a particular sense at the wrong time can potentially open him up to taking an attack that he may have otherwise been able to avoid, so he must use his ability thoughtfully.
Outside of this power, Odest is particularly strong and athletic for a human being, a result of surviving through mercenary work and fighting meta-humans for many years.

History: As a boy Odest lived in poverty, and his life was further complicated by the presence of his unusual power, which was present since birth.  Most people considered him a freak, and his ability allowed him the super-hearing and super-sight that let him discover how his so-called friends really felt about him.  Eventually he eavesdropped on his parents lamenting his nature and being unsure of what to do with him.  Odest abruptly ran away from home and never looked back.  

Needing money to survive on the streets, Odest figured out how to hone and improve his ability, which allowed him to excel in jobs concerning espionage and assassination.  Taking on the alias of The Rambler, Odest soon made a good living for himself taking odd jobs that few other mercenaries were equipped to handle.  He eventually became unsatisfied with apprehending and killing normal people, and began to relish the opportunity to fight beings with 'powers' such as his.  

Odest find a great sense of fulfillment through his jobs, and when not on the clock he gluts himself on fine food, good wine and other such luxuries.  His checkered past has left him stoic and self-centered, though he is not completely beyond camaraderie. 

My favorite type of cake is peanut butter cake.
