[Champion Concept] Vex, Vigilante of Piltover

Creator's Message:

 Hello everyone, and thank you for taking the time to check out my character concept. I enjoy writing very much, and I enjoy League even more, so I guess it was only a matter of time until I started writing lore of my own. I had come up with a really good story for a book, but I decided to theme it after the LoL lore. I would love, but do not expect this champion to ever be added to the game, but i thought I might as well give it a shot, right? I am very much open to ANY suggestion to this character. I will write only lore first, and then I want you guys to help me come up with his kit, weapons, additional lore, and hopefully balancing him to a reasonable character. Lastly, I must admit  that I am no artist. I would absolutely love anyone to try their best shot at making a good art concept. You can see his physical description below. Please don't be shy. Any contribution would be greatly appreciated!

Champion: Vex, Vigilante of Piltover

Weapons: Hex-tech sub-machine gun in right hand, chain wrapped around the left arm. (Uses it like a whip.)

Physical Description:

Male, about 6 feet tall, slim but not gaunt, any exposed skin is visibly scarred from burns, almost all hair is gone, seems like he was handsome before being burned, only a single eye is still functional, other eye is closed, clouded over, or bright blue in the pupil.

Clothing:

 Wearing an unbuttoned black/brown trench coat that nearly reaches the ground. Collar is flared up, going up to about nose height. Wearing a sleek, metal plate mask that covers the entire face. It is attached to a ski mask, that covers the rest of the head/neck besides the face. The mask has some sort of decoration/paintings on it. (The mask is cool, because alternate skins could have literally anything painted on the mask.) There is only a single eye hole for the single working eye. There is some emblem painted where the other eye-hole should be. Under the trench coat, he is wearing a white, button-up shirt, tucked into pants. Collar is not flared on this, (or is it?) He is wearing one of those police issued pistol carrier shoulder holsters, either black or brown. Wearing leather gloves with cut out knuckles, maybe back of hand and/or fingertips exposed. Wearing a fedora matching the coat. Wearing black tactical cargo pants tucked into black army boots. Maybe a belt. (any of this is subject to criticism and change, so give me your ideas!)

Lore:

 There are many reasons that one wears a mask. Some people wear them to hide there identity, while others wear them to strike fear into the hearts of their enemies. Some wear them to represent their cause, and some even wear them to hide their shame. I was once asked why I wear my mask, but to understand my reply, you must know who I was, before the mask.

 I was once a detective for the Piltover Police Department, and a damn good one at that. Every five days out of the week, I would to come into work, read over the files and observe the evidence of the few criminals Piltover had, and find out when and where to catch them. I spent countless weeks, months, and sometimes years hunting down criminals by following the tracks that they left behind. I loved my job. It gave me the feeling that I was playing my part in the betterment of society. It gave me purpose. However, over the years, solving case after case, that feeling of satisfaction slowly diminished. 
 

I would follow a man's tracks, get inside his head, just so when I had him, a ragtag group of trigger-happy cops would take him down. It just felt so impersonal. Paperwork had grown stale. I wanted to be part of the action! I had requested a field position, but i was always turned down, told that "You are a vital part of this establishment, but you are most effective in your current position." So I sat at that accursed desk in that accursed office, looking at those accursed files, and easily solving every accursed case put in front of me. This is how things went for some time, until the day her file came across my desk.

A giant metal hand pointed at her picture. "They call her Jinx. " Chief Vi briefed me with some conviction.
