Throughout his short existence of life, Jim had been synonymous with many titles, including some 'very' flattering ones . He was a hired gun, a mercenary, a womanizer, a demon (For those on the other side of his barrel), a gambler of both money and fate (Not having much of either), a jerk, a narcissist, and so many other names.
From his own vain (and prideful) perspective it wasn't his fault for these names. Gathering names of hired help came with the profession, being called a womanizer was because women so attracted to him. And narcissist? Of course not, he only took pride in his work (Among other things)
And the rest? Probably because of his self-gratifying behaviors. Not like everyone else lived that way too, bunch a hypocrites.
A hero (If he could be called one) created for Zombie Punk, an under-work series, sort of a mix of Hellsing and Fallout with a dash of steam-punk.
