Name: Brenner Silversmith
Sex: male
Age: 62
Personality (optional): Overly serious old dude who claims to have fought in a war that happened when he was only 10 and is paranoid about an imaginary enemy and mostly just wants to keep the grandkids out of trouble
Some Backstory: Tagged along to chaperone/bodyguard for his granddaughter, citing "those damned reptoids skulking around in the woods" as his reason for feeling the need to do so
Strengths:
1. bar fights (or environmentally assisted brawling if you want fancy talk)
2. marksmanship
3. scaring random strangers
4. improvised weaponry

Weaknesses:
1. always blames aliens (ignores evidence and contextual information in favor of crackpot theories)
2. drinks too much

Backpack:

several small plastic bottles (mouthwash, shampoo, conditioner, lotion) filled with homemade moonshine
6000 assorted rubber bands
heavy duty leather gloves
hand drawn map of the entire New York City underground, color coded (with notes), in a monogrammed leather notebook
wallet, contents of which are: expired concealed carry permit for the state of Florida, Canadian drivers license, and an SD card containing several thousand pages of government documents relating to UFO crashes (laminated inside a plastic rectangle the size and shape of a credit card)

I added a wallet with yet more random crap to fit him being ever so slightly nuts. Basically just random shit in it, nothing that I can think of ANY logical use for.
